    You Don't Get Through The Day Alone - Sharon Salzberg on DL Ep. 36

    Sharon Salzberg joins Richie Davidson and Cortland Dahl for a conversation about loving-kindness, connection, and the quiet ways our lives are supported by others. At a time when many people feel lonely, cut off, or pulled into habits of criticism and competition, Sharon offers a simple experiment: pause, notice who makes your life possible, and see what happens when appreciation becomes part of daily life. Sharon Salzberg is a meditation teacher, New York Times bestselling author, and co-founder of the Insight Meditation Society in Barre, Massachusetts. She has written fifteen books, including Lovingkindness and Real Happiness. Her upcoming workbook, Living Lovingkindness, is available for pre-order and will be released in January 2027. Enjoy!

I’m very honored and excited to be here with our two guests. Of course, I’m here with Richie Davidson, who many of you already know, one of the most well-known neuroscientists on the planet. And we’re here with a true icon of the world’s meditative tradition, Sharon Salzberg, who’s also a dear friend, and truly one of those people who, when the history books are written about the manifestation of these meditative traditions in the modern world, played an incredibly important role. Just before this started, we were all chatting, and Sharon, you were mentioning that this is the 50th anniversary of the Insight Meditation Society. IMS, as it’s commonly referred to, is certainly one of the first and one of the most important centers for Buddhist practice and meditation in the modern world. Sharon is one of the co-founders of IMS, back in the 1970s. It’s hard to believe it’s been 50 years. She has written some of the most well-known books in the meditation world. Loving-Kindness — she literally wrote the book on loving-kindness, and has been the main proponent of it as one of the main forms of meditation coming out of the Buddhist tradition, traditionally known as metta. She also has a podcast, Metta Hour, which both Richie and I have been on. And she’s written many other books, including her first children’s book, Kind Carl. Richie Davidson I read it to my six-year-old granddaughter, who loved it, absolutely loved it, and wanted more copies to give to all her friends. Cort Dahl And many, many other books — Real Life, Real Love, Real Happiness, a whole series. Loving-Kindness, the book I mentioned first, is really a modern classic. It was one of the first books I read back in the nineties when I was starting to meditate. So, Sharon, you’ve been an inspiration to so many of us — through your writing, through co-founding IMS, through your endless teaching all over the world. It’s an honor to have you. I thought we could start with a story I’ve heard a few times and always found moving: His Holiness the Dalai Lama visiting the United States for the first time, and your interactions with him. Let’s start there, and see where the conversation goes. (03:33) The Dalai Lama and the crutches Sharon Salzberg Sure. And I’m so happy and honored to be with the two of you, truly. We co-founded the retreat center — Jack Kornfield, Joseph Goldstein and I — in 1976. It’s in Barre, Massachusetts, about 40 minutes from Amherst. In 1979 we heard the Dalai Lama was coming to Amherst, so, being young and bold, we wrote a letter to his private office and said, maybe you’d like to visit us too. And to our amazement, we got a letter back saying, yes, he’ll come. It was an incredibly zooey day. We had sheriffs and people patrolling the roof with guns, the street blockaded. A very intense day. And I’d been in a car accident a few weeks before — I had a broken bone in my foot and was using crutches, which I was not very skilled with. So I was standing way at the back of about a hundred people. His car pulled up, he got out, and he did something I’ve seen him do many times since, but it was the first time. It’s almost like he has a kind of radar for who in a crowd is suffering the most, and that was me. He cut through a hundred people, took my hand, looked me in the eye, and said, what happened? Standing there in the back, I’d been thinking, I’m so stuck back here, this is terrible — I helped start this place, and here I am at the back. But if I go up front I’ll fall on my face, because I’m so bad with the crutches, so I’d better stay in the back. And he just dissolved that with that one gesture. It sort of redefined compassion for me, because he certainly couldn’t have made the injury not happen, or made me any better with the crutches. But that horrible feeling of being so alone, so unseen, so stuck in the back — it just dissolved. There’s another story from that visit, and there are many. We had a retreat going, about two weeks in, and the Dalai Lama asked to go into the meditation hall and give a talk. Then he asked for questions. A young man raised his hand and said, I’ve been meditating for about two weeks and I realize