#sfn2025 interested in how eye movements 👀 versus orofacial movements influence 🐭 visual cortex activity 🧠? Check out poster R8 by @atika-syeda.bsky.social NOW!

I am recruiting graduate students for the experimental side of my lab @mcgill.ca for admission in Fall 2026!
Get in touch if you're interested in how brain circuits implement distributed computation, including dopamine-based distributed RL and probabilistic representations.

To study how animals understand the physical world (and the rules that govern its dynamics), @jinyao-y.bsky.social trains rats to play fetch with robots 🐀🤖🎾

To learn more, come to our poster Tuesday morning!
[Board W11] Rats learn and use intuitive physics knowledge to solve fetch tasks.

Cortical control of innate behavior from subcortical demonstration Motor control in mammals is traditionally viewed as a hierarchy of descending spinal-targeting pathways, with frontal cortex at the top. Many redundant muscle patterns can solve a given task, and this...

(1/11) Today I preprinted a lot of work from my postdoc with @dudman.bsky.social, which started with a question of how the nervous system balances flexibility with efficiency of learning. The thread below gives some background....
