1 00:00:05,080 --> 00:00:09,600 Speaker 1: What happens in the brain when we face adversity and 2 00:00:09,640 --> 00:00:13,240 Speaker 1: why do two people with the same hardship walk away 3 00:00:13,320 --> 00:00:17,760 Speaker 1: with such totally different outcomes. Is resilience something that you're 4 00:00:17,800 --> 00:00:21,040 Speaker 1: born with or is it something your brain can develop? 5 00:00:21,480 --> 00:00:24,160 Speaker 1: And if so, how, what does any of this have 6 00:00:24,239 --> 00:00:27,640 Speaker 1: to do with the diving bell and the butterfly, or 7 00:00:27,760 --> 00:00:32,199 Speaker 1: using magnetic fields to zap the brain or the less 8 00:00:32,320 --> 00:00:35,800 Speaker 1: famous partner to the brain's reward system, or. 9 00:00:35,720 --> 00:00:38,160 Speaker 2: What seemingly unrelated. 10 00:00:37,600 --> 00:00:44,800 Speaker 1: Disorders in psychiatry all have in common. Welcome to Inner 11 00:00:44,840 --> 00:00:48,120 Speaker 1: Cosmos with me David Eagleman. I'm a neuroscientist and an 12 00:00:48,159 --> 00:00:52,320 Speaker 1: author at Stanford, and in these episodes we sail deeply 13 00:00:52,400 --> 00:00:56,120 Speaker 1: into our three pound universe to understand why and how 14 00:00:56,440 --> 00:01:09,080 Speaker 1: our lives look the way they do. Today's episode is 15 00:01:09,120 --> 00:01:14,199 Speaker 1: about resilience. We all know someone who's been through hell 16 00:01:14,600 --> 00:01:18,880 Speaker 1: and somehow comes out standing. Maybe you know a person 17 00:01:19,319 --> 00:01:23,600 Speaker 1: undergoing chemotherapy who still manages to raise a family and 18 00:01:23,640 --> 00:01:27,560 Speaker 1: be a good parent, or a refugee who rebuilds their 19 00:01:27,600 --> 00:01:31,279 Speaker 1: life from nothing, or a friend who keeps going after 20 00:01:31,480 --> 00:01:35,399 Speaker 1: losing her job. There's something about resilience going on here 21 00:01:35,760 --> 00:01:38,760 Speaker 1: that's different from what a lot of other people would 22 00:01:38,800 --> 00:01:40,040 Speaker 1: do in the same situation. 23 00:01:40,760 --> 00:01:41,640 Speaker 2: We're thinking about. 24 00:01:41,400 --> 00:01:45,160 Speaker 1: This one a young man who gets an early onset 25 00:01:45,280 --> 00:01:50,680 Speaker 1: motor neuron disease and slowly ends up completely paralyzed in 26 00:01:50,720 --> 00:01:55,520 Speaker 1: a wheelchair and eventually loses his ability to speak, but 27 00:01:55,640 --> 00:01:59,560 Speaker 1: he keeps on plugging along and eventually ends up becoming 28 00:01:59,560 --> 00:02:03,400 Speaker 1: one of the premire mathematical physicists in the world. This 29 00:02:03,440 --> 00:02:06,560 Speaker 1: is the story of Stephen Hawking. How did he stay 30 00:02:06,600 --> 00:02:11,600 Speaker 1: so resilient in the face of a slowly creeping disease 31 00:02:11,880 --> 00:02:16,040 Speaker 1: that ate his body but didn't seem to slow him down? 32 00:02:16,680 --> 00:02:19,240 Speaker 2: That kind of drive, that kind of adaptation. 33 00:02:19,480 --> 00:02:23,519 Speaker 1: It raises the question what enables some people to keep 34 00:02:23,600 --> 00:02:28,760 Speaker 1: going when everything falls apart? What is human resilience made of? 35 00:02:29,760 --> 00:02:32,200 Speaker 1: In this episode, we're going to answer this question by 36 00:02:32,240 --> 00:02:34,560 Speaker 1: diving into the brain. And I'm going to do so 37 00:02:34,600 --> 00:02:37,920 Speaker 1: with my colleague and friend, Jonathan Downer, who's been on 38 00:02:37,960 --> 00:02:41,360 Speaker 1: Inner Cosmos before, and he's one of the most compassionate 39 00:02:41,440 --> 00:02:45,040 Speaker 1: and insightful thinkers that I know. He has an MD 40 00:02:45,280 --> 00:02:49,400 Speaker 1: and specializes in psychiatry, and he also has a PhD 41 00:02:49,639 --> 00:02:53,200 Speaker 1: in neuroscience, and he's become one of the world's experts 42 00:02:53,320 --> 00:02:57,480 Speaker 1: in transcranial magnetic stimulation, which is a technique that we'll 43 00:02:57,480 --> 00:02:59,880 Speaker 1: come back to in a minute now. Jonathan was on 44 00:03:00,040 --> 00:03:03,280 Speaker 1: Inner Cosmos about a year ago to talk about depression, 45 00:03:03,800 --> 00:03:07,560 Speaker 1: and that episode moved and inspired a huge number of people. 46 00:03:07,840 --> 00:03:10,320 Speaker 1: So I've wanted to sit down with Jonathan again to 47 00:03:10,520 --> 00:03:15,000 Speaker 1: zoom out the camera one notch to talk about an idea, 48 00:03:15,680 --> 00:03:20,160 Speaker 1: change and focus the idea that clinical depression is actually 49 00:03:20,680 --> 00:03:25,839 Speaker 1: one expression of a more fundamental issue, one that has 50 00:03:26,040 --> 00:03:31,120 Speaker 1: accidentally surfaced as neuroscientists around the globe have performed hundreds 51 00:03:31,120 --> 00:03:35,160 Speaker 1: and hundreds of individual studies and then looked at the 52 00:03:35,240 --> 00:03:39,080 Speaker 1: emerging shape that all of these studies were pointing to. 53 00:03:39,840 --> 00:03:42,840 Speaker 1: What we'll learn today is an issue that sets right 54 00:03:42,880 --> 00:03:45,480 Speaker 1: at the center of our lives. So let's dive in 55 00:03:45,520 --> 00:03:53,160 Speaker 1: with Jonathan Downer to understand it. So, Jonathan, we've all 56 00:03:53,200 --> 00:03:56,280 Speaker 1: known people who are in very terrible circumstances in life, 57 00:03:56,440 --> 00:03:58,760 Speaker 1: and yet they figure out a way to keep going. 58 00:03:59,200 --> 00:04:02,640 Speaker 1: So we might by this says resilience, So tell us 59 00:04:02,640 --> 00:04:06,240 Speaker 1: about resilience. Yeah, So it's a fascinating topic to get into. 60 00:04:06,800 --> 00:04:09,440 Speaker 3: I think a good example to start us off by 61 00:04:09,440 --> 00:04:12,040 Speaker 3: way of illustration. You and I in our textbook talked 62 00:04:12,040 --> 00:04:16,280 Speaker 3: about the case of Jean Boubie, who was the author 63 00:04:16,320 --> 00:04:19,719 Speaker 3: of The Diving Bell and the Butterfly. I really like 64 00:04:19,760 --> 00:04:22,760 Speaker 3: his examples. He had an absolutely horrific situation in which 65 00:04:23,000 --> 00:04:26,520 Speaker 3: this was a successful author and editor of the French 66 00:04:26,680 --> 00:04:31,599 Speaker 3: fashion magazine a magazine, and he unfortunately suffered a tiny 67 00:04:31,600 --> 00:04:33,720 Speaker 3: little stroke in his brain stem that left him with 68 00:04:33,800 --> 00:04:37,360 Speaker 3: this syndrome called locked in syndrome. And for those who 69 00:04:37,400 --> 00:04:38,960 Speaker 3: are hearing about that for the first time, it's a 70 00:04:38,960 --> 00:04:42,640 Speaker 3: horrible syndrome where the output passages from your the output 71 00:04:42,880 --> 00:04:45,040 Speaker 3: tracks from your brain down to the spinal cord, and 72 00:04:45,040 --> 00:04:48,200 Speaker 3: the muscles are just severed by the stroke. So you're 73 00:04:48,200 --> 00:04:51,520 Speaker 3: perfectly awake, you're perfectly conscious, you can feel sensations, but 74 00:04:51,560 --> 00:04:54,880 Speaker 3: you can't send any signals out to your body, and 75 00:04:54,920 --> 00:04:57,840 Speaker 3: there's no recovery. He was then bedridden and the only 76 00:04:57,880 --> 00:05:00,359 Speaker 3: part of his body he could move where he could blink, 77 00:05:00,480 --> 00:05:02,800 Speaker 3: and that was pretty much all he could do, and 78 00:05:02,880 --> 00:05:05,880 Speaker 3: with the assistance of some of the people who work 79 00:05:05,920 --> 00:05:09,280 Speaker 3: with him, he would use a blinking code to specify 80 00:05:09,400 --> 00:05:11,120 Speaker 3: letter by letter what he wanted to say. 81 00:05:11,279 --> 00:05:14,440 Speaker 1: Specifically, the assistant would read out the letters of the 82 00:05:14,440 --> 00:05:18,279 Speaker 1: alphabet in order of their frequency, and then when she 83 00:05:18,400 --> 00:05:20,880 Speaker 1: got to the right letter, he would blink his eye 84 00:05:20,920 --> 00:05:23,080 Speaker 1: and she would write down that letter and then start 85 00:05:23,160 --> 00:05:24,520 Speaker 1: the process over again. 86 00:05:24,880 --> 00:05:26,800 Speaker 3: Yeah, and so the fact that he was even able to, like, 87 00:05:26,880 --> 00:05:29,120 Speaker 3: I don't know what would happen to you or I 88 00:05:29,240 --> 00:05:30,440 Speaker 3: or most of the people I know if they were 89 00:05:30,480 --> 00:05:31,240 Speaker 3: in that situation. 90 00:05:31,400 --> 00:05:31,839 Speaker 2: Certainly. 91 00:05:32,000 --> 00:05:34,599 Speaker 3: I mean, imagine having an inch which you can't scratch 92 00:05:34,640 --> 00:05:36,440 Speaker 3: because you can't move, or a pain in your leg, 93 00:05:36,560 --> 00:05:38,400 Speaker 3: or a cramping your leg that you can't do anything 94 00:05:38,440 --> 00:05:41,920 Speaker 3: about for hours. It's very hard to maintain a positive 95 00:05:41,960 --> 00:05:45,280 Speaker 3: attitude in a situation like that. And yet he was 96 00:05:45,400 --> 00:05:49,840 Speaker 3: able to laboriously blink out an entire book describing his experience, 97 00:05:50,000 --> 00:05:53,400 Speaker 3: which the butterfly exactly. So, when I think about the 98 00:05:53,400 --> 00:05:56,200 Speaker 3: fact that, to me, the most remarkable part about this 99 00:05:56,360 --> 00:05:58,880 Speaker 3: is that is not the stroke or the fact that 100 00:05:58,880 --> 00:06:01,599 Speaker 3: there's an assistant with this amazing blinking code. To me, 101 00:06:02,320 --> 00:06:04,839 Speaker 3: the astonishing part is the fact that there's a there's 102 00:06:05,000 --> 00:06:08,480 Speaker 3: a resilient spirit in there that's capable of doing that, 103 00:06:08,480 --> 00:06:10,960 Speaker 3: that is laying there in this betting it somehow has 104 00:06:11,000 --> 00:06:13,520 Speaker 3: the patience and the resilience and the I guess the 105 00:06:13,520 --> 00:06:16,560 Speaker 3: inner fortitude to do something like that. 106 00:06:17,120 --> 00:06:18,120 Speaker 2: So what is that about? 107 00:06:18,960 --> 00:06:21,840 Speaker 3: So we I mean, there are a few different ways 108 00:06:21,839 --> 00:06:23,960 Speaker 3: of looking at resilience that's been studied to death, and 109 00:06:24,000 --> 00:06:27,160 Speaker 3: there are whole books that have been written on it. 110 00:06:27,360 --> 00:06:31,920 Speaker 3: You can talk about psychological sources of resilience. You can 111 00:06:31,960 --> 00:06:37,320 Speaker 3: talk about cultural practices and interventions and therapies that support it. 112 00:06:37,400 --> 00:06:40,840 Speaker 3: You can talk about you know, social practices that support it. 113 00:06:41,360 --> 00:06:43,200 Speaker 3: What I want to dive into a little bit is 114 00:06:43,200 --> 00:06:46,360 Speaker 3: the actual neural circuitry behind it. Because we are learning 115 00:06:46,400 --> 00:06:49,359 Speaker 3: a lot about what that neural circuitry is, and it 116 00:06:49,440 --> 00:06:52,640 Speaker 3: turns out that there are indeed specific brain circuits which 117 00:06:52,680 --> 00:06:56,159 Speaker 3: support our ability to be resilient. So, for example, a 118 00:06:56,200 --> 00:07:00,920 Speaker 3: person who suffers a terrible stroke, if these circuits are 119 00:07:00,920 --> 00:07:04,080 Speaker 3: preserved and the person can actually function a lot better 120 00:07:04,120 --> 00:07:07,160 Speaker 3: than you would expect given the circumstances they're in. And 121 00:07:07,200 --> 00:07:09,760 Speaker 3: then surprisingly, if those circuits are damaged in the stroke, 122 00:07:10,200 --> 00:07:13,640 Speaker 3: the person may have minimal physical limitations and yet is 123 00:07:13,720 --> 00:07:16,520 Speaker 3: not functioning at all. Is to sort of emotionally always 124 00:07:16,520 --> 00:07:19,360 Speaker 3: getting stuck on things, cognitively always getting stuck on things, 125 00:07:19,360 --> 00:07:21,400 Speaker 3: and just not able to get up and start moving. 126 00:07:22,040 --> 00:07:25,320 Speaker 3: So I think what would be interesting to get into 127 00:07:25,320 --> 00:07:27,360 Speaker 3: a little bit is the circuitry that we've been able 128 00:07:27,400 --> 00:07:31,240 Speaker 3: to delineate behind the general ability to be resilient to 129 00:07:31,360 --> 00:07:34,400 Speaker 3: life stresses and challenges and the general ability to function. 130 00:07:34,840 --> 00:07:37,400 Speaker 1: And just before we get into the details of the circuitry, 131 00:07:37,960 --> 00:07:41,840 Speaker 1: what is the variation in the circuitry across the population. 132 00:07:42,560 --> 00:07:43,680 Speaker 2: Yeah, so that's fascinating. 133 00:07:43,680 --> 00:07:46,000 Speaker 3: There's been a lot of studies done on that using 134 00:07:46,080 --> 00:07:49,760 Speaker 3: techniques using MRI scans. So, for example, you can have 135 00:07:49,800 --> 00:07:53,800 Speaker 3: a person going the scanner and you can actually map 136 00:07:53,880 --> 00:07:57,000 Speaker 3: the thickness of their gray matter across the hole using 137 00:07:57,000 --> 00:07:59,840 Speaker 3: a technique called boxel based morphometry. So they take all 138 00:07:59,840 --> 00:08:02,000 Speaker 3: the little voxels in the scan and they look at 139 00:08:02,040 --> 00:08:04,760 Speaker 3: how thick the grain matter is in different areas, and 140 00:08:04,800 --> 00:08:08,680 Speaker 3: they can compare people who have more resilience versus less resilience. 141 00:08:09,360 --> 00:08:11,640 Speaker 3: There was a famous study done, I guess about a 142 00:08:11,640 --> 00:08:14,920 Speaker 3: decade ago now where they did exactly the question we're 143 00:08:14,920 --> 00:08:17,160 Speaker 3: asking about. They took a whole bunch of people who 144 00:08:17,520 --> 00:08:22,120 Speaker 3: had suffered horrible adverse childhood experiences. There's actually a psychological 145 00:08:22,200 --> 00:08:26,240 Speaker 3: questionnaire called the adverse childhood experiences questionnaire. So all these people, 146 00:08:26,360 --> 00:08:29,360 Speaker 3: you know, had been through horrible traumatic experiences, and yet 147 00:08:29,360 --> 00:08:33,000 Speaker 3: a subset of them had never gone on to develop 148 00:08:33,000 --> 00:08:36,640 Speaker 3: post traumatic stress disorder or depression or any other sort 149 00:08:36,640 --> 00:08:40,800 Speaker 3: of classic you know, axis one mental disorder, and the 150 00:08:40,880 --> 00:08:43,760 Speaker 3: question was, what's going on with them? It turns out 151 00:08:43,800 --> 00:08:46,000 Speaker 3: that there were specific areas of the frontal lobes that 152 00:08:46,120 --> 00:08:49,559 Speaker 3: had thicker gray matter. In these areas we were pinpointing 153 00:08:49,640 --> 00:08:51,839 Speaker 3: specifically as an area we can get into called the 154 00:08:51,920 --> 00:08:55,480 Speaker 3: left or salalateral prefrontal cortex, but it's actually a network 155 00:08:55,520 --> 00:08:59,000 Speaker 3: of areas in the brain. Who seemed if you just had, 156 00:08:59,040 --> 00:09:01,200 Speaker 3: by luck of the draw, you happen to have more 157 00:09:01,240 --> 00:09:03,960 Speaker 3: gray matter in these areas, then you were more likely 158 00:09:04,000 --> 00:09:07,920 Speaker 3: to be resilient to even quite horrible adverse childhood experiences. 