it’s not going to work for me. I can’t do it. I don’t have the capacity to grow or learn or get more loving or more mindful. I just can’t do it. And the Dalai Lama looked at him and said, well, you’re wrong. You’re just wrong. He went on to talk about buddha nature — one’s capacity, which it’s believed is never ever destroyed. A capacity for growth and understanding and change. It may be covered over, it may be hard to find, but it’s never ever destroyed. And the funny thing is, after the talk, all these people came up to me and said, the Dalai Lama shouldn’t have said that. That’s bad pedagogy. You should never tell anyone they’re wrong. But you know who got a huge amount out of it? The young man, for whom it was such an important message. You should have a little more faith in yourself, and in the possibility of change. Cort Dahl That’s so beautiful. The image of the Dalai Lama cutting through all those people — at a moment where most of us would be on autopilot, this is what you do in this situation, you shake hands and wave. And he didn’t. He was just utterly human, and could see beyond the dynamics. I’ve always found that story so beautiful. Richie Davidson I love that story too. I have this image of our detectors, our antenna, for suffering, that can actually be developed. And the Dalai Lama is such an extraordinary exemplar of that. Wherever suffering is occurring, he makes a beeline for it. Cort Dahl And the human element is something I really think about with you as a teacher. I was just having lunch with my wife, Kasumi. We’ve been together thirteen, fourteen years now. When we first met, she was about to go on a retreat with you — you were visiting Madison — one of her first retreats. You’ve been a huge influence in her life. Over lunch I said, I’m going to be talking to Sharon, what would you ask? And she said something that’s so true, something I’ve heard from many people and know from my own experience: you talk so candidly about your own experience, and the human experience, in a way that’s quite uncommon. Just being fully human and sharing your experience. Because it’s so easy to see someone at the front of the room teaching meditation and imagine, wow, they’ve got it all figured out, this perfect life — and here I am, a distracted, anxious mess. I think that’s one of the reasons your teachings resonate so deeply. With all these decades of working directly with people, hearing from thousands of them, what are the things that either trip us up — the common stumbling blocks early on — or the things that inspire and unlock us when we hear the right thing at the right time? (09:35) What actually trips people up Sharon Salzberg Well, I think we — including myself — bring some of our greatest patterns into the meditative process. Especially a kind of harsh self-criticism, which I’ve seen over and over. Even people in really difficult situations, really hard diagnoses, something hard to bear. Sometimes I listen and think, give yourself a break — this is hard, look what you’re going through. That’s one of the reasons I found loving-kindness practice, and the understanding that we can grow in other ways rather than punishing ourselves for our mistakes. We can move on. We can learn to begin again. There’s resilience there. I’ve found that a huge help for a lot of people. Somebody asked me the other day whether I wanted to teach Buddhism or better mental health. And I said, mental health is not that high right now. So many people feel broken and lonely and estranged and confused. Of course we always do to some degree, but it feels so exaggerated now, so emphasized. For people to have a sense of not being so alone, and caring about themselves and about one another, having a greater sense of community — that seems to be what we can offer these days. Cort Dahl That’s so helpful. Richie, any thoughts from you, having explored the same territory yourself, both personally and in your work? Richie Davidson In terms of the situation today, it really is true. I often say we’re all part of a grand experiment for whic

    Boredom is Where You Meet Your Mind; DL Ep.34 with Dr. Richie Davidson and Dr. Cortland Dahl

    We now live in a world where boredom is almost optional. The moment there is a gap in the day, we can reach for a device and instantly distract ourselves. In this episode of Dharma Lab, Dr. Richard Davidson and Dr. Cortland Dahl explore boredom and restlessness from both a scientific and contemplative perspective. Richie explains why boredom often brings us face to face with the “default mode” of the brain, the self-referential narrative we carry around about who we are. Cort reflects on the physical, restless energy of boredom, and how meditation can turn that discomfort into an object of curiosity. They also offer a simple and powerful tool to bring more awareness into our day: the next time we feel the urge to escape boredom, we can pause, notice the urge, and let that moment become a practice.

