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 may involve an “everything, everywhere, all at once” type of coding in the brain, a new study suggests.

Facial expressions less reflexive than previously thought
A countenance such as a grimace activates many of the same cortical pathways as voluntary facial movements.

New preprint from the lab!
A frontal motor circuit for economic decisions and actions:
www.biorxiv.org/content/10.6...
We use a novel task in mice, cortex-wide imaging and optogenetics, NPX recording and modelling to reveal a circuit mechanism that transforms abstract decisions to spatial actions.

Last night Adam Kampff, the glue, the light, the catalyst, the builder, the smile, left us. He and his work transformed the lives of many labs, scientists, students. He inspired and was generous to his last transformation, working tirelessly to set up a foundation to continue the work.Thank you!