159 00:09:08,400 --> 00:09:11,679 Speaker 1: And is it luck of the draw a genetic issue 160 00:09:11,800 --> 00:09:15,000 Speaker 1: or is it environmental practices or social practices. 161 00:09:15,440 --> 00:09:17,280 Speaker 3: It's a really good point there are you know, the 162 00:09:17,320 --> 00:09:19,600 Speaker 3: literature around resilience suggests that there's a lot to this, 163 00:09:19,800 --> 00:09:22,480 Speaker 3: so you know, there is although there is some genetic 164 00:09:22,520 --> 00:09:26,640 Speaker 3: component to resilience that I think that is greatly overshadowed 165 00:09:26,679 --> 00:09:30,440 Speaker 3: by one's environment and one's psychology and one's upbringing and 166 00:09:30,480 --> 00:09:34,719 Speaker 3: the practices that one implements. Early adverse childhood experiences are 167 00:09:34,760 --> 00:09:37,920 Speaker 3: really bad for people's resilience, whereas growing up in a 168 00:09:37,960 --> 00:09:41,920 Speaker 3: supportive childhood environment and having social supports and sort of 169 00:09:41,920 --> 00:09:44,160 Speaker 3: a calm parenting environment and all the rest of it 170 00:09:44,200 --> 00:09:46,160 Speaker 3: can often provide a person with quite a lot of 171 00:09:46,160 --> 00:09:49,200 Speaker 3: resilience that they can tap into later on in life. 172 00:09:49,440 --> 00:09:52,880 Speaker 1: Yeah, although there are you know, like everything it's a 173 00:09:53,000 --> 00:09:56,360 Speaker 1: gene environment interaction. There are these studies done by Steven 174 00:09:56,400 --> 00:09:59,800 Speaker 1: Swami with monkeys where he is looking at these monkey 175 00:09:59,840 --> 00:10:05,240 Speaker 1: t and with half the adolescent monkeys he has them 176 00:10:05,440 --> 00:10:09,280 Speaker 1: with their mothers and the other half he has them 177 00:10:09,360 --> 00:10:12,200 Speaker 1: just with their peers. So they're raised with peers, and 178 00:10:12,320 --> 00:10:14,760 Speaker 1: just like in junior higher high school, monkey peers are 179 00:10:14,840 --> 00:10:19,480 Speaker 1: mean to one another. And so he looks at who 180 00:10:19,600 --> 00:10:23,679 Speaker 1: ends up doing well and who doesn't, and it turns 181 00:10:23,679 --> 00:10:26,040 Speaker 1: out it's not as obvious as you would think. It 182 00:10:26,080 --> 00:10:29,360 Speaker 1: turns out that there are genetic predispositions that cause some 183 00:10:29,400 --> 00:10:32,079 Speaker 1: of the monkeys in the bad group being raised with 184 00:10:32,120 --> 00:10:36,480 Speaker 1: their peers to still do fine and others not. So 185 00:10:36,880 --> 00:10:40,960 Speaker 1: there's definitely an interaction between how you're raised and what 186 00:10:41,040 --> 00:10:42,679 Speaker 1: you come to the table with genetically. 187 00:10:43,559 --> 00:10:44,920 Speaker 2: So let's jump. 188 00:10:44,679 --> 00:10:49,280 Speaker 1: Into what you see when you're looking at this in 189 00:10:49,320 --> 00:10:51,800 Speaker 1: the brain scanner. What are these prefrontal areas that you're 190 00:10:51,840 --> 00:10:54,160 Speaker 1: talking about. So I think that might be a good 191 00:10:54,200 --> 00:10:57,200 Speaker 1: place to start. So on the one hand, you know, 192 00:10:58,000 --> 00:11:00,960 Speaker 1: let's say we have this technique called box based morphometry 193 00:11:00,960 --> 00:11:04,000 Speaker 1: that's capable of pinpointing areas of gray matter they're thicker 194 00:11:04,080 --> 00:11:07,240 Speaker 1: versus thinner in certain groups of people. And let's say 195 00:11:07,240 --> 00:11:10,120 Speaker 1: we've used that to find people were unusually resilient to 196 00:11:10,640 --> 00:11:14,400 Speaker 1: developing access one disorders despite adverse childhood experiences. The flip 197 00:11:14,440 --> 00:11:16,360 Speaker 1: side of that would be looking at people who do 198 00:11:16,440 --> 00:11:18,880 Speaker 1: have access one disorders and saying okay. And this was 199 00:11:18,920 --> 00:11:21,800 Speaker 1: an enterprise that began, and I guess around twenty ten 200 00:11:21,920 --> 00:11:24,480 Speaker 1: or so on. They started being able to gather up 201 00:11:24,559 --> 00:11:27,679 Speaker 1: big data sets of lots of people who had succumbed 202 00:11:27,720 --> 00:11:32,959 Speaker 1: to depression or bipolar disorder OCT substance use anxiety disorders PTSD. 203 00:11:33,200 --> 00:11:35,000 Speaker 2: And this is what you mean by access one disorder, 204 00:11:35,360 --> 00:11:36,640 Speaker 2: So access one disorder exactly. 205 00:11:36,679 --> 00:11:39,719 Speaker 3: So the sort of the classic sort of psychiatric disorders 206 00:11:40,120 --> 00:11:43,400 Speaker 3: DSM one is the Diagnostic and Statistical Manual, and so 207 00:11:43,440 --> 00:11:45,680 Speaker 3: the access one of that is just one way of 208 00:11:45,800 --> 00:11:51,440 Speaker 3: describing formal clinical psychiatric disorders. So this was a team 209 00:11:51,559 --> 00:11:53,959 Speaker 3: led by a meet at Ken at Stanford University and 210 00:11:54,040 --> 00:11:57,200 Speaker 3: Madaline Goodkind was the first author, And in twenty fifteen 211 00:11:57,240 --> 00:11:59,920 Speaker 3: they gathered up over two hundred studies that had been done, 212 00:12:00,240 --> 00:12:02,040 Speaker 3: or close to two hundred studies that have been done 213 00:12:02,120 --> 00:12:04,439 Speaker 3: looking at the thickness of grain matter across all these 214 00:12:04,440 --> 00:12:07,439 Speaker 3: different disorders, and they asked a really interesting question, are 215 00:12:07,480 --> 00:12:10,080 Speaker 3: all the different disorders like OCD and PTSD are. 216 00:12:10,000 --> 00:12:10,920 Speaker 2: They completely different? 217 00:12:10,920 --> 00:12:13,199 Speaker 3: Do they all involve different brain circuits or is there 218 00:12:13,240 --> 00:12:15,920 Speaker 3: some common element like if you did a bend diagram 219 00:12:15,920 --> 00:12:19,240 Speaker 3: and overlaid them all. Is there some common element to 220 00:12:19,320 --> 00:12:21,720 Speaker 3: all the brain disorders that we have lumped into the 221 00:12:21,760 --> 00:12:25,560 Speaker 3: basket of psychiatric disorders as opposed to neurological disorders. 222 00:12:25,559 --> 00:12:27,240 Speaker 1: And so amazing by the way that we can do 223 00:12:27,280 --> 00:12:30,240 Speaker 1: this now because we have enough brain scans from enough 224 00:12:30,280 --> 00:12:32,960 Speaker 1: patients with different disorders that for the first time in 225 00:12:33,040 --> 00:12:34,199 Speaker 1: history we can ask that question. 226 00:12:34,240 --> 00:12:36,680 Speaker 2: It was fair. Yeah, absolutely, So what do they find fascinating? 227 00:12:36,720 --> 00:12:39,439 Speaker 3: So they turn out that yes, indeed, if you overlapped 228 00:12:39,440 --> 00:12:42,080 Speaker 3: all the maps of all these two hundred different studies 229 00:12:42,080 --> 00:12:45,960 Speaker 3: involving I think close to seven thousand patients versus healthy controls. 230 00:12:47,000 --> 00:12:51,000 Speaker 3: There were indeed some areas which were universally thinned out 231 00:12:51,080 --> 00:12:53,720 Speaker 3: across all these different disorders, and as you might expect, 232 00:12:53,760 --> 00:12:56,920 Speaker 3: they belong to the same network that this resilient network was, 233 00:12:56,920 --> 00:12:59,080 Speaker 3: except it was in the other direction. So people will 234 00:12:59,120 --> 00:13:01,720 Speaker 3: then use with quite thick gray matter in this network 235 00:13:01,720 --> 00:13:04,199 Speaker 3: of regions were resilient to disorder. And on the other hand, 236 00:13:04,240 --> 00:13:07,880 Speaker 3: if you looked at people who had these disorders PTSD 237 00:13:08,000 --> 00:13:10,720 Speaker 3: or anxiety, one common element they all had was that 238 00:13:10,760 --> 00:13:13,880 Speaker 3: this specific network of regions was a little bit thinner 239 00:13:15,840 --> 00:13:18,760 Speaker 3: in terms of the gray matter. There are a bunch 240 00:13:18,840 --> 00:13:22,400 Speaker 3: of different networks in the brain that perform various functions. 241 00:13:22,480 --> 00:13:24,720 Speaker 3: Some of them move your upper body or your lower body, 242 00:13:24,760 --> 00:13:27,640 Speaker 3: or do vision or hearing. This particular network having an 243 00:13:27,640 --> 00:13:29,560 Speaker 3: interesting name, it's called the salience network. 244 00:13:30,200 --> 00:13:31,959 Speaker 2: And so what was need about this popped out? 245 00:13:32,000 --> 00:13:35,080 Speaker 3: The common element across all these different disorders when people 246 00:13:35,120 --> 00:13:38,600 Speaker 3: lose their resilience is the salience network. And on the 247 00:13:38,600 --> 00:13:42,080 Speaker 3: other hand, if your salience network is intact, then you 248 00:13:42,120 --> 00:13:43,880 Speaker 3: tend to have this resilience. 249 00:13:43,520 --> 00:13:45,400 Speaker 1: So help us understand this a little bit more so, 250 00:13:45,840 --> 00:13:51,440 Speaker 1: if you have less resilience, how does that connect with 251 00:13:51,440 --> 00:13:52,559 Speaker 1: psychiatric disorders? 252 00:13:52,679 --> 00:13:55,600 Speaker 3: So that's really I think that's a really great question 253 00:13:55,679 --> 00:13:58,319 Speaker 3: and the right way of putting it. So the salience network, 254 00:13:58,440 --> 00:14:01,480 Speaker 3: it helps understand what the salience nets works function seems 255 00:14:01,480 --> 00:14:04,480 Speaker 3: to be. What was need about discovering that the salience 256 00:14:04,520 --> 00:14:07,600 Speaker 3: network was involved is that separately, people had been studying 257 00:14:07,640 --> 00:14:10,480 Speaker 3: the saliens network for fifteen years. I accidentally did my 258 00:14:10,520 --> 00:14:13,160 Speaker 3: PhD audit back in the late nineteen nineties before we really. 259 00:14:13,120 --> 00:14:13,720 Speaker 2: Knew what it was. 260 00:14:14,160 --> 00:14:17,080 Speaker 3: But its job seems to be a thing called cognitive control, 261 00:14:17,200 --> 00:14:20,440 Speaker 3: the ability to self regulate your thoughts and your behaviors 262 00:14:20,480 --> 00:14:23,920 Speaker 3: and your emotions. What's unique about it in terms of 263 00:14:23,920 --> 00:14:27,960 Speaker 3: the brain regions it involves is it has some brain 264 00:14:28,040 --> 00:14:30,320 Speaker 3: reasons that are part of the limbic system, the so 265 00:14:30,360 --> 00:14:32,560 Speaker 3: called emotional system the brain, but it also has some 266 00:14:32,600 --> 00:14:34,680 Speaker 3: areas that are part of the brain's kind of executive 267 00:14:34,720 --> 00:14:37,400 Speaker 3: function and cognitive system. So it's out of all the 268 00:14:37,480 --> 00:14:40,200 Speaker 3: various dozens of brain networks that are there, it uniquely 269 00:14:40,200 --> 00:14:42,720 Speaker 3: seems to break between the limbic system and the cognitive 270 00:14:42,760 --> 00:14:47,720 Speaker 3: system between sort of reason and emotion, and you will 271 00:14:47,760 --> 00:14:50,240 Speaker 3: see people activating it when they have to inhibit a 272 00:14:50,280 --> 00:14:53,840 Speaker 3: particular thought in order to do or a prepotent response. 273 00:14:54,160 --> 00:14:56,400 Speaker 3: So a classic example that would be the go No 274 00:14:56,520 --> 00:14:59,040 Speaker 3: Go task, which is a task where people have a 275 00:14:59,080 --> 00:15:01,320 Speaker 3: signal that tells inn apress button and then another signal 276 00:15:01,400 --> 00:15:03,240 Speaker 3: says no, wait, don't do that, and so you have 277 00:15:03,320 --> 00:15:05,080 Speaker 3: to inhibit that predisposition. 278 00:15:05,200 --> 00:15:07,520 Speaker 1: So for example, if if the banana comes on the screen, 279 00:15:07,560 --> 00:15:09,560 Speaker 1: I pound the button, and if the strawberry appears on 280 00:15:09,560 --> 00:15:11,200 Speaker 1: the screen, I have to not hit the button. 281 00:15:11,240 --> 00:15:12,840 Speaker 2: That's a great example, that'd be it. 282 00:15:13,560 --> 00:15:17,040 Speaker 3: Another example would be the classic stroop task, which in 283 00:15:17,080 --> 00:15:19,000 Speaker 3: the stroop task, this is a tricky one. If you 284 00:15:19,040 --> 00:15:20,600 Speaker 3: ever have to try it, you can They have them 285 00:15:20,600 --> 00:15:22,040 Speaker 3: online if you ever want to go and try them. 286 00:15:22,040 --> 00:15:24,440 Speaker 3: With the word blue will be written in red ink 287 00:15:24,560 --> 00:15:26,360 Speaker 3: or the word red will be written in green ink, 288 00:15:26,640 --> 00:15:28,720 Speaker 3: and you have to not say the word, which is 289 00:15:28,760 --> 00:15:30,480 Speaker 3: the thing you want to do, but you have to 290 00:15:30,520 --> 00:15:33,560 Speaker 3: actually push past that prepotent response and say the color 291 00:15:33,680 --> 00:15:36,280 Speaker 3: of the word, even though there's an interference effect there. 292 00:15:36,320 --> 00:15:39,040 Speaker 3: So the stroop task and all these things volitionally activates 293 00:15:39,040 --> 00:15:43,880 Speaker 3: your cognitive control capacity. It essentially allows you to stop 294 00:15:43,960 --> 00:15:47,080 Speaker 3: ruminating to or and to focus on what kind of 295 00:15:47,080 --> 00:15:49,600 Speaker 3: response you're going to make, so the salience network will 296 00:15:49,680 --> 00:15:52,200 Speaker 3: kick in. If a person, I'll give you an example, 297 00:15:52,280 --> 00:15:54,600 Speaker 3: if you, for example, got bored with what I was 298 00:15:54,640 --> 00:15:56,640 Speaker 3: saying right now in your mind started to wander till 299 00:15:56,720 --> 00:15:57,400 Speaker 3: yesterday or. 300 00:15:57,320 --> 00:15:59,240 Speaker 2: Tomorrow or why. 301 00:15:59,240 --> 00:16:00,760 Speaker 3: I usually say this lectures, and you know, it's a 302 00:16:00,800 --> 00:16:02,960 Speaker 3: room full of people, so you know, you could always 303 00:16:02,960 --> 00:16:04,640 Speaker 3: see the people like some people are paying attention to 304 00:16:05,080 --> 00:16:07,400 Speaker 3: It's totally natural. It's very hard to focus your attention 305 00:16:07,480 --> 00:16:09,320 Speaker 3: for a long time, so people start thinking about something 306 00:16:09,360 --> 00:16:11,800 Speaker 3: else and then maybe suddenly I say something interesting and 307 00:16:11,840 --> 00:16:14,640 Speaker 3: their attention comes back again. At that moment when you 308 00:16:14,720 --> 00:16:18,280 Speaker 3: stop mind wandering and you return to the present moment, 309 00:16:19,040 --> 00:16:23,320 Speaker 3: your salience networking is activating at that moment. For people 310 00:16:23,360 --> 00:16:25,880 Speaker 3: who have done mindfulness meditation, we've all experienced this. 311 00:16:25,960 --> 00:16:27,280 Speaker 2: You know, Okay, I'm going to be mindful. 