Cortland Dahl:We’re now living in a world where we just have such an easy escape hatch. We carry around these devices, and it’s so easy to distract ourselves that I feel like we’ve almost developed an incapacity to be bored. Richie Davidson:Our response to boredom, our relationship to boredom, has a lot to do with our comfort with our own mind. One of the things about boredom is that we tend to get bored when there’s not stuff for us to do. And when there’s not stuff for us to do, we are confronted inevitably by our own mind. 00:00:58 – Why boredom matters Cortland:Hello everyone. Welcome to Dharma Lab. I’m here with my dear friend and colleague, Dr. Richard Davidson, one of the world’s eminent neuroscientists, and I’m Cortland Dahl. Today we’re going to talk about something I think probably everybody experiences, and maybe experiences a lot, which is boredom and restlessness. 00:01:21 – “I could not sit still” Cortland:I have such vivid memories of this. If we had a normal distribution of where people fall and how easily bored they are, I’m pretty sure I would have been an outlier. I was so easily bored as a kid. I was one of those kids who just could not sit still. I have vivid memories, especially of summer afternoons, sitting at home and desperately trying to call my friends to see if anybody wanted to hang out. There was nothing on TV. This was back in the days before you could get everything on demand, just boring daytime TV shows. And I remember this feeling of crawling out of my skin. I literally could not sit there. We had no mobile phones. This was long before the iPhone and smartphones. But I would have done anything to have had something like that. Now it’s kind of amazing. After years of meditation, I would say if one thing has changed in my life, it’s my relationship to boredom. I kind of feel like I’m immune to boredom now. There’s a whole long practice history with that. But I thought we could start by talking about boredom because we’re now living in a world where we have such an easy escape hatch. We carry around these devices, and it’s so easy to distract ourselves that I feel like we’ve almost developed an incapacity to be bored, to just sit with that. So maybe we could talk about it from a scientific perspective. We can both share our personal experiences. But let me kick it over to you, Richie, and see if you have any opening thoughts. Then we can dive into it more deeply. 00:03:34 – Boredom and comfort with our own mind Richie:I think boredom is an interesting topic. Cortland:It is. That’s the weird thing. It’s strangely interesting. Boredom is not boring. Richie:Yeah, it is strangely interesting. I think it’s a phenomenon that has been deeply impacted by changes in the fabric of our society, by the development of technology and so forth. And I think boredom, our response to boredom, our relationship to boredom, has a lot to do with our comfort with our own mind. One of the things about boredom is that we tend to get bored when there’s not stuff for us to do. And when there’s not stuff for us to do, we are confronted inevitably by our own mind. That is the one thing we can’t get rid of. People try, with drugs and other ways to dull the mind, but under most circumstances we have our minds. 00:04:19 – The default mode network Richie:From a neuroscientific perspective, we know that when a person is not engaged in a demanding activity that really requires their mental resources, what is active is a mode of brain function that we call the default mode. The default mode is mostly associated with self-referential thought. By self-referential thought, we mean the narrative we tell ourselves about who we are and all the things associated with that. And for a lot of people, that’s uncomfortable. 00:05:01 – Why awareness can feel uncomfortable at first Richie:We have data from work we’ve done using our Healthy Minds program with beginning meditators who’ve never meditated before. We often see that after the first week or so of cultivating awareness, they actually become more anxious. They report more anxiety. We think it’s not that they’re actually experiencing more anxiety, but that they’re noticing what’s going on in their mind. And what’s going on in their mind is often quite chaotic. Simply becoming more aware of it makes them more anxious, or they perceive their anxiety more accurately for the first time. And so they report higher scores more accurately. So I think one of the reasons people try to find strategies to get rid of boredom is because the chaotic nature of their own mind is uncomfortable. I actually think this is why people engage in certain kinds of leisure activities that are cognitively demanding, but that don’t serve any other function other than being interesting leisure activities. For example, doing crossword puzzles or Sudoku. There are a lot of people who spend a lot of time doing those things, and people report that they enjoy it. I think they enjoy it because it temporarily blocks the default mode. It temporarily engages other parts of their mind, so they’re not aware of the self-referential activity. They’re not aware of the narrative going on in the background. 