I’m very excited to share our new paper, led by the very talented Jack Bowler, a postdoc in the lab! www.nature.com/articles/s41... We all know that the way we learn something matters. But how does a training curriculum actually shape how the brain learns to solve a problem? a 🧵 1/N

Structured experience shapes strategy learning and neural dynamics in the medial entorhinal cortex - Nature Neuroscience

The authors use recurrent neural networks to predict how structured prior experience shapes neural dynamics as mice learn flexible timing strategies during complex context-dependent behavior.

I’m so happy to share that I’ll be starting as an Assistant Professor of Psychology at the University of Wisconsin-Madison in Fall 2027! I'm incredibly excited to head back to the Midwest, get to work with an incredible group of colleagues, and live in beautiful Madison, WI. 🦡🎊

After 3 years working with the great Wilma Bainbridge at UChicago, I’m thrilled to be heading home to Canada for a new chapter at the Rotman School of Management in Toronto! I’ll be bringing memorability into marketing, showing how brands can optimize their assets for cognition.

Why do some goals spread across people and generations, while others emerge only transiently? We argue that human goals are both drivers and products of cultural evolution: our individual pursuits are shaped by our cultural environments, and the goals we pursue in turn reshape those environments.

We broke Weber's law. By manipulating the prior (ie the frequencies of small and large magnitudes), we changed how people's accuracy depended on magnitude. When large magnitudes were more frequent, subjects became more precise about them. This points to efficient coding, dynamically implemented.

@arthurpr4t.bsky.social has a new preprint with important results on a famous psychophysical law (Weber's law). It isn't, in fact, a law, because it can be broken. A more fundamental principle (efficient coding) shows when and why Weber's law holds true. www.biorxiv.org/content/10.6...

New preprint! 🎉 How can we measure how the nervous system knows, moment to moment, where the body is as it moves? We introduce a continuous tracking paradigm to measure the hidden dynamics of proprioception—revealing it is faster and more precise than vision during movement. tinyurl.com/yf297k53

Tracking the hidden dynamics of proprioception

Every movement unfolds with a simple question: Where is my body? The nervous system answers through proprioception - the sense of limb position (static position sense) and movement (dynamic propriocep...

Excited for the opportunity to investigate how stroke affects peripheral nerve signaling and, in turn, sensorimotor function. With an amazing transdisciplinary team, we hope to uncover how to effectively engage the peripheral nervous system after stroke. Thank you NIH NICHD!