312 00:16:27,320 --> 00:16:28,960 Speaker 3: I'm going to pay attention to my breathing, and then 313 00:16:29,000 --> 00:16:31,640 Speaker 3: after about you know, three seconds, your brain starts wandering 314 00:16:31,640 --> 00:16:33,680 Speaker 3: off to something you have to do later that day 315 00:16:33,800 --> 00:16:36,160 Speaker 3: or whatever. And then and you wander and wander and 316 00:16:36,160 --> 00:16:38,240 Speaker 3: then after about a minute you're like, oh, I actually, 317 00:16:38,320 --> 00:16:39,920 Speaker 3: I wasn't supposed to be doing that. I'm supposed to 318 00:16:39,920 --> 00:16:41,600 Speaker 3: be paying attention to my breath, and at that moment 319 00:16:41,640 --> 00:16:45,320 Speaker 3: of mindfulness you return. So at the moment of mindfulness 320 00:16:45,360 --> 00:16:48,440 Speaker 3: being again, your salience network comes on as you break 321 00:16:48,480 --> 00:16:51,040 Speaker 3: the train of thought. So we can imagine that as 322 00:16:51,040 --> 00:16:53,440 Speaker 3: we go through life, we're often not in the present moment. 323 00:16:53,480 --> 00:16:55,960 Speaker 3: We're ruminating about the past or the future or something else. 324 00:16:56,000 --> 00:16:58,360 Speaker 3: But the moment that we snap out of it and 325 00:16:58,400 --> 00:17:00,680 Speaker 3: return to the present moment the sailing this network seems 326 00:17:00,680 --> 00:17:04,000 Speaker 3: to activate every time that happens. So you can imagine 327 00:17:04,040 --> 00:17:07,200 Speaker 3: what would happen if the sailings network goes down. If 328 00:17:07,240 --> 00:17:10,040 Speaker 3: you lose that capacity to easily snap out of things, 329 00:17:10,080 --> 00:17:12,280 Speaker 3: then your ruminations will just keep going and keep going 330 00:17:12,320 --> 00:17:15,439 Speaker 3: and keep going. And the minute that you can't snap 331 00:17:15,480 --> 00:17:18,119 Speaker 3: out of things, all of a sudden, it's harder to function. 332 00:17:18,320 --> 00:17:18,560 Speaker 2: Right. 333 00:17:19,080 --> 00:17:21,240 Speaker 3: So, you know, all of us, if we're faced with 334 00:17:21,240 --> 00:17:23,600 Speaker 3: a stressful situation, let's say we start worrying about it 335 00:17:23,640 --> 00:17:26,439 Speaker 3: and thinking about something horrible that's happened, you know, if 336 00:17:26,440 --> 00:17:29,240 Speaker 3: we lost someone important to us. But as long as 337 00:17:29,240 --> 00:17:31,240 Speaker 3: we can snap out of that thought and return to 338 00:17:31,320 --> 00:17:33,680 Speaker 3: our task or our work or whatever doing. We don't 339 00:17:33,720 --> 00:17:37,000 Speaker 3: have an access one disorder. We have stress, we have distress, 340 00:17:37,080 --> 00:17:39,560 Speaker 3: but we don't have disorder. But the day you can't 341 00:17:39,600 --> 00:17:41,680 Speaker 3: snap out of it again is the day you flip 342 00:17:41,720 --> 00:17:42,880 Speaker 3: over into having a disorder. 343 00:17:44,840 --> 00:17:49,280 Speaker 1: So, with this understanding coming into focus, what kind of 344 00:17:50,520 --> 00:17:52,360 Speaker 1: therapeutic approaches are there? 345 00:17:52,480 --> 00:17:54,040 Speaker 2: Beautiful? So let's go to that. 346 00:17:54,119 --> 00:17:56,520 Speaker 3: So let me also tie that back to resilience, because 347 00:17:56,560 --> 00:17:59,160 Speaker 3: I'll say, resilience has a few different As we start 348 00:17:59,200 --> 00:18:01,359 Speaker 3: to tease apart this circuitry, we start to realize that 349 00:18:01,440 --> 00:18:04,480 Speaker 3: resilience has a few components to it. One of this 350 00:18:04,520 --> 00:18:07,040 Speaker 3: isn't the only circuit behind resilience, but one of the 351 00:18:07,080 --> 00:18:10,040 Speaker 3: circuits behind resilience is this salience network and its role 352 00:18:10,080 --> 00:18:12,800 Speaker 3: of cognitive control and the ability to snap out of 353 00:18:12,960 --> 00:18:16,280 Speaker 3: mind wandering and rumination. So that thing we call cognitive 354 00:18:16,280 --> 00:18:20,560 Speaker 3: control or cognitive flexibility is one of the ingredients of resilience, 355 00:18:21,440 --> 00:18:23,240 Speaker 3: and it is one that can be enhanced over time, 356 00:18:23,280 --> 00:18:26,280 Speaker 3: as you say, one of the classic ways to enhance it. 357 00:18:26,320 --> 00:18:29,000 Speaker 3: We know that, as I mentioned during Moments of Mindfulness, 358 00:18:29,160 --> 00:18:32,440 Speaker 3: that the salience networks engage. So people who wish to 359 00:18:32,560 --> 00:18:36,840 Speaker 3: enhance their resilience, mindfulness based stress reduction and mindfulness based 360 00:18:36,840 --> 00:18:39,719 Speaker 3: cognitive therapy are tried and true sentxuries old, I mean 361 00:18:39,800 --> 00:18:43,040 Speaker 3: thousands of years old methods that if you spend years 362 00:18:43,040 --> 00:18:45,840 Speaker 3: and years practicing, you can strengthen one your capacity to 363 00:18:46,840 --> 00:18:48,680 Speaker 3: be in the present moment or at least return to 364 00:18:48,720 --> 00:18:50,760 Speaker 3: the present moment when you need to, and to maintain 365 00:18:50,800 --> 00:18:53,480 Speaker 3: yourself there. When you're sitting there meditating for ten or 366 00:18:53,480 --> 00:18:56,360 Speaker 3: twenty minutes, every time you catch yourself and bring yourself back. 367 00:18:56,400 --> 00:18:58,159 Speaker 3: You can think about that as one rep. It's like 368 00:18:58,160 --> 00:19:00,960 Speaker 3: one sit up of this system. And so the idea 369 00:19:01,000 --> 00:19:03,399 Speaker 3: behind ten years of mindful at practices you're going to 370 00:19:03,400 --> 00:19:04,560 Speaker 3: do a whole lot of situps and at the end 371 00:19:04,640 --> 00:19:06,200 Speaker 3: that that system is going to be fairly strong. 372 00:19:06,280 --> 00:19:09,359 Speaker 1: So we have mindfulness meditation is one way to practice this. 373 00:19:09,760 --> 00:19:13,200 Speaker 1: How else are you thinking about this from the neurological point? 374 00:19:13,280 --> 00:19:15,560 Speaker 3: Yeah, I think that's great. So there are Yeah, So 375 00:19:15,640 --> 00:19:17,520 Speaker 3: that's exactly it. So that's one way of doing it. 376 00:19:18,240 --> 00:19:21,200 Speaker 3: When people go for there are. Evidence based psychotherapy is 377 00:19:21,200 --> 00:19:23,720 Speaker 3: like cognitive behavioral therapy, and that's a little bit different 378 00:19:23,720 --> 00:19:26,159 Speaker 3: from mind welellss. You're not merely returning to be present 379 00:19:26,200 --> 00:19:28,880 Speaker 3: with whatever feelings or thoughts are there. But the trick 380 00:19:29,000 --> 00:19:32,120 Speaker 3: is when you get into a difficult situation and your 381 00:19:32,400 --> 00:19:34,600 Speaker 3: emotional state goes out of control or your behavior goes 382 00:19:34,600 --> 00:19:39,080 Speaker 3: out of control. In cognitive behavioral therapy, we teach ourselves 383 00:19:39,119 --> 00:19:41,840 Speaker 3: to reframe situations or thoughts in a different way, so 384 00:19:41,840 --> 00:19:44,280 Speaker 3: we're actually exerting cognive control to look at the situation 385 00:19:44,320 --> 00:19:47,359 Speaker 3: a bit differently and figure out whether our emotions and 386 00:19:47,400 --> 00:19:50,960 Speaker 3: our thoughts are proportionate to the situation or disproportionate, and 387 00:19:50,960 --> 00:19:53,720 Speaker 3: then try and bring them back again. And that also 388 00:19:53,760 --> 00:19:56,680 Speaker 3: involves activatingly at these regions. So those are tried and 389 00:19:56,720 --> 00:19:58,680 Speaker 3: true methods that have been out there. I'm not aware 390 00:19:58,680 --> 00:20:02,159 Speaker 3: of any specific medication that in a targeted way boost 391 00:20:02,240 --> 00:20:04,480 Speaker 3: these things. So there are medications that help with the 392 00:20:04,520 --> 00:20:07,560 Speaker 3: access one disorders, but I'm not aware of a medication 393 00:20:07,640 --> 00:20:12,159 Speaker 3: that specifically does this one thing of enhancing one's cognitive control. Uh. 394 00:20:12,240 --> 00:20:15,320 Speaker 3: You know, stimulants for some people and things like ADHD 395 00:20:15,440 --> 00:20:17,399 Speaker 3: when they are is just a little underactive. There are 396 00:20:17,440 --> 00:20:20,120 Speaker 3: certain groups of people who find that they gain contentitive 397 00:20:20,119 --> 00:20:23,040 Speaker 3: control on you know, people with ADHD, for example, may 398 00:20:23,040 --> 00:20:26,119 Speaker 3: find that medications enhance their ability to exercise or exert 399 00:20:26,119 --> 00:20:26,959 Speaker 3: cognitive control. 400 00:20:43,600 --> 00:20:47,840 Speaker 1: One of your errors expertise is transcriminal magnetic stimulation, So 401 00:20:47,880 --> 00:20:49,760 Speaker 1: tell us about that. 402 00:20:49,760 --> 00:20:50,760 Speaker 2: That's exactly where I was going. 403 00:20:51,840 --> 00:20:54,440 Speaker 1: So first, for the benefit of the listenership, tell us 404 00:20:54,440 --> 00:20:58,080 Speaker 1: what TMS is, and then tell us how it applies here. 405 00:20:58,280 --> 00:21:01,320 Speaker 3: Perfect, Okay, So yes, So right now, we've got this 406 00:21:01,400 --> 00:21:04,000 Speaker 3: target circuit in the brain that we'd really love to 407 00:21:04,040 --> 00:21:06,120 Speaker 3: strengthen because if only we could strengthen it for people, 408 00:21:06,160 --> 00:21:07,960 Speaker 3: they would have more cognitive control, and they'd have more 409 00:21:07,960 --> 00:21:10,560 Speaker 3: resilience and so on. And medications don't do it for 410 00:21:10,640 --> 00:21:13,480 Speaker 3: most people, but and therapy takes a really long time, 411 00:21:13,520 --> 00:21:15,360 Speaker 3: and not everyone has the capacity to do it. 412 00:21:16,040 --> 00:21:16,920 Speaker 2: But if we could. 413 00:21:16,760 --> 00:21:19,280 Speaker 3: Somehow stimulate that area and turn it on over and 414 00:21:19,320 --> 00:21:23,000 Speaker 3: over again, like do the sit ups for people, then 415 00:21:23,080 --> 00:21:25,320 Speaker 3: you know, we could be able to strengthen it. And 416 00:21:25,400 --> 00:21:28,000 Speaker 3: the method that we're using successfully to do that right 417 00:21:28,040 --> 00:21:33,440 Speaker 3: now is called transcranial magnetic stimulation. TMS is the short form. 418 00:21:33,800 --> 00:21:37,440 Speaker 3: It's a method for stimulating the brain non invasively. So 419 00:21:37,600 --> 00:21:39,560 Speaker 3: in the old days, you want to stimulate the brain, 420 00:21:39,760 --> 00:21:42,080 Speaker 3: you have to do surgery, open up the skull and 421 00:21:42,320 --> 00:21:46,720 Speaker 3: implant use an electrode to stimulate the brain. Nowadays we 422 00:21:46,760 --> 00:21:50,080 Speaker 3: can do that non invasively using a device that stimulates 423 00:21:50,080 --> 00:21:54,680 Speaker 3: the brain through the skull using powerful focused magnetic field pulses. 424 00:21:55,359 --> 00:21:58,240 Speaker 3: So a little inductor paddles placed over the target region 425 00:21:58,240 --> 00:22:02,800 Speaker 3: of the brain and it'p little quick pulses. It's powerful 426 00:22:02,960 --> 00:22:05,119 Speaker 3: enough that if you apply the little pulses to the 427 00:22:05,119 --> 00:22:07,520 Speaker 3: area of your hand that moves your thumb, for example, 428 00:22:07,560 --> 00:22:09,560 Speaker 3: you'll actually see the person's thumb move. And I think 429 00:22:09,560 --> 00:22:11,840 Speaker 3: you and I have gone through that as a little demonstration, 430 00:22:13,560 --> 00:22:15,600 Speaker 3: and it was discovered back in the nineteen ninety is 431 00:22:15,640 --> 00:22:17,320 Speaker 3: that if you do this not once or twice, but 432 00:22:17,320 --> 00:22:19,560 Speaker 3: if you do this hundreds of times, you can strengthen 433 00:22:19,680 --> 00:22:23,760 Speaker 3: the circuits that you're stimulating via the mechanisms of neuroplasticity, 434 00:22:23,800 --> 00:22:27,000 Speaker 3: which of course you've discussed elsewhere at length. The neurons 435 00:22:27,000 --> 00:22:30,080 Speaker 3: that you fire together will gradually wire together. So when 436 00:22:30,080 --> 00:22:32,639 Speaker 3: you deliver tms to any area of the brain, not 437 00:22:32,680 --> 00:22:36,159 Speaker 3: only do you activate that area, but the other areas 438 00:22:36,160 --> 00:22:38,080 Speaker 3: it's connected to will also light up, and they all 439 00:22:38,119 --> 00:22:40,520 Speaker 3: fire together, and they all wire together. So you can 440 00:22:40,560 --> 00:22:42,440 Speaker 3: sort of do hundreds of sit ups for a person 441 00:22:42,480 --> 00:22:46,640 Speaker 3: in about three minutes of TMS using these sequences of pulses. 