The powerful new generation of AI tools that has come out over the past few years — DALL-E, ChatGPT, Claude, Gemini, and the rest — have blown away our old ideas about what AI can do and raised questions about what it means for computers to start acting... intelligent?

This week, we ask what the rise of these systems might teach us about our own biological intelligence — and vice versa. What does modern neuroscience have to say about how AI could become as flexible, efficient, and resilient as the human brain.

Few people are better positioned to speak to the intersection of neuroscience and AI than today's guest: Surya Ganguli.

Ganguli's lab produced some of the first diffusion models — which are at the foundation of today's AI revolution — and is now working to understand how complex emergent properties arise from biological and artificial neural networks.

Ganguli is a member of the Neuroscience Theory Center at the Wu Tsai Neurosciences Institute, a Senior Fellow at Stanford's Institute for Human-Centered Artificial Intelligence (HAI), and an associate professor in Stanford's Department of Applied Physics.

At some point in our lives, we all struggle with memory — learning a new name, remembering that book you were reading just yesterday or that word on the tip of your tongue.

So what can neuroscience teach us about why we remember, why we forget, and how we might even improve our memories?

To answer this question, I spoke with neuroscientist Anthony Wagner, a memory expert in Stanford's Department of Psychology.

Today, we're going to talk about how psychedelics alter our perception of reality and what that says about... reality!

Welcome to part two of our conversation with Stanford anesthesiologist and psychedelics researcher Boris Heifets!

Last time, we talked with Boris about the question of why psychedelics help people with mental health disorders.

This week, we're going to dive into a different question, which is to explore how psychedelics work in the brain. How are they able to alter something as fundamental as our perceptions of reality — and could understanding these effects teach us about the nature of our everyday perceptions?
