Compositional neural dynamics during reaching
The complex mechanics of the arm make the neural control of reaching inherently posture dependent. Because previous reaching studies confound reach direction with final posture, it remains unknown how...

Variance partitioning is used to quantify the overlap of two models. Over the years, I have found that this can be a very confusing and misleading concept. So we finally we decided to write a short blog to explain why.

New preprint from the lab! 🧠 Led by Juliana Trach, w/ Sophia Ou Using fMRI, we discovered evidence for time-sensitive reward prediction errors (RPEs) in the human cerebellum. Builds on, and extends, recent work in both rodents and NHPs

Exited to share tomorrow new updates on trying to figure out how the neocortex and cerebellum talk to each other. Work by
@carobellum.bsky.social
, Ali Shabazi, and others in the lab!

We're excited to share our new paper: “cTBS of prefrontal cortex in the behaving macaque: no evidence for within-target inhibition or cross-hemisphere disinhibition of neural activity”

What did we find? Mostly... what we didn’t! 🧵

Heading to
#cosyne2025
? We're presenting new data exploring the geometry of neural dynamics in M1, PMd, PFC, SMA, and GPi during reaching movements with varying start locations, directions, and extents. Find me at Poster Session 3-091 — or anytime before or after!

Can the motor system use sensory expectations to prepare for unexpected events? Excited to share my latest work with
@andpru.bsky.social
– where we establish that sensory expectations shape neural population dynamics in motor circuits! 🧵 and paper below 1/

It’s striking how profoundly the prevailing theoretical framework shapes our thinking.
