How does the brain represent the value of knowledge? In our paper--out now at Nature Neuroscience--we identify a representation of intrinsic information value within neural population structures in the orbitofrontal cortex in mice. www.nature.com/articles/s41593-026-02377-y #neuroskyence 🧠🧪 (1/8)

Representations of the intrinsic value of information in mouse orbitofrontal cortex - Nature Neuroscience

Mice are motivated to seek information of no extrinsic value. Recording neural activity in orbitofrontal cortex reveals a representation of the value of information that is distinct from the value of ...

Not a scientific post... Sharing for my dear friend, Constanze

Thats a tough post. It will almost be three years that I am not doing Active research and the reason is that I was diagnosed with metastatic Breast cancer. Many people imagine cancer as something with a beginning, a treatment, and eventually an end. Metastatic cancer is different.

The BARCCSYN (barccsyn.org) organized a great satellite meeting yesterday on multi-scale dynamics in decision-making. Many thanks to Hernando, Jaime, and Albert for putting together such an engaging event. Now, if you're at #FENS2026, don't miss our poster on Tuesday, presented by Carole Marchese!

Neuropixels + Optogenetics = Neuropixels Opto Combining high-resolution electrophysiology and optogenetics. 960 sites, 28 emitters, 2 colors. Today in @natmethods.nature.com doi.org/10.1038/s415... Thanks to @wellcometrust.bsky.social, @alleninstitute.org, @hhmijanelia.bsky.social & team.

Thanks to the Rhine-Main Neuroscience Network (www.rmn2.de) for inviting me to give a keynote in Oberwesel last week. Excellent science and great discussions across the network. The setting made it even more special: the Rhine valley, the castle, and a beautiful place to discover!

And that’s a wrap, my favorite meeting of the year is already over. Grateful to the SCGB community for such a stimulating meeting (karaoke included) and to the @simonsfoundation.org for always welcoming us so warmly. #neuroscience

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. Details and application: schadoc.univ-amu.fr/en/projects/...

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.

Facial expressions may involve an “everything, everywhere, all at once” type of coding in the brain, a new study suggests. By @natmesanash.bsky.social #neuroskyence www.thetransmitter.org/emotion-proc...

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!