442 00:22:46,840 --> 00:22:50,400 Speaker 3: It's been known for a long time dorsal that TMS 443 00:22:50,440 --> 00:22:53,000 Speaker 3: two regions like the dorsalateral proof on cortex and so on. 444 00:22:54,040 --> 00:22:56,720 Speaker 3: Back in nineteen ninety five, it was first demonstrated that 445 00:22:56,760 --> 00:22:59,000 Speaker 3: this can be useful in treating depression, and then it 446 00:22:59,040 --> 00:23:00,840 Speaker 3: turned out to be useful in treating other things like 447 00:23:00,880 --> 00:23:03,680 Speaker 3: anxiety and other targets turned out to be useful in 448 00:23:03,720 --> 00:23:08,760 Speaker 3: OCD and PTSD and binge eating disorder and bolivia orvosa 449 00:23:08,800 --> 00:23:12,120 Speaker 3: and lots of other conditions. Interestingly, when we look back 450 00:23:12,200 --> 00:23:14,479 Speaker 3: at what areas we'd been stimulating back in the nineties 451 00:23:14,480 --> 00:23:16,000 Speaker 3: and later on, it turned out that a lot of 452 00:23:16,000 --> 00:23:19,480 Speaker 3: the areas we were activating with TMS corresponded very nicely 453 00:23:19,560 --> 00:23:22,879 Speaker 3: to this network, this alience network, which had been active 454 00:23:22,920 --> 00:23:26,200 Speaker 3: across many different disorders. For those of us in the field, 455 00:23:26,200 --> 00:23:28,560 Speaker 3: that solved the mystery where we come in and say, look, 456 00:23:28,680 --> 00:23:30,200 Speaker 3: I thought we were just trying to treat the page. 457 00:23:30,200 --> 00:23:32,600 Speaker 3: And when I opened my TMS clinic in twenty ten, 458 00:23:32,600 --> 00:23:34,479 Speaker 3: we kept seeing this. We'd have a person who came 459 00:23:34,480 --> 00:23:36,399 Speaker 3: from the eating disorders clinic. Oh, well, but you know 460 00:23:36,440 --> 00:23:38,119 Speaker 3: you're depressed, so let's see if we can help you. 461 00:23:38,160 --> 00:23:40,440 Speaker 3: So we treat the depression and they come back in 462 00:23:40,480 --> 00:23:42,359 Speaker 3: and they say, well, Doc, you didn't tell me my 463 00:23:42,440 --> 00:23:45,080 Speaker 3: Bolivia was going to go away. And they said, wow, 464 00:23:45,119 --> 00:23:47,880 Speaker 3: that's interesting. How do you think about that? And then 465 00:23:48,240 --> 00:23:50,520 Speaker 3: you'd have a person who came in for depression, but 466 00:23:50,560 --> 00:23:52,840 Speaker 3: their bigger picture they were a veteran with PTSD and 467 00:23:52,840 --> 00:23:55,400 Speaker 3: they come and say, you know, I'm not having flashbacks anymore. 468 00:23:55,640 --> 00:23:58,920 Speaker 3: I can walk into Walmart now without having panic attacks, 469 00:23:58,960 --> 00:24:02,680 Speaker 3: Like my anxiety is way down. You'd have other people 470 00:24:02,720 --> 00:24:05,159 Speaker 3: who'd walk in and say, you know, I took a 471 00:24:06,080 --> 00:24:08,760 Speaker 3: mindfulness course once and I just couldn't do it, but 472 00:24:08,840 --> 00:24:11,480 Speaker 3: I noticed after the TMS, now I can do mindfulness, 473 00:24:12,560 --> 00:24:14,359 Speaker 3: or say I took a therapy course once and I 474 00:24:14,400 --> 00:24:16,120 Speaker 3: tried to learn how to do CBT and I tried 475 00:24:16,119 --> 00:24:18,560 Speaker 3: the techniques and you know, I really I tried for 476 00:24:18,560 --> 00:24:20,719 Speaker 3: two years. I was like teaching it to my roommate 477 00:24:20,760 --> 00:24:22,440 Speaker 3: and she could do it, but I couldn't do it. 478 00:24:22,640 --> 00:24:24,480 Speaker 3: But now after the TMS, I can do it now, 479 00:24:24,560 --> 00:24:27,719 Speaker 3: like it actually works now. So there's a synergy between 480 00:24:27,760 --> 00:24:30,000 Speaker 3: these areas of brain and our ability to stimulate them 481 00:24:30,040 --> 00:24:32,800 Speaker 3: with TMS. And what we've noticed as we stimulate these 482 00:24:32,840 --> 00:24:35,320 Speaker 3: areas is is it turned out to be very hard 483 00:24:35,359 --> 00:24:38,440 Speaker 3: to just treat the person's depression or just treat their PTSD. 484 00:24:38,600 --> 00:24:41,080 Speaker 2: If it kicked in and worked, a lot of things 485 00:24:41,160 --> 00:24:41,640 Speaker 2: got better. 486 00:24:42,240 --> 00:24:44,800 Speaker 3: And it was really fascinating what they would come in 487 00:24:44,880 --> 00:24:47,000 Speaker 3: and you would ask them, Okay, well, okay, I see 488 00:24:47,000 --> 00:24:49,399 Speaker 3: the numbers on your scale are down, but just tell me, 489 00:24:49,440 --> 00:24:51,560 Speaker 3: in your own words, what's different now, And they say, 490 00:24:51,600 --> 00:24:52,440 Speaker 3: you know, it's really weird. 491 00:24:53,240 --> 00:24:53,439 Speaker 2: You know. 492 00:24:53,600 --> 00:24:57,760 Speaker 3: Traditionally, I'm constantly ruminating about my body image all day, 493 00:24:57,960 --> 00:25:00,280 Speaker 3: Like I can't stop thinking about my weight, I can't 494 00:25:00,280 --> 00:25:02,199 Speaker 3: think about the way I look. And then I noticed that, 495 00:25:03,000 --> 00:25:05,760 Speaker 3: you know, I had a and then someone said, someone 496 00:25:05,800 --> 00:25:08,560 Speaker 3: made a comment, my aunt made a comment about my appearance. 497 00:25:08,600 --> 00:25:11,280 Speaker 3: And normally that would have ruined my entire day, and 498 00:25:11,320 --> 00:25:13,080 Speaker 3: I would have been still ruminating about it when I 499 00:25:13,119 --> 00:25:16,120 Speaker 3: went to bed, and it was really weird. I noticed 500 00:25:16,240 --> 00:25:18,560 Speaker 3: an hour later that I just wasn't thinking about it. 501 00:25:18,760 --> 00:25:20,280 Speaker 3: I was kind of over it. I was thinking about 502 00:25:20,320 --> 00:25:22,680 Speaker 3: other things again. And so these are the kind of 503 00:25:22,680 --> 00:25:25,719 Speaker 3: things people would keep on talking about that some challenge 504 00:25:25,760 --> 00:25:28,479 Speaker 3: would come along and what they were used to over 505 00:25:29,040 --> 00:25:30,200 Speaker 3: years of having the disorders. 506 00:25:30,200 --> 00:25:32,280 Speaker 2: Not a challenger come along. Okay, that's my week gone. 507 00:25:32,359 --> 00:25:35,080 Speaker 3: I'm going to be stuck ruminating about this for the 508 00:25:35,119 --> 00:25:35,680 Speaker 3: rest of the week. 509 00:25:35,800 --> 00:25:36,919 Speaker 2: I won't be able to do anything. 510 00:25:37,400 --> 00:25:39,640 Speaker 3: And what they kept noticing was saying, yeah, I get upset, 511 00:25:39,800 --> 00:25:43,560 Speaker 3: and then twenty minutes later, I'm over it. And I said, well, 512 00:25:43,680 --> 00:25:45,480 Speaker 3: is that a weird experience? You feel like you're being 513 00:25:45,520 --> 00:25:47,439 Speaker 3: emotionally numbed or emotionally blunted. 514 00:25:47,520 --> 00:25:47,680 Speaker 2: No. 515 00:25:47,680 --> 00:25:49,520 Speaker 3: No, I still have my emotions, but I can get 516 00:25:49,520 --> 00:25:52,600 Speaker 3: over things now and I don't overreact as much as 517 00:25:52,600 --> 00:25:54,719 Speaker 3: I used to. My reaction is like sort of, you know, 518 00:25:55,000 --> 00:25:58,280 Speaker 3: more proportionate. And I find I can and say, what's 519 00:25:58,320 --> 00:26:01,840 Speaker 3: the experience like? And they use words like willpower and control? 520 00:26:02,280 --> 00:26:04,520 Speaker 3: They say, I feel more like I'm in control again. 521 00:26:04,640 --> 00:26:06,960 Speaker 3: I feel like I have that willpower thing that everyone's 522 00:26:06,960 --> 00:26:09,800 Speaker 3: been telling me. I need more of that. Their subjective 523 00:26:09,840 --> 00:26:12,919 Speaker 3: experience of having this network strengthen is an experience of 524 00:26:13,000 --> 00:26:15,080 Speaker 3: greater willpower, greater control. 525 00:26:17,200 --> 00:26:20,200 Speaker 1: And so does it matter which part of the network 526 00:26:20,320 --> 00:26:23,720 Speaker 1: was stimulated or were these many different studies stimulating various 527 00:26:23,760 --> 00:26:26,280 Speaker 1: different parts, but it all happened to be of this network. 528 00:26:26,400 --> 00:26:28,320 Speaker 3: Well, so it's been a long time piecing that together 529 00:26:28,320 --> 00:26:31,960 Speaker 3: because in the TMS literature, different people targeted. Some people 530 00:26:32,000 --> 00:26:34,160 Speaker 3: will do the left hemispheres, someone do the right hemisphere, 531 00:26:34,240 --> 00:26:37,400 Speaker 3: someone go in the middle between between the two hemispheres, 532 00:26:37,400 --> 00:26:39,399 Speaker 3: and so on. And now that we've got enough of 533 00:26:39,440 --> 00:26:41,240 Speaker 3: these studies and we put them together, it looks like 534 00:26:41,280 --> 00:26:43,800 Speaker 3: you kind of get fairly similar results no matter which 535 00:26:43,880 --> 00:26:45,919 Speaker 3: as long as it's one of the members of this 536 00:26:46,080 --> 00:26:49,479 Speaker 3: network of regions, all the other networks are lighting up 537 00:26:49,920 --> 00:26:51,920 Speaker 3: as well, And so it seems to have a similar 538 00:26:51,960 --> 00:26:55,119 Speaker 3: effect when we scan people while we do TMS. You 539 00:26:55,200 --> 00:26:58,320 Speaker 3: see that when you're stimulating one area, all the other 540 00:26:58,359 --> 00:26:59,800 Speaker 3: areas and its network will light up. 541 00:27:00,720 --> 00:27:04,240 Speaker 2: And how effective is this approach? 542 00:27:04,400 --> 00:27:07,560 Speaker 1: Is it ninety percent of patients get better in some 543 00:27:07,640 --> 00:27:08,639 Speaker 1: way as it ten percent? 544 00:27:08,920 --> 00:27:12,520 Speaker 3: So that's been that remembering the TMS is a technology. 545 00:27:12,600 --> 00:27:14,960 Speaker 3: So if you asked me the question in nineteen ninety five, 546 00:27:14,960 --> 00:27:17,120 Speaker 3: it would be asking a little bit like how far 547 00:27:17,160 --> 00:27:19,760 Speaker 3: can your electric car drive in nineteen ninety five versus 548 00:27:19,760 --> 00:27:22,119 Speaker 3: how far can your electric car drive in twenty twenty five. 549 00:27:22,080 --> 00:27:23,640 Speaker 2: There's the good. Dow says, there's progress. 550 00:27:24,800 --> 00:27:28,159 Speaker 3: The early TMS studies were only getting about ten or 551 00:27:28,160 --> 00:27:31,040 Speaker 3: fifteen percent of people their emission, but they were also 552 00:27:31,080 --> 00:27:33,560 Speaker 3: only doing about ten or fifteen sessions of treatment. And 553 00:27:33,600 --> 00:27:36,040 Speaker 3: then later studies did about thirty sessions of treatment and 554 00:27:36,080 --> 00:27:38,160 Speaker 3: got about thirty percent of people better. And then later 555 00:27:38,200 --> 00:27:40,560 Speaker 3: studies did about fifty sessions of treatment and sometimes you 556 00:27:40,560 --> 00:27:43,920 Speaker 3: get fifty percent of people better. And then other studies 557 00:27:43,960 --> 00:27:47,159 Speaker 3: were using MRI guidance to kind of fine tune the 558 00:27:47,200 --> 00:27:50,040 Speaker 3: location of the stimulation, and it turns out some people, 559 00:27:50,280 --> 00:27:52,360 Speaker 3: it turns out there because of their anatomy, you need 560 00:27:52,359 --> 00:27:55,320 Speaker 3: to have map their anatomy a little more closely to 561 00:27:55,320 --> 00:27:58,720 Speaker 3: get the coil over the right spot. But the biggest breakthrough, 562 00:27:58,760 --> 00:28:00,240 Speaker 3: I think in the last two or three years is 563 00:28:00,320 --> 00:28:06,240 Speaker 3: noticing that TMS require, as we mentioned, it requires the 564 00:28:06,240 --> 00:28:11,320 Speaker 3: brain to have neuroplasticity. Right. There are implantable brain stimulators 565 00:28:11,320 --> 00:28:13,479 Speaker 3: that people use for Parkinson's and depression and so on, 566 00:28:13,520 --> 00:28:15,440 Speaker 3: and then a surgeon will implant them like a little 567 00:28:15,440 --> 00:28:17,760 Speaker 3: pacemaker in the target circuit and then you walk around 568 00:28:17,760 --> 00:28:20,679 Speaker 3: with it all day long. TMS isn't like that you 569 00:28:20,720 --> 00:28:22,520 Speaker 3: sit in the chair, you get a session a treatment 570 00:28:22,560 --> 00:28:24,639 Speaker 3: for three minutes, and after a bunch of sessions you 571 00:28:24,720 --> 00:28:27,480 Speaker 3: then it has to keep lasting for weeks or months, 572 00:28:27,760 --> 00:28:31,200 Speaker 3: even after you've gotten the treatment done. So the only 573 00:28:31,240 --> 00:28:34,520 Speaker 3: way that that works is if you have neuroplasticity, and 574 00:28:34,560 --> 00:28:36,480 Speaker 3: some people just don't have very much. We don't know why, 575 00:28:36,520 --> 00:28:38,520 Speaker 3: but there's a lot of variation. So when we treat 576 00:28:38,520 --> 00:28:40,640 Speaker 3: a bunch of people with depression, about twenty percent of 577 00:28:40,640 --> 00:28:43,800 Speaker 3: people show really strong and really rapid response, and then 578 00:28:43,840 --> 00:28:46,000 Speaker 3: about ten percent of people show nothing at all, and 579 00:28:46,040 --> 00:28:47,800 Speaker 3: everyone else is somewhere in the middle. 580 00:28:48,200 --> 00:28:49,640 Speaker 2: It's almost like you're bailing. 581 00:28:49,360 --> 00:28:51,040 Speaker 3: A bit of a leaky boat, so you're kind of 582 00:28:51,240 --> 00:28:53,240 Speaker 3: bailing it out, but they're getting worse, and then they 583 00:28:53,280 --> 00:28:55,440 Speaker 3: tend to keep coming back. These are the ones who 584 00:28:55,480 --> 00:28:57,840 Speaker 3: seem to need more plasticity. And one of the ways 585 00:28:57,920 --> 00:29:00,000 Speaker 3: that has just come out in the last two orths 586 00:29:00,240 --> 00:29:03,080 Speaker 3: years to make TMS a lot better is it turns 587 00:29:03,080 --> 00:29:05,880 Speaker 3: out that there are some simple, off the shelf old 588 00:29:05,920 --> 00:29:09,720 Speaker 3: medications that enhance the brain's plasticity, and if you take 589 00:29:09,760 --> 00:29:12,160 Speaker 3: those medications a little like an hour or so before 590 00:29:12,200 --> 00:29:14,720 Speaker 3: you get your TMS sessions, it works a lot better, 591 00:29:14,880 --> 00:29:16,440 Speaker 3: and it lasts a lot longer. 592 00:29:17,160 --> 00:29:19,280 Speaker 1: Give us a sense of what some of these meds are, 593 00:29:19,400 --> 00:29:21,240 Speaker 1: just in case the name strikes that any was familiar. 