00:06:52 – The body’s role in restlessness Cortland:I’m curious about one thing I’d love to unpack from a scientific point of view: the relationship between these brain networks, specifically the default mode network that you talked about, and the rest of the nervous system. If I think back to my teenage self sitting on the couch, which to me is the most intensely bored I can remember feeling in my life, I think at that time I was completely oblivious to what was going on in my mind. When I remember that, I don’t remember the thought activity. Now, having meditated, I’m sure it was going on, but I just didn’t know how to attend to what was going on in my mind. But what I do remember is the physicality. There was almost this charge of restless energy. I needed to release the energy, and it just had nowhere to go. You’re kind of just this ball of energy, and yet it’s like you’re trying to constrain a ball of energy that’s trying to get out, but there’s no release for it. I’m imagining there are all sorts of things going on in the brain and the nervous system. It points to the relationship between thought activity, which can be completely subterranean at times. We’re not even really aware of all the thought activity, and yet it can have this bidirectional relationship with emotional experiences and physical experiences. I wonder if you could speak to that a little bit too, because I think the felt experience of boredom is often a very physical experience. 00:08:36 – Richie’s childhood outlet: the bicycle Richie:Yeah, that’s so interesting. When I think back to my childhood, during those periods I got on my bicycle. Cortland:That’s what I should have done, probably. Richie:I developed a lifelong habit, which I still have, of riding my bicycle. I grew up in New York City, in Brooklyn, and for me my bicycle was liberating. I rode all over Brooklyn. I rode over the Brooklyn Bridge to Manhattan all the time. This was before I had permission to go on the subway by myself, but I could go on my bicycle. My parents didn’t really know where I was, and I just went. I explored all over. That was important for me. I also felt a kind of somatic restlessness, but I was able to deal with it through physical activity. 00:09:38 – Restlessness, the body, and the brain Richie:Getting back to the essence of your question, I think it is certainly the case, and we’re learning more and more about this now, that there is bidirectional communication between the brain and the body. We know there are certain networks in the brain that communicate with the body. Activity in the brain will be expressed in part through the body, through changes in both the autonomic nervous system and the skeletal muscular system, through muscle tension and things of that sort. One of the signs of anxiety is increased muscle

    DL Ep. 33: The Left Brain / Right Brain Myth with Dr. Richie Davidson and Dr. Cortland Dahl

    In this episode, Richie and Cort continue their conversation on brain asymmetry by revisiting one of the most popular neuroscience ideas of the 1990s: the divide between the “left brain” and the “right brain.” Was the right hemisphere really the creative side of the brain, and the left hemisphere the logical one? Richie explains where that idea came from, what it got right, and why it was taken too far. Along the way, he explores language, visual-spatial processing, the 200 million neurons connecting the hemispheres, and why real creativity may depend less on one side of the brain than on the coordination between both.

Intro clip: Creativity requires both hemispheres 00:00 Richard Davidson:One of the things that’s true about language, and especially about speech, is that it’s sequential. We can’t say six words at the same time. Just can’t do it. Cortland Dahl:I’m pretty sure my son could when he was really young, but in any case, it’s usually true. Richard Davidson:Usually true. But if you have pictures of those six words — let’s say there are six animals and you present a picture — you can see all six at the same time. That difference is what we call sequential versus parallel processing. There are certain kinds of visual-spatial skills that can be done more in parallel, and other kinds of skills and tasks that require more sequential activity. And of course, real human creativity, I think, requires both. This is why we have this massive fiber bundle that connects the two hemispheres together so they can work in an integrated way. I think it’s really an oversimplification to think that the right hemisphere is creative and the left is not. Every human being has the potential to be creative. When humans are the most creative, we’re harnessing the full capabilities of our brain. It’s not just the right hemisphere or the left hemisphere. It’s both. Welcome to Dharma Lab 00:01:30 Cortland Dahl:Hello everyone. Welcome back to another episode of Dharma Lab. I’m Cortland Dahl. I’m here with Dr. Richard Davidson, who we all affectionately call Richie, one of the great living neuroscientists on the planet. Today we’re going to continue a discussion we’ve had previously about some of Richie’s most important early work. Richie, I’m excited to ask you about this, partly because I myself have always wanted to geek out and hear more about these things. We always have a million things to talk about, but I never get to talk to you about this. In a previous episode, we talked about your very early research when you were just at Harvard, coming out of grad school, and your early work that showed differences between the different hemispheres of the brain — what is most simply referred to as asymmetry between these different hemispheres. We talked a lot about that, and we can put a link to that previous discussion. Left brain/right brain ideas in popular culture 00:02:47 This was back in the late seventies and into the