Nouvel article avec @ecoutureau.bsky.social ☺️ www.pnas.org/doi/10.1073/... Quand une récompense n'arrive pas, comment le cerveau nous permet de savoir s'il s'agit d'une malchance… ou d'un changement des règles du jeu ? On a suivi la trace d'un neuromodulateur, la noradrénaline, pour comprendre :

Very proud to share our most recent work, now out in @cp-cellreports.bsky.social 🎉🎉🎉 We show that brief noradrenergic signals in the orbitofrontal cortex, triggered by surprising rewards, support reversal learning and predict how quickly animals adapt. www.cell.com/cell-reports...

Orbitofrontal noradrenaline acts as an early gate for reversal learning

Piccin et al. find that surprising rewards trigger brief orbitofrontal noradrenergic bursts whose magnitude predicts reversal learning speed. Targeted manipulation of noradrenergic neurons projecting ...

New Dispatch in @currentbiology.bsky.social w/ @RobinPiquet & @dryacinetensaouti.bsky.social highlighting elegant work from the @iordanova.bsky.social lab that formally disentangles whether dopamine signals reward prediction errors or value. authors.elsevier.com/a/1ldGk3QW8S...

As Chair of the Bordeaux Neurocampus Parity and Inclusion Committee, I’m pleased to share we’ve received generous CNRS funding to expand our inclusion efforts. Thanks to @neurobordeaux.bsky.social and CNRS for the support, which enables us to keep building a more inclusive research environment.

🚨 New study alert! 🚨 Ever wondered if rats and humans learn in the same way? 🐭🧑‍🔬 We tested this — and the answer is yes, at least when it comes to how we value rewards in context. (with @shaunaparkes.bsky.social Lachlan Ferguson, Magdalena Soukupova) 🧵Thread 👇 1/ www.biorxiv.org/content/10.1...

Reference Point-Dependent Reinforcement Learning in Humans and Rats

Previous studies indicate that rewards and punishments in reinforcement learning are encoded in a relative manner. Reference point-dependence, a valuation bias shared by eminent adaptation level and p...

It's official! I've been awarded an #MSCA Postdoctoral Fellowship to work w/ @miriammelis.bsky.social in Cagliari 🏖️🇮🇹 #SPICE-FONTS will investigate the role of my fav neurotransmitter #noradrenaline in neurodevelopmental deficits caused by prenatal #cannabis exposure 🤰🌿 Grateful @ec.europa.eu 🙏🇪🇺

European Commission@ec.europa.eu · last yr.

The 2024 Marie Skłodowska-Curie Actions Postdoctoral Fellowship call results are in. With a budget of €417 million, we are funding nearly 1,700 researchers from 🇪🇺 and beyond. They will strengthen EU research in key areas such as social inclusion, AI, and cancer research ↓ europa.eu/!BmWRkh

Let's just say that when these experiments took place I had no idea where Wuhan was or how to change a diaper. So, you can just imagine how relieved I am to see this work out! A smooth and positive experience with the new @elife.bsky.social model, which I recommend.

Disruption of the CRF1 receptor eliminates morphine-induced sociability deficits and firing of oxytocinergic neurons in male mice

Both genetic and pharmacological studies reveal an essential role for the CRF1 receptor in social behavior deficits induced by a single morphine administration in male, but not in female, mice.
