Associate Teaching Professor of Neuroscience at Johns Hopkins University. I also dabble in electronic music, drawing/painting, some stuff with moss and upcycled circuitboards.....
Some new 40HzOscillator stuff I’ve been working on. This went over pretty well at the Halloween gig.

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
Adult human brains have between 86-100 billion neurons and every single one is unique - like snowflakes! ❄️
🧠📈 In this 3D rendering by our #ElectronMicroscopy team, we see 3 different shapes. Can you name all of them?

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

Bite-sized pieces of sound and video—each one around a minute or less. Over time, these tidbits will be synthesized into a larger audiovisual montage. Gotta have goals!

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!