eighties. Then something very interesting happened in the nineties. I graduated from high school in 1992 and was just starting college. There was a book at that time, and there was all sorts of stuff in the popular media about asymmetry, although that word probably wasn’t used. I remember a lot of things about the left side and right side of the brain. There was a book that I think was something like Drawing on the Right Side of the Brain. It was pointing, in many ways, to your work, which you were very much at the forefront of and had been for many years at that point. But I imagine, like many things, there was probably a lot of oversimplification and perhaps even misunderstanding about what the science really says and what’s really going on in the brain. So maybe we could start there, going back to this discussion about asymmetry and what your research and other researchers were really finding about the different hemispheres of the brain — and how that relates to things like creativity, being more logical, and all the stuff that was at work in our popular conversations about the brain at that time. Where did these ideas come from? 00:04:00 Richard Davidson:Thank you for that great introduction. There’s so much to say. Just being primed with that brings back intense memories from that period. I was very much living this. I published more than 100 papers on brain asymmetry in one way or another, and edited two books on brain asymmetry that were published by MIT Press. They were major compendiums at the time, with a scientist in Norway named Kenneth Hugdahl, one of my early collaborators. So yes, there’s so much to say. Let’s begin by asking where these ideas may have come from. In the previous episode of Dharma Lab, where we began to introduce this topic, one of the things we talked about is that the left hemisphere can speak and has language much more so than the right hemisphere — at least in most people. Language, handedness, and hemisphere differences 00:05:11 I should say that these broad generalizations about the left and right hemisphere are roughly true for right-handed people only. They are not necessarily true for people who write with their left hand. That itself is a whole topic of really interesting conversation, and we’ll bracket it. We can come back to it today briefly. But for now — and I apologize to all you lefties out there — since the majority of people are right-handed, roughly 85%, we’ll just stick with that for now. One of the questions scientists posed is this: if the left hemisphere can speak and really is the primary province of language, what is the right hemisphere doing? It’s presumably not just an appendage. It’s not just there to structurally latch on to the left hemisphere and hold it in place. It has to be doing something. Does it have some specialized role? If the left hemisphere is specialized more for language, is there some set of functions for which the right hemisphere may be better than the left hemisphere? Scientists discovered that there are certain kinds of visual and spatial tasks that the right hemisphere seems to be better at. Now, when we say “better,” what we mean is typically a little bit better. It’s not like there are absolute differences. It’s not like the right hemisphere can do this and the left hemisphere can’t do this. Similarly for language, although for language, the lateralization seems to be more definitive, particularly for speaking. For right-handed people, it’s pretty much the case that the left hemisphere can speak and the right hemisphere cannot speak. That’s pretty clear, and there are various ways in which that has been demonstrated. The myth of the creative right brain 00:07:36 Let me get back to the title of this popular book, Drawing on the Right Side of the Brain. There was a lot of hype that the right hemisphere is the creative hemisphere and the left hemisphere is the analytic hemisphere. When it got overgeneralized, it became something like: the right hemisphere is more interesting and the left hemisphere is boring. Those kinds of generalizations, in my view, were taken way too far. The other really important thing to keep in mind is that within a hemisphere, there is a lot of specialization as well. The anterior portions of the cerebral cortex, the prefrontal region, are doing something quite different from the back of the brain. The visual areas and the parietal area are doing different things. The parietal area is where visual information, auditory information, and kinesthetic information are all integrated. It’s kind of a multi-sensory melting pot. So these characterizations may apply to certain specific regions within a hemisphere, and not necessarily to the whole hemisphere. The 200 million neurons connecting both hemispheres 00:08:50 The other thin

    DL Ep.32: Dopamine Isn’t Your Problem with Dr. Richard Davidson and Dr. Cortland Dahl

    In this episode, Richie Davidson and Cortland Dahl unpack a very misunderstood molecule in popular culture: dopamine. Often blamed for craving, scrolling, distraction, and the endless loop of wanting more, dopamine is not something we can “detox” from or simply turn off. It is essential to motivation, aspiration, learning, and even the desire to practice meditation. Together, Richie and Cort explore what dopamine actually does in the brain, why wanting and liking are not the same thing, how novelty keeps us hooked, and how savoring may help us step out of compulsive loops and reorient toward what is genuinely nourishing.