594 00:29:21,400 --> 00:29:22,800 Speaker 2: Happy to do it, so there is. 595 00:29:23,200 --> 00:29:26,600 Speaker 3: So my colleague Alex McGear at the University of Calgary 596 00:29:26,640 --> 00:29:28,920 Speaker 3: back in twenty twenty two publish a paper in Gemo 597 00:29:28,920 --> 00:29:32,720 Speaker 3: Psychiatry using an old it's actually an old anti tuberculosis 598 00:29:32,800 --> 00:29:37,400 Speaker 3: medication called de cyclosarine. Decyclo Sarine works on the brain's 599 00:29:37,400 --> 00:29:39,760 Speaker 3: glutamate system. If we want to get really nerdy, it 600 00:29:39,880 --> 00:29:43,400 Speaker 3: acts on the NMDA receptor. The NMDA receptor is the 601 00:29:43,440 --> 00:29:46,200 Speaker 3: receptor that detects whether two neurons are being fired at 602 00:29:46,200 --> 00:29:49,080 Speaker 3: the same time and then responds to that by strengthening 603 00:29:49,080 --> 00:29:51,800 Speaker 3: the connection between them. So you need your NMDA receptors 604 00:29:51,800 --> 00:29:54,080 Speaker 3: to do that whole plasticity thing where the neurons that 605 00:29:54,120 --> 00:29:57,240 Speaker 3: fire together wire together. So what happens if you add 606 00:29:57,280 --> 00:29:59,960 Speaker 3: a medication that tickles the NMDA receptor and kind of 607 00:30:00,160 --> 00:30:02,520 Speaker 3: helps it stay open a little bit longer and then 608 00:30:02,600 --> 00:30:05,200 Speaker 3: do the tms. Decycoserian has been around since the fifties 609 00:30:05,240 --> 00:30:08,000 Speaker 3: and psychiatrists have been using it and medical researchers have 610 00:30:08,040 --> 00:30:10,160 Speaker 3: been using it not for tuberculosis, but to try and 611 00:30:10,320 --> 00:30:13,560 Speaker 3: enhance plasticity while they give therapy and give other kinds 612 00:30:13,560 --> 00:30:18,120 Speaker 3: of treatments exposure therapy and phobias and OCD and so on, 613 00:30:18,520 --> 00:30:22,040 Speaker 3: And I think one of my colleagues described the results 614 00:30:22,040 --> 00:30:25,080 Speaker 3: as myth after many many years, the result was sort 615 00:30:25,080 --> 00:30:27,880 Speaker 3: of some But interestingly, it might just be that those 616 00:30:27,960 --> 00:30:30,600 Speaker 3: kind of therapies don't provide the direct kind of potent 617 00:30:30,720 --> 00:30:33,920 Speaker 3: immediate stimulation of the neural connections the way that TMS does. 618 00:30:33,960 --> 00:30:37,280 Speaker 3: Because the first time this was tried for TMS, the 619 00:30:37,320 --> 00:30:41,680 Speaker 3: effect was not small. It doubled the remission rate, and 620 00:30:41,680 --> 00:30:44,040 Speaker 3: that was just giving it for the first ten out 621 00:30:44,040 --> 00:30:46,920 Speaker 3: of twenty sessions of TMS. You know, instead of the 622 00:30:46,960 --> 00:30:49,840 Speaker 3: twenty percent remission rate you might expect with twenty sessions, 623 00:30:49,840 --> 00:30:53,040 Speaker 3: it went up to forty percent. And then actually just 624 00:30:53,120 --> 00:30:55,560 Speaker 3: two months ago Alex mcgerr's team went back and they 625 00:30:55,720 --> 00:30:58,880 Speaker 3: tried it again for all twenty sessions and the remission 626 00:30:58,960 --> 00:31:03,960 Speaker 3: rate went from twenty percent to seventy percent, eighty five 627 00:31:03,960 --> 00:31:06,360 Speaker 3: percent of people showing at least. So it turns out 628 00:31:06,360 --> 00:31:09,200 Speaker 3: there are a lot of people who just need more 629 00:31:09,240 --> 00:31:11,680 Speaker 3: plasticity to do well on TMS, and TMS actually can 630 00:31:11,760 --> 00:31:14,920 Speaker 3: be extremely powerful if you just enhance the plasticity first. 631 00:31:15,280 --> 00:31:18,120 Speaker 3: So that was and then of course this is just 632 00:31:18,160 --> 00:31:21,000 Speaker 3: about depression. So he also went to a different brain 633 00:31:21,040 --> 00:31:24,520 Speaker 3: area that was involved in OCD. Because there is a 634 00:31:24,520 --> 00:31:28,360 Speaker 3: TMS protocol for OCD, OCD is a tough nut to 635 00:31:28,400 --> 00:31:32,880 Speaker 3: crack among TMS researchers. We think of it obsessed with 636 00:31:32,920 --> 00:31:35,280 Speaker 3: compulsive disorders reckoned to be one of the toughest things, 637 00:31:35,760 --> 00:31:40,000 Speaker 3: just for when they do clinical studies on OCD, they 638 00:31:40,000 --> 00:31:43,239 Speaker 3: will often declare thirty five percent improvement in symptoms as 639 00:31:43,640 --> 00:31:46,680 Speaker 3: a strong response, and they if you like, we don't 640 00:31:46,720 --> 00:31:48,600 Speaker 3: expect to cure you of your OCD. If we can 641 00:31:48,640 --> 00:31:50,480 Speaker 3: even get your thirty five percent better, we'll call that 642 00:31:50,520 --> 00:31:54,760 Speaker 3: a win. That's often how structure studies are done. Alex 643 00:31:54,880 --> 00:31:57,600 Speaker 3: mcgear's team when they did this in OCD, they found 644 00:31:57,600 --> 00:32:01,560 Speaker 3: that twenty sessions. Uh, there's a school or there's a 645 00:32:01,560 --> 00:32:04,200 Speaker 3: scale from zero to forty called the Yale Brown Obsessive 646 00:32:04,240 --> 00:32:07,200 Speaker 3: Compulsive Score. It's the standard clinical scale you used to 647 00:32:07,240 --> 00:32:11,360 Speaker 3: measure how bad somebody's OCD is. And you know you'll 648 00:32:11,360 --> 00:32:13,240 Speaker 3: have a person who might have a score of twenty 649 00:32:13,280 --> 00:32:15,480 Speaker 3: six which would be severe, or thirty which would be 650 00:32:15,600 --> 00:32:20,800 Speaker 3: very severe, and twenty sessions of TMS would reduce their 651 00:32:20,840 --> 00:32:24,520 Speaker 3: score by about two or three points, but with decyclicerine 652 00:32:24,640 --> 00:32:27,479 Speaker 3: it was closer to ten points of reduction in twenty sessions. 653 00:32:27,600 --> 00:32:29,640 Speaker 2: Great, so it's a big difference. 654 00:32:29,720 --> 00:32:31,760 Speaker 3: And you know, the question is, well, okay, TMS is 655 00:32:31,800 --> 00:32:34,000 Speaker 3: used for lots of other things, like TMS is being 656 00:32:34,040 --> 00:32:36,480 Speaker 3: used for other brain circuits and Parkinson's and Alzheimer's, so 657 00:32:36,880 --> 00:32:39,320 Speaker 3: could this be used to treat lots of things. There's 658 00:32:39,360 --> 00:32:43,360 Speaker 3: a second wave of enhancing plasticity, which is dopamine. So 659 00:32:43,520 --> 00:32:45,240 Speaker 3: dopamine has a lot of roles in the brain, but 660 00:32:45,280 --> 00:32:48,360 Speaker 3: it does look like TMS relies upon dopamine for at 661 00:32:48,400 --> 00:32:51,600 Speaker 3: least some of the plasticity. And there have been studies 662 00:32:51,640 --> 00:32:54,280 Speaker 3: done in both in laboratory and in the real world 663 00:32:54,640 --> 00:32:57,520 Speaker 3: in which if you give people medications that boost their 664 00:32:57,560 --> 00:33:01,040 Speaker 3: dopamine levels, like el dopa for example, Parkinson's drug that 665 00:33:01,360 --> 00:33:03,800 Speaker 3: adds dopamine to the brain, and then you do the 666 00:33:03,840 --> 00:33:07,400 Speaker 3: TMS the excited where ATMs protocols get stronger, the effect 667 00:33:07,400 --> 00:33:09,880 Speaker 3: of the TMS gets stronger, so you're boosting plasticity. 668 00:33:10,040 --> 00:33:10,560 Speaker 2: So it looks like. 669 00:33:10,560 --> 00:33:13,440 Speaker 3: There's at least two or three different receptor and neurotransmitter 670 00:33:13,480 --> 00:33:14,040 Speaker 3: systems that. 671 00:33:14,000 --> 00:33:16,280 Speaker 2: Can be used to do this. How about a seedyl colin. 672 00:33:16,720 --> 00:33:17,680 Speaker 2: That's an interesting one. 673 00:33:17,760 --> 00:33:20,760 Speaker 3: So that hasn't been try yet, but you know there 674 00:33:20,840 --> 00:33:24,200 Speaker 3: are easily four or five or six different methods for 675 00:33:24,280 --> 00:33:26,480 Speaker 3: doing this. I don't know if you've had Lee Williams 676 00:33:26,560 --> 00:33:28,520 Speaker 3: come in and talks of Lee Williams here at Stanford 677 00:33:28,560 --> 00:33:33,239 Speaker 3: has been looking at it at guanphisine, not necessarily on 678 00:33:33,240 --> 00:33:35,200 Speaker 3: a cell colin, but looking at guanfessine to see what 679 00:33:35,400 --> 00:33:41,680 Speaker 3: that's a third neurotransmitter system involving neuropinephrin, and has been 680 00:33:41,720 --> 00:33:45,160 Speaker 3: showing that people with problem there are specific people with 681 00:33:45,240 --> 00:33:49,640 Speaker 3: depression who stand out for having particularly prominent difficulties with 682 00:33:49,720 --> 00:33:53,960 Speaker 3: cognitive control. And here's a medication called guafisene that isn't 683 00:33:53,960 --> 00:33:57,600 Speaker 3: normally used as an antidepressant, but in these patients, they 684 00:33:57,680 --> 00:33:59,680 Speaker 3: who happen to have what they call the cognitive control 685 00:33:59,760 --> 00:34:04,000 Speaker 3: that fense. This medication does work as an antidepressant for 686 00:34:04,000 --> 00:34:07,840 Speaker 3: these folks, probably by enhancing their cognitive control so they 687 00:34:07,840 --> 00:34:09,600 Speaker 3: don't get stuck in rumination all the time. 688 00:34:09,920 --> 00:34:12,800 Speaker 1: Right, Yeah, you know, this is such an exciting moment 689 00:34:12,800 --> 00:34:17,040 Speaker 1: in time. We're in neuroscience where everybody has been doing 690 00:34:17,120 --> 00:34:21,560 Speaker 1: these studies and we well know that to get a 691 00:34:21,640 --> 00:34:24,719 Speaker 1: patient and do a study and so on a ton 692 00:34:24,760 --> 00:34:27,960 Speaker 1: of work to do one patient, two patients, and suddenly 693 00:34:27,960 --> 00:34:31,080 Speaker 1: we can do these meta analyzes and put together the 694 00:34:31,120 --> 00:34:35,080 Speaker 1: big picture and start seeing the jigsaw puzzle more broadly. 695 00:34:35,200 --> 00:34:38,680 Speaker 1: So what our next steps. We're almost halfway through twenty 696 00:34:38,680 --> 00:34:40,160 Speaker 1: twenty five. Now where is this all going? 697 00:34:40,200 --> 00:34:43,920 Speaker 3: Absolutely so, first of all, one of the there are 698 00:34:43,960 --> 00:34:46,960 Speaker 3: two directions that the field is going in right now. 699 00:34:47,040 --> 00:34:49,400 Speaker 3: One of them, which I think is a broader trend 700 00:34:49,440 --> 00:34:52,480 Speaker 3: in psychiatry in general, is the field of personalized medicine. 701 00:34:52,520 --> 00:34:54,360 Speaker 3: So let's look at your symptoms and let's see if 702 00:34:54,400 --> 00:34:57,879 Speaker 3: we can achieve a higher chance of success by looking 703 00:34:57,960 --> 00:35:01,000 Speaker 3: at your specific symptoms and personalizing maybe the frequency of 704 00:35:01,000 --> 00:35:03,000 Speaker 3: treatment or the type of medication we use, or the 705 00:35:03,040 --> 00:35:06,479 Speaker 3: location of the coil based on your specific parameters. Which 706 00:35:06,520 --> 00:35:08,600 Speaker 3: is great if it works, but the downside of courses, 707 00:35:08,640 --> 00:35:10,520 Speaker 3: it also has a lot more complexity. So you know, 708 00:35:10,600 --> 00:35:13,080 Speaker 3: psychiatric treatments are already costly and hard to get, and 709 00:35:13,120 --> 00:35:15,080 Speaker 3: so this makes them more costly and more hard to 710 00:35:15,120 --> 00:35:18,279 Speaker 3: get the other potential approach that we could try not 711 00:35:18,320 --> 00:35:19,640 Speaker 3: to say that then there's certainly going to be a 712 00:35:19,719 --> 00:35:22,160 Speaker 3: role for that. Personalized medicine is certainly looking very exciting. 713 00:35:22,560 --> 00:35:25,799 Speaker 3: But there are some things there's a different approach where 714 00:35:25,840 --> 00:35:27,960 Speaker 3: we try not to personalize and when we simply try 715 00:35:27,960 --> 00:35:29,880 Speaker 3: to come up with the sort of greatest good for 716 00:35:29,920 --> 00:35:32,400 Speaker 3: the greatest number approach. And so I want to unpack 717 00:35:32,440 --> 00:35:36,160 Speaker 3: that a little bits to point at the idea that 718 00:35:36,200 --> 00:35:38,239 Speaker 3: there might be some brain story. I mentioned earlier, there 719 00:35:38,280 --> 00:35:41,040 Speaker 3: are some brain circuits that are universally involved across a 720 00:35:41,120 --> 00:35:44,160 Speaker 3: variety of different disorders. And so one of the questions 721 00:35:44,160 --> 00:35:45,920 Speaker 3: I asked one of my colleagues at Harvard who have 722 00:35:45,960 --> 00:35:48,399 Speaker 3: been doing one of these brain mapping type studies and seeing, 723 00:35:48,440 --> 00:35:51,320 Speaker 3: instead of mapping the circuits that are associated with depression 724 00:35:51,640 --> 00:35:55,600 Speaker 3: or PTSD or addictions or whatever, we notice that some 725 00:35:55,640 --> 00:35:58,760 Speaker 3: people just have resilience, so they actually function much better 726 00:35:58,800 --> 00:36:01,560 Speaker 3: than expected. For those of us whore working clinics and 727 00:36:01,560 --> 00:36:03,320 Speaker 3: see thousands of patients, you'll see these people who have 728 00:36:03,440 --> 00:36:06,600 Speaker 3: like terrible depression and yet somehow like they're still functioning 729 00:36:06,640 --> 00:36:09,440 Speaker 3: really well. Or people who have terrible Parkinsons and can 730 00:36:09,440 --> 00:36:12,560 Speaker 3: barely move, and somehow they're still kind of functioning or 731 00:36:12,600 --> 00:36:14,359 Speaker 3: you know, have had a stroke that's crippling to them, 732 00:36:14,360 --> 00:36:17,359 Speaker 3: and as we mentioned earlier, somehow still functioning and then 733 00:36:17,600 --> 00:36:20,719 Speaker 3: functioning mentally and in the activities of daily life, like yes, 734 00:36:20,760 --> 00:36:24,239 Speaker 3: they're super you know, there's somehow still. I actually saw 735 00:36:24,280 --> 00:36:27,600 Speaker 3: a gentleman, what was it, I don't know whose name. 736 00:36:27,600 --> 00:36:29,799 Speaker 3: We were having brunction pol Walta just up the road 737 00:36:30,680 --> 00:36:33,279 Speaker 3: and there was a little man, it looked in his 738 00:36:33,360 --> 00:36:36,040 Speaker 3: nineties in a wheelchair by himself, and he was out 739 00:36:36,040 --> 00:36:38,160 Speaker 3: for a while. He was using one leg and his 740 00:36:38,200 --> 00:36:40,880 Speaker 3: heel to drag his wheelchair along one foot at a time, 741 00:36:41,200 --> 00:36:42,920 Speaker 3: and he smiled and waved to us, and he kind 742 00:36:42,920 --> 00:36:45,719 Speaker 3: of crept along sidewalk for his morning stroll. And he 743 00:36:45,920 --> 00:36:48,040 Speaker 3: was and I don't know who got him into the 744 00:36:48,120 --> 00:36:49,759 Speaker 3: chair or how he's getting along, but there he was, 745 00:36:49,760 --> 00:36:52,000 Speaker 3: just using one foot to drag himself around the block 746 00:36:52,040 --> 00:36:54,320 Speaker 3: for a little morning scroll. And so we can evaluate 747 00:36:54,360 --> 00:36:57,440 Speaker 3: how severe your symptoms are, but we can independently evaluate 748 00:36:57,520 --> 00:37:00,560 Speaker 3: how well you're functioning in daily life. So that gentlemen 749 00:37:00,600 --> 00:37:02,200 Speaker 3: I mentioned would be an example of someone who if 750 00:37:02,239 --> 00:37:04,520 Speaker 3: you measured their physical symptoms, they would be totally crippled. 751 00:37:04,520 --> 00:37:06,120 Speaker 2: But if you actually they're still. 