Imagine Thursday. Does Thursday have a color? What about the sound of rain — does that sound taste like chocolate? Or does the sound of a saxophone feel triangular to you?

For about 3% of the population, the sharp lines between our senses blend together. Textures may have tastes, sounds, shapes, numbers may have colors. This sensory crosstalk is called synesthesia, and it's not a disorder, just a different way of experiencing the world.
To learn about the neuroscience behind this fascinating phenomenon and what it tells us about how our brains perceive the world, we were fortunate enough to speak with David Eagleman, a neuroscientist, author, and entrepreneur here at Stanford. Eagleman has long been fascinated by synesthesia and what it means about how our perceptions shape our reality.

We also discuss Eagleman's work with Neosensory, a company that develops technology to help individuals with hearing loss by translating sound into vibrations on the skin. The episode highlights the adaptability and plasticity of the brain, offering a deeper understanding of how our perceptions shape our reality.
In addition to his research, Eagleman is a prolific communicator of science — the author of several books including Livewired and Incognito and host of the PBS series "The Brain with David Eagleman" and the new podcast series "Inner Cosmos".

Building AI simulations of the human brain | Dan Yamins 32:56

2 days ago32:56

32:56

This week on the show: Are we ready to create digital models of the human brain? Last month, Stanford researcher Andreas Tolias and colleagues created a "digital twin" of the mouse visual cortex. The researchers used the same foundation model approach that powers ChatGPT, but instead of training the model on text, the team trained in on brain activity recorded while mice watched action movies. The result? A digital model that can predict how neurons would respond to entirely new visual inputs. This landmark study is a preview of the unprecedented research possibilities made possible by foundation models of the brain—models which replicate the fundamental algorithms of brain activity, but can be studied with complete control and replicated across hundreds of laboratories. But it raises a profound question: Are we ready to create digital models of the human brain? This week we talk with Wu Tsai Neuro Faculty Scholar Dan Yamins, who has been exploring just this question with a broad range of Stanford colleagues and collaborators. We talk about what such human brain simulations might look like, how they would work, and what they might teach us about the fundamental algorithms of perception and cognition.

What ChatGPT understands: Large language models and the neuroscience of meaning | Laura Gwilliams 42:31

16 days ago42:31

42:31

If you spend any time chatting with a modern AI chatbot, you've probably been amazed at just how human it sounds, how much it feels like you're talking to a real person. Much ink has been spilled explaining how these systems are not actually conversing, not actually understanding — they're statistical algorithms trained to predict the next likely word. But today on the show, let's flip our perspective on this. What if instead of thinking about how these algorithms are not like the human brain, we talked about how similar they are? What if we could use these large language models to help us understand how our own brains process language to extract meaning? There's no one better positioned to take us through this than returning guest Laura Gwilliams, a faculty scholar at the Wu Tsai Neurosciences Institute and Stanford Data Science Institute, and a member of the department of psychology here at Stanford.

35:00

We've talked about glia and sleep. We've talked about glia and neuroinflammation. We've talked about glia in the brain fog that can accompany COVID or chemotherapy. We've talked about the brain's quiet majority of non–neuronal cells in so many different contexts that it felt like it was high time for us to take a step back and look at the bigger picture. After all, glia science was founded here at Stanford in the lab of the late, great Ben Barres. No one is better suited to take us through this history and lead us to the frontiers of the field than today's guest, Brad Zuchero. A former Barres lab postdoc, and now an emerging leader in this field in his own right, Brad gives us an overview of our growing understanding of the various different kinds of glia and their roles in brain function, and shares the exciting discoveries emerging from his lab — including growing evidence of a role for myelin in Alzheimers disease.

Stimulating the brain with sound | Kim Butts Pauly and Raag Airan 30:43

6 weeks ago30:43

As we gain a better understanding of how misfiring brain circuits lead to mental health conditions, we'd like to be able to go in and nudge those circuits back into balance. But this is hard — literally — because the brain is encased in this thick bony skull. Plus, often the problem you want to target is buried deep in the middle of a maze of delicate brain tissue you need to preserve. Today we're going to be talking with neuroscientists who aim to solve this problem with sound. And not just any sound: ultrasound. Kim Butts Pauly and Raag Airan from the Stanford Department of Radiology are developing ultrasound technology in a couple of different ways to essentially reach into the brain to treat brain disorders that are otherwise hard to access. These uses of ultrasound haven't yet reached the clinic, but could be entering clinical testing in people in the next few years.