Dopamine is essential in motivation, desire, seeking, and anything that is goal-directed. It has been described by the neuroscientist Kent Berridge as central to “wanting,” which he contrasts with something that it is often confused with: “liking.” Many times, we like the things we want. But not all the time. Sometimes we get caught up in a wanting cycle that is not necessarily leading to liking. But dopamine also plays an incredibly positive and important role. When I spring out of bed in the morning, go down to have my cup of tea, and have the strong aspiration to meditate, that is inevitably relying on the dopamine system too. Welcome to Dharma Lab (00:01:45) Cortland Dahl:Welcome everyone to another episode of Dharma Lab. I’m Cortland Dahl, and I’m here with my dear friend Richie, Dr. Richard Davidson, who, as I’m sure most of you know, is one of the most eminent neuroscientists on the planet. We’re incredibly fortunate to have him in discussion yet again, and for a topic that he is especially well suited to talk about, which is dopamine. I never thought dopamine would be a hook for a conversation like this, but it has taken on almost mythic status in popular culture. It has almost become the bad boy of the brain, like the amygdala, which is one brain region that always gets a bad rap and is associated with all sorts of negative things. These days, of course, we hear a lot about dopamine. You might have heard of things like a dopamine detox, which makes it sound like dopamine is some toxic thing in the brain that we want to get rid of or shut off or have less of in some way. So we thought we could get into the science of neurotransmitters generally, and then specifically dopamine. What does the science really say? What function does dopamine actually play, not only in our brains but in our ability to thrive and flourish? Richie, maybe we can start by zooming way out. I’m guessing people have heard the word dopamine. Some may have geeked out a little and learned more or even tried something like a dopamine detox. Other people may have heard about serotonin or other neurotransmitters, but my guess is that people’s understanding is still a little fuzzy. Could we start with the idea of a neurotransmitter, and then zoom in and look at dopamine specifically? What Is a Neurotransmitter? (00:03:46) Richard Davidson:Yes. Thank you so much. This is a juicy topic and very appropriate for Dharma Lab. There is a constellation of molecules in the brain that play many different roles. One of those roles is what you mentioned: a neurotransmitter. A neurotransmitter has a very specific role in mediating the interaction between two neurons. When one neuron fires, it sends an electric potential down the axon of that neuron. You can think of the axon as the wire extending from the cell body. The cell body is where the basic machinery is, and the axon extends from the neuron. Those axons can be short, and they can also be very, very long. If I asked you right now to move the big toe in your right foot, all of you should be able to do that. That is actually a neuron that extends all the way from your brain to your big toe. Cortland Dahl:That’s a single neuron? That’s cool. I didn’t know that. Richard Davidson:Yes, it is a single neuron. Neurons have many different lengths. At the end of the axon, there is machinery that releases a little packet of chemical. That packet binds to what is called a receptor on another neuron, and that initiates an electric change in the second neuron. That is how communication works between two or more neurons. That is called a neurotransmitter. Dopamine as Neurotransmitter and Neuromodulator (00:06:04) There are also neurotransmitters and other molecules that act as neuromodulators. A neuromodulator is different from a neurotransmitter. Dopamine, which is the topic of our conversation today, can serve as both a neurotransmitter and a neuromodulator. What is the difference? A neuromodulator alters the threshold for the firing of a neuron. It is not directly involved in cell-to-cell communication in the same way. It is more like the molecular soup in which the neuron resides, and that changes the threshold for the firing of the subsequent neuron. There are many molecules that serve as both neurotransmitters and neuromodulators, and dopamine is one of them. I think most neuroscientists would agree that we have not yet discovered the full range of neuromodulators and neurotransmitters in the human brain. It is a vast number. In the popular press, we’ve heard about dopamine, serotonin, maybe norepinephrine, maybe GABA. But there are hundreds of these molecules playing complicated roles. This is why, in general, it is extremely hazardous to pin a particular mental state on a single molecule. That is almost assuredly excessively simplistic and wrong. To the best of our knowledge, there is no well-defined psychological state that can be pinned to one specific molecule. It is much more complex than that. Why the Brain Is Too Complex for Simple Chemical Stories (00:08:20) Cortland Dahl:Just as a footnote, I think it’s mind-boggling when you hear how complex our brains are. Could you say a little about the estimates of how many neurons there are, and then beyond that, the connections between neurons? Now we’re talking about neurons communicating with each other. It’s an order of magnitude we can’t even comprehend. Richard Davidson:The estimated number of neurons in the human brain is about 85 or 88 billion. Cortland Dahl:That’s a “b,” everyone. Richard Davidson:Yes, billion. And the estimated