752 00:37:06,120 --> 00:37:08,640 Speaker 3: Getting up every morning and walking around and having breakfast 753 00:37:08,640 --> 00:37:10,919 Speaker 3: and doing all their stuff, So on that level, they're 754 00:37:10,920 --> 00:37:13,400 Speaker 3: better than expected. So the question becomes, let's run an 755 00:37:13,320 --> 00:37:16,360 Speaker 3: analysis of strokes or lesions or other things and figure 756 00:37:16,360 --> 00:37:19,600 Speaker 3: out are there areas that correlate with your better than 757 00:37:19,760 --> 00:37:22,640 Speaker 3: expected or worse than expected number if we think of that, 758 00:37:22,719 --> 00:37:25,360 Speaker 3: But and they do, they pop out and one of 759 00:37:25,400 --> 00:37:27,000 Speaker 3: the two There are two circuits that popped out of 760 00:37:27,000 --> 00:37:30,799 Speaker 3: that analysis, which was led by Beatrice Milano and with 761 00:37:30,840 --> 00:37:33,200 Speaker 3: my colleague Shan Sidiki and his group over at Harvard. 762 00:37:33,440 --> 00:37:35,200 Speaker 3: They went through a whole bunch of stroke patients and 763 00:37:35,239 --> 00:37:39,680 Speaker 3: they looked at their ability to function in general. And 764 00:37:39,719 --> 00:37:43,120 Speaker 3: the circuits that popped out. Number one involved this one 765 00:37:43,120 --> 00:37:45,840 Speaker 3: of these salients network circuits that I talked about. But 766 00:37:45,880 --> 00:37:48,560 Speaker 3: there was a second circuit that was down just above 767 00:37:48,560 --> 00:37:50,719 Speaker 3: the eye in another circuit we haven't gotten to yet, 768 00:37:50,719 --> 00:37:54,640 Speaker 3: called the orbit of frontal cortex, and it was also involved, 769 00:37:54,640 --> 00:37:56,920 Speaker 3: but in the opposite polarity. In other words, it was 770 00:37:56,920 --> 00:37:59,120 Speaker 3: actually good to have lesions in this area. And if 771 00:37:59,120 --> 00:38:01,080 Speaker 3: this area was preserved you were more likely to be 772 00:38:01,120 --> 00:38:03,880 Speaker 3: functionally impaired. How do we understand that? So that's an 773 00:38:03,880 --> 00:38:07,280 Speaker 3: interesting one because this circuit is also pretty well studied 774 00:38:08,120 --> 00:38:11,080 Speaker 3: and it is the counterpart to the brain's so called 775 00:38:11,120 --> 00:38:13,640 Speaker 3: reward circuit. So the brain most of us know, has 776 00:38:13,640 --> 00:38:15,359 Speaker 3: this sort of a reward circuit whose job it is 777 00:38:15,400 --> 00:38:19,200 Speaker 3: to identify goals that are worth pursuing and to motivate 778 00:38:19,280 --> 00:38:21,840 Speaker 3: us to go and pursue those goals. The problem is 779 00:38:21,840 --> 00:38:24,160 Speaker 3: that that would only allow us to pursue positive goals. 780 00:38:24,200 --> 00:38:28,320 Speaker 3: We also need a partner circuit to identify potential pitfalls 781 00:38:28,360 --> 00:38:32,440 Speaker 3: or problems, challenges, threats, and to establish goals to avoid 782 00:38:32,440 --> 00:38:35,160 Speaker 3: those things and motivate ourselves to avoid those. If you 783 00:38:35,200 --> 00:38:37,719 Speaker 3: don't have both circuits, you're in trouble. The brain needs 784 00:38:37,760 --> 00:38:40,240 Speaker 3: to be motivated to seek out stuff, but also needs 785 00:38:40,239 --> 00:38:43,319 Speaker 3: to be motivated to avoid the bad stuff. And the 786 00:38:43,360 --> 00:38:46,960 Speaker 3: circuit that was overactive in these stroke patients, or so 787 00:38:47,000 --> 00:38:49,440 Speaker 3: to speak, or was the one that was the so 788 00:38:49,480 --> 00:38:53,000 Speaker 3: called non reward circuit, whose job it was to be 789 00:38:53,040 --> 00:38:57,480 Speaker 3: motivated to essentially to generate negative motivations. 790 00:38:58,640 --> 00:39:01,120 Speaker 1: It looks like, so you said that was overactive in 791 00:39:01,120 --> 00:39:03,759 Speaker 1: the stroke patients is that there's a specific thing we 792 00:39:03,800 --> 00:39:06,080 Speaker 1: think is happening in that circuit, it can enter into 793 00:39:06,080 --> 00:39:07,560 Speaker 1: a feedback loop, right. 794 00:39:07,640 --> 00:39:10,560 Speaker 3: And this is a theory by a professor in the 795 00:39:10,680 --> 00:39:14,239 Speaker 3: UK called Professor Edmund Rules. He'd been studying the orbit 796 00:39:14,280 --> 00:39:17,600 Speaker 3: of frontal cortex region in monkeys and humans for decades 797 00:39:18,560 --> 00:39:21,640 Speaker 3: and he after many years, realized that this circuit tended 798 00:39:21,640 --> 00:39:24,600 Speaker 3: to get stuck in a feedback loop in depression, and 799 00:39:25,360 --> 00:39:29,040 Speaker 3: he proposed what I think is a very lovely theory 800 00:39:29,040 --> 00:39:31,920 Speaker 3: called the non reward attractor theory of depression. So, in 801 00:39:31,960 --> 00:39:34,759 Speaker 3: the non reward attractor theory of depression, you have a 802 00:39:34,800 --> 00:39:38,560 Speaker 3: circuit whose job it is, to what it's functioning properly, 803 00:39:38,680 --> 00:39:41,239 Speaker 3: is to identify threats, so you can then start to 804 00:39:41,280 --> 00:39:44,440 Speaker 3: think about solutions and go and solve them. But if 805 00:39:44,480 --> 00:39:46,279 Speaker 3: it gets stuck in a feedback loop, then you can't 806 00:39:46,280 --> 00:39:48,640 Speaker 3: stop thinking about it even when you're not solving it. 807 00:39:49,080 --> 00:39:52,200 Speaker 3: I think all of us have experienced the sensation at 808 00:39:52,200 --> 00:39:54,480 Speaker 3: times of the difference between you know, working on a 809 00:39:54,520 --> 00:39:56,960 Speaker 3: problem versus just worrying about a problem where you're not 810 00:39:57,000 --> 00:39:58,520 Speaker 3: really solving it, but you're awake at two in the 811 00:39:58,520 --> 00:40:00,319 Speaker 3: morning years thinking about the same thing over and over 812 00:40:00,360 --> 00:40:02,040 Speaker 3: and over again, and you're not really getting anywhere, but 813 00:40:02,120 --> 00:40:03,839 Speaker 3: you just keep going and keep going, and you can't 814 00:40:03,840 --> 00:40:05,840 Speaker 3: get back to sleep, and you really just need to 815 00:40:05,880 --> 00:40:07,719 Speaker 3: stop thinking about it because you're not going to solve 816 00:40:07,719 --> 00:40:09,160 Speaker 3: it right now, and snap out of it and go 817 00:40:09,200 --> 00:40:12,080 Speaker 3: back to sleep now if you can't. And if that 818 00:40:12,120 --> 00:40:14,440 Speaker 3: goes on all day long, you're not functioning because you're 819 00:40:14,440 --> 00:40:17,080 Speaker 3: sitting there ruminating and going round and around on problems. 820 00:40:17,400 --> 00:40:19,200 Speaker 3: Maybe it's a one out of ten problem that your 821 00:40:19,239 --> 00:40:21,080 Speaker 3: brain is treating as a ten out of ten problem. 822 00:40:21,800 --> 00:40:23,440 Speaker 3: Maybe it's a three out of ten problem that your 823 00:40:23,440 --> 00:40:26,239 Speaker 3: brain should be spending five minutes on and spending eight 824 00:40:26,280 --> 00:40:28,640 Speaker 3: hours on. But the point is that while it's doing that, 825 00:40:28,880 --> 00:40:31,800 Speaker 3: you're not getting up, you're not having breakfast, you're not functioning, 826 00:40:31,840 --> 00:40:33,680 Speaker 3: you're not going to work, you're not really you're not 827 00:40:33,719 --> 00:40:52,400 Speaker 3: fully present, you're not doing things. 828 00:40:53,440 --> 00:40:54,680 Speaker 2: I'll give you an example of this. 829 00:40:54,719 --> 00:40:57,960 Speaker 3: There was a woman described in the literature who is she, 830 00:40:58,880 --> 00:41:02,600 Speaker 3: among other things, had she had sought treatment for many 831 00:41:02,640 --> 00:41:04,919 Speaker 3: years for alcohol dependence. So she was somebody who drank 832 00:41:05,160 --> 00:41:08,520 Speaker 3: about ten drinks a day and somehow functioned through this 833 00:41:08,640 --> 00:41:10,640 Speaker 3: recently well. But was drinking ten drinks a day, and 834 00:41:10,680 --> 00:41:13,600 Speaker 3: it sought treatment from physicians for this in a variety 835 00:41:13,600 --> 00:41:14,080 Speaker 3: of different ways. 836 00:41:14,120 --> 00:41:15,320 Speaker 2: Not a boich. You have been successful. 837 00:41:15,760 --> 00:41:19,120 Speaker 3: In her fiftyes, she suffered a stroke and the strength 838 00:41:19,480 --> 00:41:22,200 Speaker 3: was the stroke happened to land. It was a small stroke, 839 00:41:22,360 --> 00:41:25,960 Speaker 3: just in this little circuit, and she immediately found it 840 00:41:26,120 --> 00:41:28,520 Speaker 3: that she no longer had any desire or interest in 841 00:41:28,560 --> 00:41:31,680 Speaker 3: consuming alcohol, and the alcohol, the use that she'd been. 842 00:41:31,560 --> 00:41:33,440 Speaker 2: Trying to get her over for years just kind of 843 00:41:33,440 --> 00:41:33,920 Speaker 2: went away. 844 00:41:34,239 --> 00:41:36,120 Speaker 3: Other people with strokes in these areas, there are people 845 00:41:36,120 --> 00:41:39,200 Speaker 3: who have obsessed with compulsive disorder and have suffered this 846 00:41:39,280 --> 00:41:41,399 Speaker 3: is a weird thing that they had OCD for thirty 847 00:41:41,480 --> 00:41:42,960 Speaker 3: or forty years, and then one day they have a 848 00:41:42,960 --> 00:41:45,560 Speaker 3: stroke in their old age and the OCD goes away. 849 00:41:45,920 --> 00:41:50,839 Speaker 3: So yeah, So there are situations where this circuit gets 850 00:41:50,840 --> 00:41:53,080 Speaker 3: stuck in a feedback loop and the best thing you 851 00:41:53,120 --> 00:41:54,719 Speaker 3: can do here function is to just get out of 852 00:41:54,719 --> 00:41:58,080 Speaker 3: the feedback loop. Now, losing the circuit altogether is pretty drastic, right, 853 00:41:58,120 --> 00:42:00,279 Speaker 3: That's what we'd rather do is just turn it down 854 00:42:00,280 --> 00:42:03,000 Speaker 3: a little bit, and TMS can be used to do that. 855 00:42:03,520 --> 00:42:06,720 Speaker 3: Back in around twenty sixteen seventeen, I had a patient 856 00:42:06,719 --> 00:42:10,040 Speaker 3: who had come for TMS, and we tried the standard 857 00:42:10,320 --> 00:42:12,960 Speaker 3: TMS of one of these salience network cress and we 858 00:42:13,040 --> 00:42:16,000 Speaker 3: didn't get anywhere. So then we tried another salience network 859 00:42:16,000 --> 00:42:18,080 Speaker 3: cretion and for reasons you know and I've described, that 860 00:42:18,080 --> 00:42:20,680 Speaker 3: didn't do much either. And then she said, well, please, 861 00:42:20,719 --> 00:42:22,960 Speaker 3: I please try something else because I you know, the 862 00:42:23,000 --> 00:42:25,520 Speaker 3: next step normally would have been to go to electroconvulsive 863 00:42:25,560 --> 00:42:28,040 Speaker 3: therapy or shock therapy, and she really didn't want to 864 00:42:28,040 --> 00:42:30,080 Speaker 3: do that. So I said, well, there is this other 865 00:42:30,160 --> 00:42:34,640 Speaker 3: area that's been tried in OCD, and you don't have OCD, 866 00:42:34,760 --> 00:42:37,200 Speaker 3: but you do have a kind of depression that reminds 867 00:42:37,239 --> 00:42:39,600 Speaker 3: us of OCD because you just kind of get obsessed 868 00:42:39,640 --> 00:42:43,440 Speaker 3: with the same negative things about yourself. And when you 869 00:42:43,480 --> 00:42:45,680 Speaker 3: described me what your depression is like, it sounds almost 870 00:42:45,719 --> 00:42:48,759 Speaker 3: like an ocd ish flavor of depression. So if you will, 871 00:42:49,000 --> 00:42:50,799 Speaker 3: like you can come in and I'll give you this 872 00:42:50,920 --> 00:42:53,239 Speaker 3: treatment which has been used for OCD, and we'll say, 873 00:42:53,239 --> 00:42:56,760 Speaker 3: maybe let's see if your OCD ish depression gets somewhere. 874 00:42:57,040 --> 00:42:59,800 Speaker 3: And it was a complete remission. We also had scans 875 00:42:59,840 --> 00:43:02,040 Speaker 3: on her and we were able to show that normally 876 00:43:02,080 --> 00:43:05,239 Speaker 3: when we do TMS, we strengthen this salience network, and 877 00:43:05,280 --> 00:43:07,120 Speaker 3: you can see this connection strengthened. 878 00:43:07,440 --> 00:43:08,000 Speaker 2: In her case. 879 00:43:08,040 --> 00:43:10,560 Speaker 3: We scanned her before and after, and when she got better, 880 00:43:10,600 --> 00:43:13,239 Speaker 3: it had nothing to do with the salience network. Instead, 881 00:43:13,320 --> 00:43:17,319 Speaker 3: we had suppressed the over connection between this orbit of 882 00:43:17,320 --> 00:43:20,520 Speaker 3: frontal region and its little loop of activity down into 883 00:43:20,560 --> 00:43:21,520 Speaker 3: the reward circuitry. 884 00:43:21,800 --> 00:43:23,440 Speaker 2: So what happened to her after was what was what 885 00:43:23,520 --> 00:43:24,359 Speaker 2: was it like for her? 886 00:43:24,440 --> 00:43:28,120 Speaker 3: What she said was that essentially she was now free 887 00:43:28,120 --> 00:43:31,759 Speaker 3: of ruminations. I'll give you, and we had other people 888 00:43:31,800 --> 00:43:33,319 Speaker 3: come and do it, So I'll give you a really 889 00:43:33,320 --> 00:43:36,120 Speaker 3: illustrative example of one person who had a little bit 890 00:43:36,160 --> 00:43:37,880 Speaker 3: of both. She had a bit of column AN and 891 00:43:37,880 --> 00:43:39,640 Speaker 3: a bit of COLUMNB. So not only did she have 892 00:43:39,680 --> 00:43:42,719 Speaker 3: a tendency to be really obsessive and self critical and ruminative, 893 00:43:43,000 --> 00:43:44,960 Speaker 3: but she also tended to be quite impulsive and a 894 00:43:44,960 --> 00:43:47,600 Speaker 3: bit ADHD like and had difficulty with the cognitive control. 895 00:43:47,680 --> 00:43:48,800 Speaker 2: So she really struggled. 