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.

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.

I decided not to attend, mainly for political reasons, and instead used the money to go to the Society of Neuroscientists of Africa meeting #SONA2025. It allowed me to present my work to researchers I wouldn’t typically have the opportunity to connect with. Def going to the next one too.

Our main goal was to show that CATCH is straightforward to implement. We detail how to design and apply CATCH in mice, integrating it with electrophysiology and behavioral assays.
If you’re interested in applying CATCH, or adapting it to your favorite receptor, feel free to reach out!

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! 🧭
