Is motor adaptation a form of associative learning?
In a new paper, now published in @eLife, we show that we can create associations between movement errors and arbitrary cues!

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

How do animals stay precise when their whole brain heats up or cools down? Larval zebrafish hunt accurately across a 10°C range. What enables such stability? What mechanism might support it? #zebrafish #neuroscience #temperature @STishbyTamari @ELSCbrain doi.org/10.1101/2025.0…

New preprint with Sritej, @reziliusReza , and Roberta Klatzky now on @biorxivpreprint!
Motor adaptation—our ability to correct errors using feedback—is attenuated in a Bayes-optimal manner when goals are uncertain.

Happy to announce that my lab @ Yale Psychology (actcompthink.org) will be accepting PhD apps this year (for start in Fall '26)!
Come for fun experiments on human learning, memory, & skilled behavior, stay for the best 🍕 in the US.
Please reach out w/ any questions!

#eNeuro | Interference Underlies Attenuation upon Relearning in Sensorimotor Adaptation
vist.ly/3n8vchh
English

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.

Happy to share our latest study led by @TantanBrainMan and our team @UCSF out today in Nature BME! Movement Responsive AI programmed BCI-aDBS improves naturalistic motion and reduces excessive movements at rest in PD.

🚨 New preprint alert! Attention isn’t always helpful.
We found that dividing attention can boost implicit adaptation—if timed right. A twist on the idea that distraction always impairs performance.

How does the motor system enable dexterous finger movement, and how does it recover after a stroke? Many questions remain, but in this ANN model designed to "mimic" physiological insights from humans and NHPs, we identified novel predictions:

Our @TrendsNeuro review on task representational spaces in OFC/vmPFC and in deep RL models is now out! Had a great time working on it with @nir_moneta and @nico_schuck, check it out here: cell.com/trends/neurosc…

I am happy to share my new preprint with David Whitney and Yifan Fang. We reveal two novel sequential effects in reaching movements and show that motor planning adheres to the principles of efficient coding.