Does good sleep insulate the brain against Alzheimer's? | Erin Gibson 39:25

8 weeks ago39:25

39:25

We're kicking off our new season with a deep dive into one of neuroscience's most fascinating mysteries: sleep. This unconscious third of our lives isn't just about rest – it's absolutely critical for brain health, memory consolidation, and overall well-being. But here's where it gets intriguing: recent research suggests that increased napping as we age might be an early warning sign of Alzheimer's disease. To unpack this complex relationship, we're thrilled to welcome back Erin Gibson, assistant professor of psychiatry at Stanford School of Medicine and Wu Tsai Neuro affiliate. We'll explore whether age-related sleep changes are potential contributors to brain degeneration or valuable early indicators of otherwise invisible brain disorders, possibly opening doors for early intervention. We'll also learn about Gibson's research, supported by the Knight Initiative for Brain Resilience at Wu Tsai Neuro, which investigates how myelin—the insulation of our nerve cells—could be a key missing link in understanding the relationship between sleep and brain health. Join us for an enlightening discussion that might just change how you think about your nightly slumber and its profound impact on long-term cognitive function.

How to live in a world without free will | Robert Sapolsky 40:46

21 weeks ago40:46

40:46

Today, we are speaking with the one and only Robert Sapolsky, a Stanford neurobiologist, a MacArthur "Genius", and best-selling author of books exploring the nature of stress, social behavior, and — as he puts it — "the biology of the human predicament." In his latest book, Determined , Sapolsky assertively lays out his vision of a world without free will — a world where as much as we feel like we're making decisions, the reality is that our choices are completely determined by biological and environmental factors outside of our control. Before we get into it, it's worth saying that where this is heading, the reason to care about this question is that Sapolsky's argument has profound moral implications for our understanding of justice, personal responsibility, and whether any of us deserve to be judged or praised for our actions.

Join us as we dive back into the world of psychedelic medicine with anesthesiologists Boris Heifets and Theresa Lii, who share intriguing new data that sheds light on how ketamine and placebo effects may interact in treating depression. We explore provocative questions like: How much of ketamine's antidepressant effect comes from the drug itself versus the excitement of being in a psychedelics trial? What do we know about how placebo actually works in the brain? And should we view the placebo effect as a feature rather than a bug in psychiatric treatment? Join us as we examine the complex interplay between psychoactive drugs, the brain's own opioid system, and the healing power of hope in mental health care.

Earlier this year, President Obama's signature BRAIN Initiative, which has powered advances in neuroscience for the past 10 years, had its budget slashed by 40%. Over the past decade, the BRAIN Initiative made roughly $4 billion in targeted investments in more than 1500 research projects across the country and has dramatically accelerated progress tackling fundamental challenges in neuroscience. As we head into the next federal budget cycle, the future of the initiative remains uncertain. Today we take stock of how the BRAIN Initiative transformed neuroscience over the past 10 years, and what the outlook is for the future of the field. To give us an unparalleled behind the scenes view, we are fortunate to have Bill Newsome with us on the show. A world renowned expert in the brain mechanisms of visual perception and decision-making, Bill co-chaired the original BRAIN Initiative planning committee in 2013 (the same year he became the founding director of the Wu Tsai Neurosciences Institute here at Stanford).

The cannabinoids within: how marijuana hijacks an ancient signaling system in the brain | Ivan Soltesz 37:33

29 weeks ago37:33

37:33

Given the widespread legalization of cannabis for medical and recreational uses, you'd think we'd have a better understanding of how it works. But ask a neuroscientist exactly how cannabinoid compounds like THC and CBD alter our perceptions or lead to potential medical benefits, and you'll soon learn just how little we know. We know that these molecules hijack an ancient signaling system in the brain called the "endocannabinoid" system (translation: the "cannabinoids within"). These somewhat exotic signaling molecules (made of fatty lipids and traveling "backwards" compared to other transmitters) have been deeply mysterious until recently, when new tools made it possible to visualize their activity directly in the brain. So what is the "day job" of the endocannabinoid system — and how does it connect to the dramatic highs that come with taking THC or the medical benefits of CBD? To unpack all this, we're talking this week with neuroscientist Ivan Soltesz, the James Doty Professor of Neurosurgery and Neuroscience at Stanford, and a leading expert on the endocannabinoid system.

