Big thanks to @jrochav.bsky.socia, @annduan.bsky.social, @elofino.bsky.social @jeromeepsztein.bsky.social, Simon Musall and Srdjan Ostojic for their participation, as well as @lorifonto.bsky.social, @guilhemibos.bsky.social, Pascale Quilichini and Davide Reato for their help with the workshop

What a pleasure to spend two days in Marseille with such an outstanding group of scientists for my HDR and workshop. The discussions around distributed computations were exciting from start to finish. Thank you all for coming and helping make these two days so special.

📢 PhD opportunity between France and Italy

I’m recruiting an international PhD student for OPTIFLEX, a project co-supervised between Marseille and Genova on the optical control of neural circuits for action selection in mice.

22 years of Brain Science: what CoSyNe tells us about the evolution of Neuroscience Tracking the intellectual DNA of Computational and Systems Neuroscience through its flagship meeting

I tracked every keyword in 22 years of Cosyne abstracts to map how computational neuroscience evolved — from Bayesian brains to neural manifolds to LLMs — and where it's heading next.

New paper hot off the (pre-)press! We dig into the evolutionary origins of neural computations for behavioral control across mice, monkeys, and humans: www.biorxiv.org/content/10.6....

As our lab's first foray into comparative analysis of neural dynamics, I’m super excited about this work! 1/18

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

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

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!

Putting the 'Spotlight' on a recent article by @fannycazettes.bsky.social et al. by discussing how “brain leakage” can expose cognitive computations in bodily movements – in turn opening new ways to track cognition. Now out in @cp-trendscognsci.bsky.social. authors.elsevier.com/a/1mDCZ4sIRv...

I remember when we used to think that all neurons were specialized.

When @natrevneuro.nature.com asked me to highlight a paper that influenced both my field and my own research, I immediately thought of the work on mixed selectivity by @matrig.net, @stefanofusi.bsky.social, and colleagues.

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!

Reproducibility is a team sport Building reproducible systems across labs is possible, even in large-scale neuroscience—with rigor and collaboration.

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.