number of connections among those neurons is in the trillions. Cortland Dahl:That’s in your head, everyone. Trillions of interconnections, and all these little communications, neuromodulators and neurotransmitters. The number of times that is happening right now, as you’re listening, is beyond what we can actually think about. Richard Davidson:That’s very true. I often reflect on this as a humility induction, because it is so complicated and we really understand so little of it at this point in time. If we pause to appreciate the complexity, and if we are honest with ourselves, it really is a humility induction. It also exposes how gross our measures are. We’ve done a lot of research with EEG, including the first paper we published with long-term meditation practitioners. EEG involves putting electrodes on the scalp surface. We use it because it is non-invasive and has very fast time resolution. But some people have likened EEG to taking a stethoscope, putting it on the hood of a car, and trying to understand how the car works by listening to the sounds from the stethoscope. That is what EEG is like. Cortland Dahl:So by “gross,” you mean it is such a coarse level of analysis for something that is so incredibly nuanced, beyond what our minds can comprehend. At some point in history, we’ll look back and it will seem like the Stone Age, the way we look at the brain now. Richard Davidson:Totally. There is a whole class of research that goes on in animals, and there are serious ethical issues about this kind of research. That could be the subject of another Dharma Lab. We won’t talk about that right now. Putting those ethical issues temporarily aside, those studies in animals are done because they use methods that cannot be used in humans. They are invasive methods that allow scientists to look at a much more granular level of a

The Brain Is a Storyteller (00:00:00) Cortland Dahl:The example you gave earlier, with Broca’s area and the split-brain findings, points to something fascinating. Parts of the brain are not always talking to each other. One part of the brain clearly knows something, but the part that communicates doesn’t. And it doesn’t stay silent. It makes something up. That’s the funny thing. In the absence of information, we don’t just stay silent. When we don’t know something, we are not comfortable with not knowing. Some instinctual part of us fills in the blanks almost all the time. Richard Davidson:Exactly. The human mind and brain is a storyteller. This is how we make sense of our world. We create these narratives. Welcome to Dharma Lab (00:01:03) Cortland Dahl:Welcome everyone to another episode of Dharma Lab. I’m Cortland Dahl, and I’m here with Dr. Richard Davidson, who we all lovingly call Richie. As many of you know, Richie is one of the most pioneering and widely studied neuroscientists on the planet. It’s a gift to be in conversation with him. Today we’re going to have a conversation I’ve wanted to have for a long time. I moved to Madison, Wisconsin in 2012 to study with Richie, and over the years I’ve heard many conversations at the Center for Healthy Minds about neuroscience, meditation, and the mind. But one thing that has never really happened, even for those of us who work closely with Richie, is a kind of broad “download” from him about the amazing body of work he has contributed to over the decades. Many people know Richie as a pioneer of contemplative science and contemplative neuroscience, the scientific study of how practices like meditation affect the mind, the brain, and our biology. But he is also a pioneer of affective neuroscience, which you might think of as the neuroscience of emotion. To be a pioneer in one field is extraordinary. To be a pioneer in two is kind of mind-boggling. So today I want to dig into some of those key insights, especially around neural asymmetry, which was a huge part of Richie’s early career and a central theme in affective neuroscience. Norman Geschwind and Behavioral Neurology (00:04:05) Richard Davidson:This topic is near and dear to my heart. It still is something I’m extremely interested in. It really began when I was a graduate student and had the opportunity to study with Norman Geschwind at Harvard Medical School. Geschwind was one of the great towering figures in what we now call behavioral neurology. I took a course with him on functional neuroanatomy, which is basically how different parts of the brain are connected to different behavioral functions. He was a neurologist, so he looked at people’s behavior as an external reflection of what was going on in the brain. He was an extremely keen observer of behavior, and he was also very demanding. He was what we would now call a localizationist, someone who believed in the specific localization of different functions in different parts of the brain. He used to say that if you don’t believe in localization, it’s because you don’t know neuroanatomy well enough. That pushed me to learn neuroanatomy deeply, including doing a human brain dissection. I also went on rounds with him, where he would visit neurological patients in the hospital. He would do these bedside exams that were incredible, using clever ways of interacting with patients to reveal what might be different about their brains. The Thumbtack Story: Emotional Memory Without Conscious Memory (00:06:31) Richard Davidson:One of the most famous demonstrations I saw involved a technique associated with Korsakoff, who described a syndrome of dementia related to alcoholism. Korsakoff showed that there can be a separation between memory