Memory Palaces: the science of mental time travel and the brain's GPS system | Lisa Giocomo (Re-release) 25:50

31 weeks ago25:50

25:50

Today we are re-releasing an episode we did last year with Stanford neurobiologist Lisa Giocomo exploring the intersection of memory, navigation and the boundaries we create between ourselves and the world around us. This episode was inspired by the idea of memory palaces. The idea is simple: Take a place you're very familiar with, say the house you grew up in, and place information you want to remember in different locations within that space. When it's time to remember those things, you can mentally walk through that space and retrieve those items. This ancient technique reveals something very fundamental about how our brains work. It turns out that the same parts of the brain are responsible both for memory and for navigating through the world. Scientists are learning more and more about these systems and the connections between them, and it's revealing surprising insights about how we build the narrative of our lives, how we turn our environments into an internal model of who we are, and where we fit into the world. Join us to learn more about the neuroscience of space and memory. Before we get into this week’s episode, we have a favor to ask. We're working to make this show even better, and we want to hear from you. We're in the process of gathering listener input and feedback.

Why new Alzheimer's drugs don't work | Mike Greicius, Stanford University School of Medicine 25:48

In the past few years, Big Pharma has released not one, but three new treatments for Alzheimer’s disease. Aducanemab (2021), Lecanemab (2023), and Donanemab (2024), are the first treatments to effectively clear the brain of amyloid plaques — the sticky protein clumps whose build-up in the brain has defined the disease for decades. The problem? They may not help patients at all. Today’s guest, Stanford neurologist Mike Greicius , considers the new amyloid-clearing drugs a major disappointment — and worse, says they likely do more harm than good for patients. Despite this critique, Greicius, thinks that the next few years will be an exciting time for novel Alzheimer’s therapies, as growing biological understanding of Alzheimer’s risk and resilience bear fruit with promising new approaches to treatment. Learn More: Greicius is the Iqbal Farrukh and Asad Jamal Professor of Neurology and Neurological Sciences at Stanford Medicine, and a member of the Knight Initiative for Brain Resilience and Alzheimer's Disease Research Center at Stanford University.

Depression's distinctive fingerprints in the brain | Leanne Williams, Stanford University 28:11

Getting help for depression can be like purgatory. Setting aside for a moment the stigma and other barriers to seeking treatment in the first place, finding the right combination of medication and/or therapy can be a months- or years-long process of trial and error. And for about one third of people, nothing seems to work. Today we're talking with Dr. Leanne Williams , the founding director of the Stanford Center for Precision Mental Health and Wellness and Vincent V.C. Woo Professor in the Stanford Department of Psychiatry and Behavioral Sciences. Williams and her team have recently used brain imaging and machine learning techniques to identify six distinct "biotypes" of depression — each of which may require a different approach to treatment. Beyond setting the stage for more targeted therapies, better understanding the biology behind the disease could finally cut through the stigma of one of the world's most common brain disorders.

How the brain helps cancers grow | Michelle Monje 21:27

Today, we're talking with Stanford neuro-oncologist, Michelle Monje . This is actually the third time we've had Michelle on the show, in part because she's been a pioneer of three exciting frontiers in neuroscience — so far! This week, we're going to talk about cancer neuroscience. Michelle founded this new field with her discovery that deadly brain tumors not only link up physically with the healthy brain tissue surrounding them, but the cancers actually need the brain's electrical activity to grow and spread. It turns out that many cancers — not only in the brain — depend on nervous system innervation for their survival. Understanding this dependent relationship better may present an exciting new line of attack for oncology. Join us to learn more! News coverage Brain tumors caused by normal neuron activity in mice predisposed to such tumors Brain tumors form synapses with healthy neurons, Stanford-led study finds Deadly brain cancers act like 'vampires' by hijacking normal cells to grow Engineered immune cells target broad range of pediatric solid tumors in mice Relevant Publications Glioma synapses recruit mechanisms of adaptive plasticity Glioblastoma remodelling of human neural circuits decreases survival Electrical and synaptic integration of glioma into neural circuits Targeting neuronal activity-regulated neuroligin-3 dependency in high-grade glioma Neuronal Activity Promotes Glioma Growth through Neuroligin-3 Secretion Review Articles The neuroscience of cancer Cancer hallmarks intersect with neuroscience in the tumor microenvironment Roadmap for the Emerging Field of Cancer Neuroscience Episode Credits This episode was produced by Michael Osborne, with production assistance by Morgan Honaker, and hosted by Nicholas Weiler.
