We derived six laws of psychophysics from a single efficient-coding equation. The laws include Weber's law; scaling laws in visual working memory (which had been noted before, but with unclear theoretical justification); Wei & Stocker's law of human perception; arthurprat.com/pdfs/Prat-Ca...

Are brains and artificial neural networks converging onto universal representations? There is a seductive idea making the rounds in NeuroAI / machine learning: train systems well enough, and they all converge on the same representation of reality (i.e. a unique world model). We have thoughts™ 1/n

Now out at PNAS! The final version includes a smart analysis suggested by a reviewer showing that biomarkers collected in blood track our neural population metrics. A very exciting connection between basic neurophys and translational approaches. Congrats to all! www.pnas.org/doi/10.1073/...

So excited to see you all tomorrow at #CogSci2026! I will be presenting at 11:07 in the Ipanema room. Thanks to the @cogscisociety.bsky.social team for organizing this wonderful conference and for supporting us with the Diversity Award. Without it, I wouldn’t have been able to be here in person.

This is fantastic work. Drew et al, show how visual processing and memory are tightly linked. This link has consequences for we can think about memory impairments through the lens of (active) vision. Please do check it out.

Our new paper is out this week in Nature Neuroscience! www.nature.com/articles/s41... We built a BCI that works with the brain's natural geometry — and we found that people could learn to play a video game with their brains in <1 hr of training. This efficiency is groundbreaking & here's why:

I totally agree, science is not a simple optimization problem, or at least not in the form conceived by most existing systems. @battleday.bsky.social and I wrote about this recently from a somewhat different perspective (emphasizing the 'problem problem'): gershmanlab.com/pubs/Battled...