for declarative information and memory for emotional information. A person with severe dementia might not recognize you if you came back the day after seeing them. They may have no conscious memory of who you are. But the question was whether the same was true for emotional information. The demonstration was this: a doctor would put a thumbtack in his hand and shake the patient’s hand. The patient would feel the prick and withdraw. The next day, the doctor would return and ask, “Do you know who I am?” The patient would say no. The doctor would identify himself and offer his hand again. But the patient refused to shake his hand. When asked why, the patient confabulated. He said something like, “I think your hand is dirty, and I don’t want to shake your hand.” That’s a beautiful demonstration of the dissociation between declarative memory and emotional memory. The declarative memory was gone. The patient did not recognize the doctor’s face or name and had no conscious memory of having seen him. But the emotional memory remained. Cortland Dahl:That one point has huge implications for life. We often have an interpretation of something and we are completely convinced of it. It seems so real that it doesn’t occur to us that it’s an interpretation. And yet the mind may have limited information, or may not be conscious of something, and it creates a whole story. In some cases, the story is flat-out wrong. But in the moment, it feels like reality. Richard Davidson:Exactly. And this is not just occurring in patients with frank brain damage. This is happening in all of us all the time. This is how our minds work. The mind creates a story about the world, and it’s from that story that we operate. It is not from some veridical perception of things in the world. There is no such thing as that. Our minds are constantly creating these stories. This relates directly to our insight pillar of well-being, which is about the narratives we are constantly creating about ourselves. Language, the Left Hemisphere, and the Corpus Callosum (00:12:12) Richard Davidson:One of Geschwind’s great contributions was his work on language-related lateralization in the human brain. In virtually all right-handed people, which is about 85 to 90 percent of the population, it is the left hemisphere that can speak, while the right hemisphere cannot. There is a key region called Broca’s area, named after Paul Broca. Damage to this area, often through stroke, can impair a person’s ability to speak. What is interesting is that this is one of the most clearly lateralized functions in the human brain. If this area in the left hemisphere is damaged, the corresponding area in the right hemisphere does not simply take over. The two hemispheres of the brain are very similar in many ways, but they have important differences. They are connected by the corpus callosum, a massive bundle of white matter that connects neurons in one hemisphere to corresponding neurons in the other. It is the largest pathway of connection in the human brain. In the past, for some patients with severe epilepsy, surgeons would cut the corpus callosum to prevent seizures from spreading from one hemisphere to the other. This left people with two disconnected hemispheres. When that happens, you can demonstrate strange dissociations. For example, if a split-brain patient is blindfolded and holds a glass in the left hand, the sensory information goes to the right hemisphere. But because the right hemisphere cannot speak, and the information cannot cross to the left hemisphere, the person may not be able to verbally identify the object. If you give them multiple-choice pictures, though, they can point to the glass. Cortland Dahl:That’s the same basic finding. One part of the brain clearly knows something, but the part that communicates doesn’t. And it doesn’t stay silent. It makes something up. Brain Asymmetry and Emotion (00:19:04) Richard Davidson:Most early research on brain asymmetry focused on the back of the brain, where language and some perceptual differences were located. The left hemisphere was specialized for speech and language. The right hemisphere seemed better at certain visual-spatial skills. But another early observation was especially interesting: when patients had damage to the left hemisphere, especially including the left prefrontal region, they were more likely to show depression after the brain damage. Two people could have comparable amounts of damage, but if the damage was in different hemispheres, the emotional consequences could be different. That led to the conjecture that the left hemisphere might play some role in emotions that are antithetical to depression. These patients often seemed anhedonic, meaning they were not experiencing much pleasure. There were also clinical reports of patients with right-hemisphere damage, whose left hemisp

    DL Ep.30: The Dharma of Relationships with Devon + Nico Hase

    Relationships can be one of the most powerful parts of the spiritual path because they reveal the parts of ourselves we cannot easily see alone. In this episode of Dharma Lab, Cortland Dahl and Richie Davidson are joined by meditation teachers and authors Devin and Nico Hase to explore how Buddhist practice can help us navigate love, conflict, vulnerability, appreciation, and repair. Drawing on their new book, This Messy, Gorgeous Love, they reflect on why relationships are inherently challenging, how they become mirrors for growth, and how simple practices like awareness, check-ins, and appreciation can turn partnership into a path of awakening.
