The cerebellum isn’t just about coordinating movement. It’s implicated in nearly every domain of cognition—from language to social behavior. But how exactly does the cerebellum contribute to action and cognition? 🧵 Check out our new paper w/ Rich Ivry.

Cerebellar Contributions to Action and Cognition: Prediction, Timescale, and Continuity
The cerebellum is implicated in nearly every domain of human cognition, yet our understanding of how this subcortical structure contributes to cognition remains elusive. Efforts on this front have ten...

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

New paper out! Ever wondered what it's like to be the Knight piece in chess? 🧠♞ In this study with

, we asked people to learn a visuomotor "Knight mapping" and make sequential decisions—linking motor learning with abstract planning. Find out more here:

Learning to Move and Plan like the Knight: Sequential Decision Making with a Novel Motor Mapping - Computational Brain & Behavior
Many skills that humans acquire throughout their lives, such as playing video games or sports, require substantial motor learning and multi-step planning. While both processes are typically studied se...