896 00:43:49,800 --> 00:43:51,760 Speaker 3: And she came to us from the eating sort of program, 897 00:43:51,840 --> 00:43:54,799 Speaker 3: and she bring she had blimior nervosa, so she would 898 00:43:54,800 --> 00:43:56,520 Speaker 3: spend a couple of hours a day binge eating and 899 00:43:56,520 --> 00:43:59,359 Speaker 3: then purshing it up and binge eating, and pershing. She 900 00:43:59,440 --> 00:44:01,640 Speaker 3: also had a lot of intrusive thoughts about her body 901 00:44:01,640 --> 00:44:05,040 Speaker 3: image and negative body thoughts. She had PTSD symptoms. She 902 00:44:05,080 --> 00:44:07,319 Speaker 3: had a lot of different things. So we gave her 903 00:44:07,360 --> 00:44:11,000 Speaker 3: the standard TMS and her depression scores went down by 904 00:44:11,000 --> 00:44:14,520 Speaker 3: about half, and she said, well, this is really interesting, 905 00:44:14,560 --> 00:44:17,600 Speaker 3: Like I feel somewhat better, like I noticed, like I'm 906 00:44:17,640 --> 00:44:20,640 Speaker 3: feeling less anxious and less depressed. And you certainly helped 907 00:44:20,680 --> 00:44:23,000 Speaker 3: me with my bolimia because I haven't had any urges 908 00:44:23,040 --> 00:44:25,359 Speaker 3: to beings or pursed, like those impulses are just gone. 909 00:44:26,080 --> 00:44:29,000 Speaker 3: But I still think about suicide every day, and I 910 00:44:29,000 --> 00:44:31,799 Speaker 3: still think about how horrible my body looks every day, 911 00:44:32,000 --> 00:44:36,080 Speaker 3: and I can't enjoy anything. And so we talked about 912 00:44:36,120 --> 00:44:37,920 Speaker 3: it a bit. And when I heard about these obsessions, 913 00:44:37,960 --> 00:44:40,520 Speaker 3: I said, well, you know, we could try going to 914 00:44:40,600 --> 00:44:43,439 Speaker 3: this other area that's typically an OCD area and see 915 00:44:43,440 --> 00:44:45,840 Speaker 3: if these obsessive thoughts you have about body image and 916 00:44:45,840 --> 00:44:48,200 Speaker 3: suicide and so on, let's see what that does. Because 917 00:44:48,200 --> 00:44:50,839 Speaker 3: a couple of other patients have been helped by it. 918 00:44:50,840 --> 00:44:52,160 Speaker 3: It was a while before we could get her in. 919 00:44:52,239 --> 00:44:54,960 Speaker 3: The clinic had a lineup, so we treated her and 920 00:44:54,960 --> 00:44:57,719 Speaker 3: then she came back in. This was lovely about She 921 00:44:57,840 --> 00:44:59,359 Speaker 3: came in and I asked her how she was doing, 922 00:44:59,360 --> 00:45:01,319 Speaker 3: and her scores down to the single dishits she was 923 00:45:01,320 --> 00:45:04,040 Speaker 3: doing really, really well. And I asked her, but what 924 00:45:04,120 --> 00:45:05,960 Speaker 3: was it like? And she said, well, I'll tell you 925 00:45:05,960 --> 00:45:08,680 Speaker 3: what I noticed. It was this past weekend. I was 926 00:45:08,719 --> 00:45:10,759 Speaker 3: playing with my niece and nephew, and I noticed that 927 00:45:10,800 --> 00:45:13,800 Speaker 3: I was smiling, and I noticed I was feeling pleasure, 928 00:45:14,000 --> 00:45:16,520 Speaker 3: like joy, which is weird. I hadn't felt that in 929 00:45:16,560 --> 00:45:18,880 Speaker 3: twenty years. And then I thought about it, and I 930 00:45:18,920 --> 00:45:21,440 Speaker 3: realized I actually hadn't thought about suicide all day, and 931 00:45:21,480 --> 00:45:23,359 Speaker 3: that hasn't happened for twenty And I realized I hadn't 932 00:45:23,360 --> 00:45:26,560 Speaker 3: thought about suicide for days, which hasn't happened. 933 00:45:26,719 --> 00:45:27,919 Speaker 2: I was able to enjoy things. 934 00:45:27,960 --> 00:45:30,359 Speaker 3: And then I realized I'd eaten a hamburger four days ago, 935 00:45:30,680 --> 00:45:32,319 Speaker 3: and normally i'd still be thinking about that. 936 00:45:32,280 --> 00:45:36,480 Speaker 2: Hamburger, regret about you, regret exactly. 937 00:45:36,800 --> 00:45:38,759 Speaker 3: I'd still be thinking like, why did you do that you? 938 00:45:39,480 --> 00:45:42,440 Speaker 3: And I realized that I just wasn't worried about the burger. 939 00:45:42,880 --> 00:45:44,960 Speaker 3: I'd eaten it, and yeah, I was a little upset 940 00:45:44,960 --> 00:45:47,360 Speaker 3: about it, but then I just wasn't thinking about it anymore. 941 00:45:47,600 --> 00:45:50,800 Speaker 3: But this was three or four months after her original treatment. 942 00:45:50,840 --> 00:45:52,400 Speaker 3: She said, but could I come back and have the 943 00:45:52,440 --> 00:45:54,640 Speaker 3: previous one again, because I'm starting to get back into 944 00:45:54,680 --> 00:45:57,319 Speaker 3: my binging and pershing behavior. That's that part is coming 945 00:45:57,360 --> 00:45:59,919 Speaker 3: back again. So you can see it what we would 946 00:46:00,280 --> 00:46:04,960 Speaker 3: in neuropsychology, a double dissociation, where treatment of one circuit 947 00:46:05,040 --> 00:46:07,720 Speaker 3: is helping with the person's impulses and their cognitive control. 948 00:46:07,840 --> 00:46:10,719 Speaker 3: And after treatment there she felt a stronger sense of 949 00:46:10,760 --> 00:46:13,800 Speaker 3: agency of self control with this first set of areas 950 00:46:13,800 --> 00:46:14,880 Speaker 3: around this alience network. 951 00:46:15,200 --> 00:46:16,120 Speaker 2: With the second set of. 952 00:46:16,120 --> 00:46:19,440 Speaker 3: Areas, she was feeling freedom from being trapped in a 953 00:46:19,480 --> 00:46:22,840 Speaker 3: circle of rumination on negative thoughts. But as the first 954 00:46:22,920 --> 00:46:26,120 Speaker 3: one wore off, she was losing that control piece. And 955 00:46:26,160 --> 00:46:28,920 Speaker 3: that highlights the two elements of resilience that come from this. 956 00:46:29,000 --> 00:46:31,880 Speaker 3: That what the ingredients of resilience seed be these two circuits. 957 00:46:31,920 --> 00:46:35,279 Speaker 3: Number one, having more self control or agency or a 958 00:46:35,320 --> 00:46:37,760 Speaker 3: sense of will to snap out of things or control 959 00:46:37,800 --> 00:46:41,279 Speaker 3: what you're thinking about. And number two, the ability to 960 00:46:41,400 --> 00:46:43,480 Speaker 3: not get stuck in a circle of rumination on the 961 00:46:43,480 --> 00:46:46,239 Speaker 3: same stuff, the ability to exit that circle. If you 962 00:46:46,320 --> 00:46:48,040 Speaker 3: have those two things, you're resilient. 963 00:46:49,000 --> 00:46:53,399 Speaker 1: So cut to a quarter century from now when this 964 00:46:53,440 --> 00:46:57,359 Speaker 1: is all very well worked out and every shopping mall 965 00:46:57,520 --> 00:47:01,160 Speaker 1: has a TMS clinic that you can walk into and. 966 00:47:01,120 --> 00:47:01,839 Speaker 2: I hope are there soon. 967 00:47:01,920 --> 00:47:06,800 Speaker 1: Yeah, Okay, The question is how will people know whether 968 00:47:07,840 --> 00:47:10,319 Speaker 1: they should go in and get this stream. It's like 969 00:47:10,360 --> 00:47:12,200 Speaker 1: it's like doing a tune up on your car. But 970 00:47:12,320 --> 00:47:14,680 Speaker 1: how do you know, you know, is there some variety 971 00:47:14,800 --> 00:47:19,879 Speaker 1: that would be useful to have in our society. How 972 00:47:19,880 --> 00:47:22,160 Speaker 1: do you know when you should get it at what level? 973 00:47:22,280 --> 00:47:25,120 Speaker 3: Yeah, it's a really interesting question, particularly because TMS is 974 00:47:25,120 --> 00:47:27,799 Speaker 3: a technology, so it gets better, it gets faster, it 975 00:47:27,800 --> 00:47:30,720 Speaker 3: gets cheaper over time. So you know, it's the example 976 00:47:30,760 --> 00:47:32,680 Speaker 3: of you know, when I was a kid, we talked 977 00:47:32,680 --> 00:47:35,040 Speaker 3: about flying to like space tourists who would go up 978 00:47:35,040 --> 00:47:37,399 Speaker 3: to flying space hotels, and that hasn't happened yet because 979 00:47:37,400 --> 00:47:39,040 Speaker 3: the cost of flying a space would have to come 980 00:47:39,080 --> 00:47:41,160 Speaker 3: down a lot before most of us can afford to 981 00:47:41,200 --> 00:47:44,800 Speaker 3: do that. And likewise, TMS presently is still pretty expensive. 982 00:47:44,840 --> 00:47:46,320 Speaker 3: But you know, the costs are coming down and the 983 00:47:46,360 --> 00:47:49,200 Speaker 3: availability is going up, and so the threshold for and 984 00:47:49,280 --> 00:47:52,960 Speaker 3: TMS happens to have an excellent safety profile, So the 985 00:47:53,040 --> 00:47:55,440 Speaker 3: question would become of when to go and get TMS. 986 00:47:55,560 --> 00:47:59,640 Speaker 3: Right now, it is an FDA cleared technique, and it 987 00:47:59,719 --> 00:48:02,080 Speaker 3: is the FDA is the cleared to be a prescription treatment, 988 00:48:02,160 --> 00:48:04,440 Speaker 3: so one one does go to a physician and obtain 989 00:48:04,480 --> 00:48:06,800 Speaker 3: a prescription to get TMS. 990 00:48:07,520 --> 00:48:08,000 Speaker 2: And in the. 991 00:48:08,000 --> 00:48:11,120 Speaker 3: Past, most insurers and pairs would require people to have 992 00:48:11,200 --> 00:48:13,600 Speaker 3: tried three or four or five or six different medications 993 00:48:13,600 --> 00:48:16,319 Speaker 3: before they often four medications or more before they were 994 00:48:16,840 --> 00:48:19,800 Speaker 3: allowed to apply for coverage for TMS. Now those numbers 995 00:48:19,800 --> 00:48:22,359 Speaker 3: are coming down and people are able to go earlier on. 996 00:48:23,520 --> 00:48:28,520 Speaker 3: So I think what we'll see is that it may 997 00:48:28,600 --> 00:48:32,120 Speaker 3: be that you'll be able to go for TMS to 998 00:48:32,280 --> 00:48:35,520 Speaker 3: enhance your functional capacity. Just knowing that we have these 999 00:48:35,520 --> 00:48:39,000 Speaker 3: two target circuits, people will be able to go in and. 1000 00:48:38,760 --> 00:48:40,800 Speaker 2: Across a wide variety of disorders. 1001 00:48:40,800 --> 00:48:43,200 Speaker 3: So at the moment, TMS is FDA cleared in depression, 1002 00:48:43,239 --> 00:48:46,200 Speaker 3: it's FDA cleared in OCD, and in chronic pain a 1003 00:48:46,200 --> 00:48:48,960 Speaker 3: couple of other conditions. But what might happen is it 1004 00:48:49,040 --> 00:48:51,640 Speaker 3: might be cleared across a wide basket of different conditions. 1005 00:48:51,680 --> 00:48:54,719 Speaker 3: And because the TMS really isn't what's interesting is we 1006 00:48:54,840 --> 00:48:56,760 Speaker 3: discovered the TMS isn't treating the depression. 1007 00:48:57,160 --> 00:48:58,960 Speaker 2: It's indirectly treating that by just. 1008 00:48:59,000 --> 00:49:03,040 Speaker 3: Generally enhancing your self control and allowing you to not 1009 00:49:03,040 --> 00:49:05,200 Speaker 3: get stuck in rumination. And that turns out to be 1010 00:49:05,280 --> 00:49:07,400 Speaker 3: useful not just for depression, but for lots of things. 1011 00:49:07,719 --> 00:49:10,759 Speaker 3: So where I hope we end up in hopefully a 1012 00:49:10,800 --> 00:49:12,920 Speaker 3: lot less than twenty five years, maybe in five years, 1013 00:49:13,800 --> 00:49:16,120 Speaker 3: would be in a situation where people can come in 1014 00:49:16,320 --> 00:49:20,040 Speaker 3: across a wide variety of conditions and maybe not waiting 1015 00:49:20,080 --> 00:49:22,520 Speaker 3: until they're extremely severe and until they've tried lots of 1016 00:49:22,560 --> 00:49:24,799 Speaker 3: other things. But you know, there may even be a 1017 00:49:24,800 --> 00:49:26,960 Speaker 3: world where you know, even and this is one thing 1018 00:49:27,000 --> 00:49:30,120 Speaker 3: people are working on, is even before going to medications, 1019 00:49:30,120 --> 00:49:32,360 Speaker 3: where people might be able to go and pursue this 1020 00:49:32,400 --> 00:49:35,960 Speaker 3: treatment right away. As you know, So when a person 1021 00:49:36,000 --> 00:49:39,640 Speaker 3: first starts to realize that they're encountering significant difficulty functioning 1022 00:49:39,719 --> 00:49:42,239 Speaker 3: because of the severity of their anxiety or depression or 1023 00:49:42,239 --> 00:49:44,439 Speaker 3: whatever it be, that they can go in and get 1024 00:49:44,560 --> 00:49:46,200 Speaker 3: essentially a top up of resilience. 1025 00:49:47,640 --> 00:49:48,879 Speaker 2: The thing that we all wish we had. 1026 00:49:49,440 --> 00:49:51,640 Speaker 3: That comes back to a dinner conversation we had ten 1027 00:49:51,719 --> 00:49:54,200 Speaker 3: years ago where I was sitting with some friends and 1028 00:49:54,360 --> 00:49:57,440 Speaker 3: as a dinner conversation starter, we said, okay, let's go 1029 00:49:57,440 --> 00:50:00,160 Speaker 3: around the room and let's say you had the abilit 1030 00:50:00,280 --> 00:50:03,240 Speaker 3: to just rub a magic lamp and a genie would 1031 00:50:03,360 --> 00:50:05,880 Speaker 3: would you could say one word and then everyone in 1032 00:50:05,920 --> 00:50:06,640 Speaker 3: the world would. 1033 00:50:06,440 --> 00:50:08,760 Speaker 2: Be gifted that thing. So what would you? 1034 00:50:08,800 --> 00:50:10,560 Speaker 3: And we all went around the table, and the one 1035 00:50:10,600 --> 00:50:13,320 Speaker 3: I chose was happened to be resilience. I said, the 1036 00:50:13,400 --> 00:50:14,920 Speaker 3: world would just run better if we could all have 1037 00:50:14,960 --> 00:50:17,080 Speaker 3: a little bit more resilience. So I would love to 1038 00:50:17,080 --> 00:50:19,040 Speaker 3: get to a world where we just generally have this 1039 00:50:19,120 --> 00:50:23,359 Speaker 3: treatment that enhances one's ability to be resilient, And if 1040 00:50:23,360 --> 00:50:25,799 Speaker 3: we could get that out to everybody with you know, 1041 00:50:25,880 --> 00:50:26,960 Speaker 3: a relatively short. 1042 00:50:26,719 --> 00:50:28,320 Speaker 2: Treatment, not that we shouldn't. 1043 00:50:28,360 --> 00:50:30,839 Speaker 3: Also, you know, people can go and do mindfulness and 1044 00:50:30,880 --> 00:50:33,080 Speaker 3: cognitive therapy and all these other things, and that. 1045 00:50:33,280 --> 00:50:35,200 Speaker 2: That takes time and skill set. 1046 00:50:35,239 --> 00:50:37,440 Speaker 3: It's it's like piano lessons, You've got to put putting 1047 00:50:37,440 --> 00:50:40,000 Speaker 3: your time and your hours to do it. But I 1048 00:50:40,000 --> 00:50:42,359 Speaker 3: think those piano lessons will go faster for people if 1049 00:50:42,400 --> 00:50:46,319 Speaker 3: we can use if we can drop on their inner strengths. 1050 00:50:46,760 --> 00:50:49,120 Speaker 3: Let's pull out your maximum because we all have these 1051 00:50:49,120 --> 00:50:53,399 Speaker 3: circuits and we all have neuroplasticity. So every human being 1052 00:50:53,480 --> 00:50:56,360 Speaker 3: has every human beings brain, as you've discussed many times, 1053 00:50:56,400 --> 00:50:59,320 Speaker 3: has the ability to rewire and change itself, and every 1054 00:50:59,360 --> 00:51:02,160 Speaker 3: human being has somewhere in though theo's circuits that allow 1055 00:51:02,239 --> 00:51:05,240 Speaker 3: us to do cognitive control and to escape from rumination 1056 00:51:05,320 --> 00:51:07,719 Speaker 3: and so on. These are all innercapacities that are hit 1057 00:51:07,920 --> 00:51:09,640 Speaker 3: that are within all of us, and some of them 1058 00:51:09,680 --> 00:51:12,200 Speaker 3: it's on the surface the highly resilient people, but in 1059 00:51:12,239 --> 00:51:14,879 Speaker 3: people who aren't feeling resilient, where people do have these 1060 00:51:14,920 --> 00:51:18,120 Speaker 3: access one disorders, it's not that they don't have that capacity, 1061 00:51:18,120 --> 00:51:21,120 Speaker 3: it's just it's latent, it's hiding, and we're now having 1062 00:51:21,160 --> 00:51:26,520 Speaker 3: a capacity by combining targeted brain stimulation with neuroplasticity enhancement, 1063 00:51:27,040 --> 00:51:29,600 Speaker 3: we can bring out the person's inner strengths. And I 1064 00:51:29,640 --> 00:51:33,000 Speaker 3: think that's something that is just would be I wish 1065 00:51:33,040 --> 00:51:34,920 Speaker 3: if we could have everybody listening to is just no 1066 00:51:35,000 --> 00:51:37,439 Speaker 3: one thing, is that all of us have these inner 1067 00:51:37,440 --> 00:51:40,120 Speaker 3: strengths inside us, and some of us has been hidden 1068 00:51:40,360 --> 00:51:43,279 Speaker 3: en dormant for a long time. But I think every 1069 00:51:43,320 --> 00:51:45,680 Speaker 3: one of us those abilities are there and we can 1070 00:51:45,760 --> 00:51:46,720 Speaker 3: bring them to the surface. 