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...

Thrilled that our new review "Motor Working Memory" is now in press at TiCS!

We argue that a dedicated research program on 'working memory for movements' is long overdue

📢 New preprint!
How do humans learn from arbitrary, abstract goals? We show that, when goal spaces can be compressed, costly working-memory processes give way to internalized reward functions, enabling efficient goal-dependent reinforcement learning. @annecollins.bsky.social arxiv.org/abs/2509.06810
Reward function compression facilitates goal-dependent reinforcement learning
Reinforcement learning agents learn from rewards, but humans can uniquely assign value to novel, abstract outcomes in a goal-dependent manner. However, this flexibility is cognitively costly, making l...

Fresh results now in bioRxiv! 🎉 We know about the function of NREM sleep for overnight memory consolidation. But what about REM sleep? We found that in aging, slow delta waves can intrude phasic REM periods, and this, is associated with worse overnight consolidation 🧠 (1/5) doi.org/10.1101/2025...
REM Sleep Misfires: Intruding Delta Waves Forecast Tau, Amyloid, and Forgetting in Aging
Rapid Eye Movement (REM) sleep degrades with age, and more severely in Alzheimer's disease (AD). REM sleep comprises about twenty percent of adult sleep, alternates between phasic and tonic periods, a...

What happens to motor adaptation—the way we correct errors with feedback—when feedback is indirect, like a number on a screen?

In our new paper in @royalsociety.org‬, we found that indirect feedback hinders learning compared to sensory feedback.

New preprint with Sritej, rezashadmehr.bsky.social, and Roberta Klatzky now on biorxivpreprint.bsky.social!

Motor adaptation—our ability to correct errors using feedback—is attenuated in a Bayes-optimal manner when goals are uncertain.

Welcome any and all feedback!
