Super thrilled to finally share the results of our team effort, from the lab of the one and only @ayab.bsky.social. Hopefully it will stir interesting discussions about how the brain balances continuity and segmentation

Excited to share a new paper spearheaded by the wonderful @baror-shira.bsky.social:

We test the link between serial dependence (as an index of continuity) and event boundaries (indexing segmentation). A few key findings in the thread:

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...

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? 🧵

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

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...

📢 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

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...

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...

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!

#eNeuro | Interference Underlies Attenuation upon Relearning in Sensorimotor Adaptation
vist.ly/3n8vchg

In Exp 5 we show that prolonged experience with baseline feedback produces attenuated adaptation. This is strikingly similar to latent inhibition, and consistent with our other evidence suggesting that motor adaptation is a form of associative learning.

Many thanks to the editor and reviewers for the wonderful feedback, and especially for recognizing that “the results of experiment 5 and the link to classical conditioning are what is most exciting in this paper”. We agree...

Interference Underlies Attenuation upon Relearning in Sensorimotor Adaptation Savings refers to the gain in performance upon relearning. In sensorimotor adaptation, savings is tested by having participants adapt to perturbed feedback and, following a washout block during which ...
