Did you know that facial expressions reveal more than meets the eye? 🤯

Our new study shows that even a mouse's face 🐭 can reflect hidden neural computations🧠. Turns out, facial expressions are more than just emotions!

We're so excited to see this paper out @natneuro.nature.com 🎉

Facial expressions in mice reveal latent cognitive variables and their neural correlates

Can you read a mouse’s mind just by looking at its face?

Our new study featured in The Transmitter by @lauren-schneider.com! 🎉 Big thanks to @zeronoiselab.bsky.social and @computingnature.bsky.social for their comments on the work.

The Transmitter @thetransmitter.bsky.social · 8d

Facial movements reflect a mouse’s decision-making patterns independent of their chosen action during a foraging task, per a new study.

Building reproducible systems across labs is possible, even in large-scale neuroscience. You just need rigor, collaboration and the willingness to look your own practices in the eye, writes Anne Churchland.

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions. doi.org/10.1038/s415...

So great to welcome long-term collaborator Luca Mazzucato (@neuroai-uoregon.bsky.social) to Marseille (France)! He just gave a fantastic talk about the neural mechanisms of optimal performance. 🧠

🚀 Big News: For those interested, his department at the University of Oregon will be hiring this fall!

Our work, out at Cell, shows that the brain’s dopamine signals teach each individual a unique learning trajectory. Collaborative experiment-theory effort, led by Sam Liebana in the lab. The first experiment my lab started just shy of 6y ago & v excited to see it out: www.cell.com/cell/fulltex...