1071 00:51:49,880 --> 00:51:52,560 Speaker 1: That's beautiful. Let me just ask one last question I 1072 00:51:52,640 --> 00:51:57,520 Speaker 1: wanted to come back on, which is the influence of 1073 00:51:57,560 --> 00:52:00,000 Speaker 1: our social lives on resilience. 1074 00:52:00,920 --> 00:52:03,799 Speaker 3: That's beautiful and I'm really glad you brought that up, 1075 00:52:03,920 --> 00:52:06,239 Speaker 3: because up until now, everything we've been talking about with 1076 00:52:06,360 --> 00:52:10,520 Speaker 3: resilience is are like are like. The human atom he's 1077 00:52:10,520 --> 00:52:13,520 Speaker 3: just started for individuals in isolation is one human brain 1078 00:52:13,719 --> 00:52:16,000 Speaker 3: just by itself, a bunch of circuits inside a skull. 1079 00:52:16,600 --> 00:52:18,799 Speaker 3: But we don't live as little atoms. No, no human 1080 00:52:18,840 --> 00:52:19,480 Speaker 3: as an island. 1081 00:52:19,560 --> 00:52:20,040 Speaker 2: We all have. 1082 00:52:20,520 --> 00:52:23,919 Speaker 3: We live within a broad social fabric. And I think 1083 00:52:23,960 --> 00:52:26,439 Speaker 3: you can delve into any number of beautify written books 1084 00:52:26,480 --> 00:52:28,680 Speaker 3: on resilience, we'll talk about one of the greatest and 1085 00:52:28,719 --> 00:52:32,800 Speaker 3: most important things supporting a person's resilience is the social 1086 00:52:32,840 --> 00:52:36,480 Speaker 3: supports and fabric that they have around them. Most challenges 1087 00:52:36,680 --> 00:52:38,960 Speaker 3: can be faced if they're not faced alone. 1088 00:52:40,600 --> 00:52:41,320 Speaker 2: I think most of it. 1089 00:52:41,600 --> 00:52:43,160 Speaker 3: I talked to a colleague of mind, and he talked 1090 00:52:43,200 --> 00:52:45,600 Speaker 3: about how his favorite part of medical training was actually 1091 00:52:45,640 --> 00:52:47,920 Speaker 3: in medical school, which some people see is the toughest part. 1092 00:52:48,040 --> 00:52:49,840 Speaker 3: So but the thing is, I had these two buddies, 1093 00:52:50,200 --> 00:52:52,080 Speaker 3: and the three of us we did all our studying together. 1094 00:52:52,080 --> 00:52:53,960 Speaker 3: We worked through it was all we were these comrades, 1095 00:52:53,960 --> 00:52:55,560 Speaker 3: and we felt like when we faced the world, we 1096 00:52:55,560 --> 00:52:58,200 Speaker 3: were unstoppable. Like you know, it's a very stressful thing 1097 00:52:58,239 --> 00:53:00,000 Speaker 3: going through training in medical school, but as long as 1098 00:53:00,200 --> 00:53:04,160 Speaker 3: I have my two buddies with me, we could face anything. Yeah, 1099 00:53:04,200 --> 00:53:05,960 Speaker 3: and I think a lot of us have that experience. 1100 00:53:06,080 --> 00:53:08,600 Speaker 3: So there's been is, you know, a tremendous amount of 1101 00:53:08,600 --> 00:53:11,120 Speaker 3: research done on the importance of social fabric and social 1102 00:53:11,160 --> 00:53:12,880 Speaker 3: supports and a strong social network. 1103 00:53:12,920 --> 00:53:14,960 Speaker 1: Well, what would you recommend for people? What do you 1104 00:53:15,040 --> 00:53:18,640 Speaker 1: recommend for people in terms of building a social life. 1105 00:53:18,760 --> 00:53:20,279 Speaker 2: Well, it's I mean, it's tricky. 1106 00:53:20,560 --> 00:53:22,200 Speaker 3: I think there's certainly been a shift over the last 1107 00:53:22,280 --> 00:53:24,719 Speaker 3: decade in terms of, you know, how people spend their time, 1108 00:53:24,760 --> 00:53:27,080 Speaker 3: and if everybody else is just locked away on, you know, 1109 00:53:27,200 --> 00:53:30,239 Speaker 3: in solitary activities of one type or another, then it's 1110 00:53:30,280 --> 00:53:31,879 Speaker 3: harder and harder to go out there and find people 1111 00:53:31,920 --> 00:53:35,440 Speaker 3: to do social things with. But I find that the 1112 00:53:35,440 --> 00:53:39,440 Speaker 3: way people build social communities is often either through mutual 1113 00:53:39,480 --> 00:53:43,040 Speaker 3: connections or through mutual activities. So you can meet friends 1114 00:53:43,040 --> 00:53:45,839 Speaker 3: through other friends, and you can and so friends are 1115 00:53:45,840 --> 00:53:48,839 Speaker 3: good at introducing other friends, and activities are also good 1116 00:53:48,920 --> 00:53:50,399 Speaker 3: at introducing and connecting people. 1117 00:53:50,480 --> 00:53:50,800 Speaker 2: Together. 1118 00:53:51,640 --> 00:53:53,520 Speaker 3: So one way you can kind of get two birds 1119 00:53:53,520 --> 00:53:56,760 Speaker 3: of one stone is you know, running clubs have become 1120 00:53:56,800 --> 00:53:59,720 Speaker 3: incredibly popular, just to take one random example of ways 1121 00:53:59,719 --> 00:54:02,280 Speaker 3: that people have decided to sort of quit dating apps 1122 00:54:02,280 --> 00:54:03,759 Speaker 3: and instead of just go out and go on these 1123 00:54:03,760 --> 00:54:05,839 Speaker 3: big running clubs. And this is how young singles are 1124 00:54:05,920 --> 00:54:07,920 Speaker 3: kind of meeting each other is by finding some kind 1125 00:54:07,920 --> 00:54:10,319 Speaker 3: of activity in common. But whether you fall into that 1126 00:54:10,360 --> 00:54:13,839 Speaker 3: category or not, I think there are I think a 1127 00:54:13,960 --> 00:54:16,040 Speaker 3: variety of different websites and so on out there, like 1128 00:54:16,120 --> 00:54:18,320 Speaker 3: meetup dot com is an old one that's been around forever. 1129 00:54:18,719 --> 00:54:20,319 Speaker 3: I thought it was quite clever, the idea that you 1130 00:54:20,520 --> 00:54:22,920 Speaker 3: just have various activities and people could connect over an 1131 00:54:22,960 --> 00:54:25,560 Speaker 3: activity or an interest that they had in common. So 1132 00:54:25,600 --> 00:54:28,080 Speaker 3: I think whether it's reaching out to a faith community 1133 00:54:28,080 --> 00:54:30,640 Speaker 3: if you're somebody who follows a particular faith, or whether 1134 00:54:30,640 --> 00:54:33,520 Speaker 3: it's an interest group, or whether it's a physical activity 1135 00:54:33,520 --> 00:54:37,120 Speaker 3: like exercise or running, I think finding activities to connect 1136 00:54:37,120 --> 00:54:40,080 Speaker 3: with other people who have that common interest is a 1137 00:54:40,200 --> 00:54:43,040 Speaker 3: really really great way of strengthening your connections with other people. 1138 00:54:43,120 --> 00:54:46,400 Speaker 2: Finding common purpose among cultures. 1139 00:54:48,040 --> 00:54:50,240 Speaker 3: It's interesting if you go read up on the culture 1140 00:54:50,239 --> 00:54:54,759 Speaker 3: of Okinawa Okinawa's for various is identify as one of 1141 00:54:54,800 --> 00:54:57,480 Speaker 3: these blue zones where people live unusually long and so on. 1142 00:54:57,719 --> 00:54:59,319 Speaker 3: But one of the interesting things that they talk about 1143 00:54:59,400 --> 00:55:03,000 Speaker 3: is the unusual psychological resilience of people in Okinawa and 1144 00:55:02,400 --> 00:55:07,120 Speaker 3: the concept of which I was introduced to recently. I'm 1145 00:55:07,239 --> 00:55:09,759 Speaker 3: probably going to say it wrong, but eke guy is 1146 00:55:09,800 --> 00:55:12,520 Speaker 3: a there's a word, eke guy. I'm probably going to 1147 00:55:12,600 --> 00:55:14,759 Speaker 3: butcher this, but as I understand it, it is the 1148 00:55:14,800 --> 00:55:16,960 Speaker 3: idea of having a purpose or a calling or a 1149 00:55:17,000 --> 00:55:20,960 Speaker 3: cause and part of the culture there is that you know. 1150 00:55:21,000 --> 00:55:23,160 Speaker 3: And it could be something incredibly small, it's like literally 1151 00:55:23,239 --> 00:55:25,320 Speaker 3: like breaking a beach and keeping it tidy, or it 1152 00:55:25,360 --> 00:55:27,319 Speaker 3: could be or it could be something lars like trying 1153 00:55:27,360 --> 00:55:30,600 Speaker 3: to save the world from a resilience deficit. 1154 00:55:30,600 --> 00:55:31,719 Speaker 2: It could be anything whatsoever. 1155 00:55:33,040 --> 00:55:37,919 Speaker 3: But the idea that part of resilience involves in making 1156 00:55:37,960 --> 00:55:39,840 Speaker 3: sure that your life is imbued with meaning and that 1157 00:55:39,920 --> 00:55:41,840 Speaker 3: you have some kind of compass or some kind of 1158 00:55:41,880 --> 00:55:44,200 Speaker 3: guidance to it. And so I think if you can 1159 00:55:44,200 --> 00:55:46,399 Speaker 3: find that activity that you choose with the people around 1160 00:55:46,480 --> 00:55:48,560 Speaker 3: you to be a meaningful activity, something you find that 1161 00:55:48,560 --> 00:55:50,919 Speaker 3: gives you purpose and meaning in life, that carries eke guy. 1162 00:55:51,440 --> 00:55:52,960 Speaker 3: And if on top of that it's not just a 1163 00:55:52,960 --> 00:55:54,839 Speaker 3: personal meaning, but if you can then use that as 1164 00:55:54,880 --> 00:55:58,160 Speaker 3: a nucleus to build a community of other people around 1165 00:55:58,160 --> 00:56:02,680 Speaker 3: that common purpose, there incredibly resilience to be had and 1166 00:56:02,880 --> 00:56:05,359 Speaker 3: being a member of a community of other people, all 1167 00:56:05,400 --> 00:56:08,160 Speaker 3: of whom are dedicated to a common and meaningful cause. 1168 00:56:09,000 --> 00:56:11,080 Speaker 3: And I think if you don't have access to a 1169 00:56:11,080 --> 00:56:13,279 Speaker 3: TMS machine, I think that's certainly the compass that I 1170 00:56:13,320 --> 00:56:14,040 Speaker 3: would lean into. 1171 00:56:18,719 --> 00:56:24,520 Speaker 1: That was my conversation with Jonathan Downer. So what is resilience. 1172 00:56:25,040 --> 00:56:28,600 Speaker 1: We've long thought about it as a psychological trait. We 1173 00:56:28,640 --> 00:56:33,640 Speaker 1: talked about grit or determination or optimism. But what today's 1174 00:56:33,680 --> 00:56:38,239 Speaker 1: conversation hopefully makes clear is that resilience has a physical 1175 00:56:38,280 --> 00:56:41,440 Speaker 1: footprint in the brain. It's not just about what you 1176 00:56:41,600 --> 00:56:45,719 Speaker 1: choose to think. It's about how your networks are operating. 1177 00:56:46,320 --> 00:56:51,719 Speaker 1: It involves a carefully orchestrated interplay between brain areas involved 1178 00:56:51,719 --> 00:56:55,120 Speaker 1: in emotion and reward and control and so on. And 1179 00:56:55,200 --> 00:57:01,080 Speaker 1: these brain networks can dip the balance between breaking down 1180 00:57:01,520 --> 00:57:04,319 Speaker 1: and bouncing back. And I think this is some of 1181 00:57:04,320 --> 00:57:09,080 Speaker 1: the most exciting and practical work happening in neuroscience. People 1182 00:57:09,080 --> 00:57:13,959 Speaker 1: are identifying these circuits and they are influencing them using 1183 00:57:14,040 --> 00:57:19,080 Speaker 1: tools like PMS, and this can, when it works, enhance 1184 00:57:19,200 --> 00:57:24,480 Speaker 1: a person's ability to function across a whole spectrum of disorders. 1185 00:57:25,120 --> 00:57:28,960 Speaker 1: And so one lesson that emerges is that resilience isn't 1186 00:57:29,000 --> 00:57:33,480 Speaker 1: just something we summon after disaster strikes. It's something we 1187 00:57:33,520 --> 00:57:37,200 Speaker 1: can build ahead of time. It's something we can cultivate 1188 00:57:37,280 --> 00:57:41,720 Speaker 1: in the brain like a form of mental infrastructure, one 1189 00:57:41,760 --> 00:57:45,640 Speaker 1: that helps us face whatever is coming down the pike next. 1190 00:57:46,440 --> 00:57:50,320 Speaker 1: And as our knowledge improves and the technology improves, this 1191 00:57:50,400 --> 00:57:54,760 Speaker 1: all may eventually lead to a paradigm shift in mental health. 1192 00:57:55,080 --> 00:57:59,400 Speaker 1: Instead of treating one disorder at a time, like depression 1193 00:57:59,520 --> 00:58:04,480 Speaker 1: or anxiety PTSD, what if we focused upstream, What if 1194 00:58:04,520 --> 00:58:09,160 Speaker 1: we try to increase resilience itself across the board. Of course, 1195 00:58:09,200 --> 00:58:13,280 Speaker 1: biology is only part of the story. Social support, culture, 1196 00:58:13,520 --> 00:58:18,360 Speaker 1: personal meaning. These are all powerful factors and addressable factors 1197 00:58:18,600 --> 00:58:22,080 Speaker 1: when we're thinking about resilience in our lives. But it's 1198 00:58:22,120 --> 00:58:25,800 Speaker 1: amazing to realize that even in the hardest moments, the 1199 00:58:25,880 --> 00:58:30,200 Speaker 1: exact state of the networks in your brain matters for 1200 00:58:30,320 --> 00:58:33,840 Speaker 1: the degree to which you can be an active participant 1201 00:58:33,880 --> 00:58:38,920 Speaker 1: in recovery. Maybe if we come to understand resilience in 1202 00:58:38,960 --> 00:58:42,919 Speaker 1: the brain and psychologically and socially, we can help more 1203 00:58:43,000 --> 00:58:46,440 Speaker 1: people to thrive.

Science is catching up to something that 1211 00:59:10,480 --> 00:59:13,080 Speaker 1: people have known in their bones for a long time. 1212 00:59:13,800 --> 00:59:18,160 Speaker 1: The mind can bend without breaking, and sometimes in that 1213 00:59:18,280 --> 00:59:22,840 Speaker 1: bending it gets stronger. So until next time, take care 1214 00:59:22,880 --> 00:59:25,840 Speaker 1: of your brain so you can take care of each other. 1215 00:59:29,560 --> 00:59:32,480 Speaker 1: Go to Eagleman dot com slash podcast for more information 1216 00:59:32,600 --> 00:59:36,680 Speaker 1: and to find further reading, and check out and subscribe 1217 00:59:36,680 --> 00:59:40,000 Speaker 1: to Inner Cosmos on YouTube for videos of each episode 1218 00:59:40,040 --> 00:59:43,920 Speaker 1: and to leave comments.
