The secrets of resilient aging | Beth Mormino & Anthony Wagner

This week on the show, we're have our sights set on healthy aging. What would it mean to be able to live to 80, 90 or 100 with our cognitive abilities intact and able to maintain an independent lifestyle right to the end of our days?  We're joined by Beth Mormino [/node/3382] and Anthony Wagner [/node/3537] who lead the Stanford Aging and Memory Study [https://memorylab.stanford.edu/get-involved/stanford-aging-memory-study-sams], which recruits cognitively healthy older adults to understand what makes their brains particularly resilient — and how more of us could join them in living the dream of healthy aging.

episode Building AI simulations of the human brain | Dan Yamins artwork
Building AI simulations of the human brain | Dan Yamins

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

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.

What the other half of the brain does | Brad Zuchero

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

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 [https://neuroscience.stanford.edu/people/kim-butts-pauly] and Raag Airan [https://neuroscience.stanford.edu/people/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.  Mentioned on the Show * Meet the 2025 Neurosciences Postdoctoral Scholars [https://neuroscience.stanford.edu/news/meet-2025-neurosciences-postdoctoral-scholars] (Wu Tsai Neuro, 2025) * Butts Pauly Lab [https://kbplab.stanford.edu/] * Airan Lab [http://airan-lab.stanford.edu/] * Non-invasive brain stimulation opens new ways to study and treat the brain [https://neuroscience.stanford.edu/news/non-invasive-brain-stimulation-opens-new-ways-study-and-treat-brain] (Wu Tsai Neuro, 2025) * Advancing Brain Resilience: 2024 Catalyst and Pilot Grant Awards [https://brainresilience.stanford.edu/news/advancing-brain-resilience-2024-catalyst-and-pilot-grant-awards] (Knight Initiative for Brain Resilience, 2024) * Researchers find response to ketamine depends on opioid pathways, but varies by sex [https://med.stanford.edu/news/all-news/2024/02/ketamine-sex-opioid.html] (Stanford Medicine) * A New Focused Ultrasound Neuromodulation System for Preclinical Brain Research [https://www.fusfoundation.org/posts/a-new-focused-ultrasound-neuromodulation-system-for-preclinical-brain-research/] (Focused Ultrasound Foundation, 2024) * Translating Neuroscience Advances into Real World Uses [https://neuroscience.stanford.edu/news/translating-neuroscience-advances-real-world-uses] (Wu Tsai Neuro, 2023) Get in touch We want to hear from your neurons!
