Super happy to see our new study, on how the interpeduncular nucleus (IPN) regulates nicotine reward, out today in @cp-neuron.bsky.social!

Using #chemogenetics, we @faurelab.bsky.social show that blocking IPN activation enhances VTA responses and increases nicotine's rewarding effect.

The interpeduncular nucleus blunts the rewarding effect of nicotine
Nicotine activates the dopamine reward system to promote consumption and addiction, but the brain has a natural brake to counteract it. Jehl, Ciscato, Vicq, Guyon, et al. identified the interpeduncula...

Happy to share our new protocol in @cp-starprotocols.bsky.social: CATCH—Covalent Anchoring of Tethered Ligands to Chemogenetic Handles!

This method enables precise, long-lasting, and pharmacologically specific inhibition of brain receptors in vivo.

Friday, November 13, 2015, Paris fell victim to the deadliest terrorist attacks ever carried out in France. Ten years later, to the day, Paris remembers and honors their memory.

On this week’s cover of The Lancet, a new letter: “Gaza’s healthocide: medical societies must not stay silent”.

Read the letter and more in our latest issue: tinyurl.com/5n85x448
Cover of The Lancet's Oct 4, 2025 issue. Cover quote reads: "Most medical and surgical societies worldwide have remained silent or issued vague statements about Gaza's healthocide [...] Staying silent while pretending to be neutral is, in effect, a form of complicity."

Thrilled to share that our work is now published in Science! ✨

We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭

Today, our article "The entities enabling scientific fraud at scale are large, resilient, and growing rapidly" is finally published in PNAS. I hope that it proves to be a wake-up-call for the whole scientific community.

We need your help!!! 🧠🧪💤

If you are human, you fall asleep at least once a day! What happens in your mind then?

Scientists know actually very little about this private moment.

We propose a 20-min survey to get as much data as possible!

The other shoe finally dropped. We were notified this morning that our NIH funding for our work on photopharmacology tools has been cut.

We’ll keep going with or without them 🤷‍♂️
