How do you simulate a brain in any detail with a simple digital (or even quantum) computer? "Making a connection" in the brain is not just "information processing." It's physical. There is no workable "software" driving the mind. It is the "hardware" that is messy and unique, and constantly changing

Sad day for America that Anthony Fauci needed to receive a pardon to prevent persecution from those who should be thanking him. He dedicated his career to improving human health & saved millions of lives during COVID. He should be receiving a medal, not a pardon #❤️Fauci @doctorfauci.bsky.social

Did you know that Claude Shannon also developed maze solving algorithms? Which he implemented physically using a wooden mouse named Theseus. To solve a given maze, on a grid, Theseus used two modes: 🧵

I wrote an introduction to RL for neuroscience last year that was just published in NBDT: tinyurl.com/5f58zdy3 This review aims to provide some intuition for and derivations of RL methods commonly used in systems neuroscience, ranging from TD learning through the SR to deep and distributional RL!

Hung out with a student today who just wanted to talk about actor-critic models, diffusion models, the prisoner's dilemma and some other fun stuff. We doodled to get some ideas out of our heads. Not pretty but very fun!
