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. Welcome any and all feedback! tinyurl.com/y9kjcfzj
Scientists @CellPressNews reviewed 408 YouTube clips of sleeping cats and found 2/3 curled up on their left side. Here’s the neuroscience behind why:🧵 (Please watch their video abstract I put on the last post - it’s 100% worth it)
Goal-directed movement is central to our everyday lives, & #stroke can impact how we move. In a new blog article, Dr. @cwinstein shares insights from her career, including the importance of learning from research participants & others w/ lived experience. asnr.com/files/Importan…
📜Out in Nat. Commun! We propose a novel framework called “predictive alignment”, which trains the chaotic RNN via a biologically plausible rule. Collaborated with @ClopathLab nature.com/articles/s4146…
🚀 New Open-Source Release! PyTorchTNN 🚀 A PyTorch package for building biologically-plausible temporal neural networks (TNNs)—unrolling neural network computation layer-by-layer through time, inspired by cortical processing. PyTorchTNN naturally integrates into the…
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!
Our newest preprint “A novel approach-avoidance task to study decision making under outcome uncertainty” investigates the dynamics of approach-avoid decisions! Check out biorxiv.org/cgi/content/sh…, led by @ziweicheng_zc and @NadjaGingJehli from @Franklab_LNCC.
Wow! These are profound aging declines. We need much more attention to tracking/slowing/reversing these declines in the longevity space
As we age, we move slower and less precisely—but how much, exactly? We analyzed one of the largest datasets on motor control to date. Findings: Reaction time: –1.2 ms/year Movement time: –2.3 ms/year Precision: –0.02°/year tinyurl.com/f9v66jut
📢 I'm looking for a postdoc to join my lab at NYU! Come work with me on a principled, theory-driven approach to studying language, learning, and reasoning, in humans and AI agents. Apply here: apply.interfolio.com/170656 And come chat with me at #CogSci2025 if interested!
