Here we go again! Grant writing during the summer break….feels like a yearly routine by now…

We wrote a French digest for médecine/sciences about our recent work in Nat. Neuro with @nicolasguyon.bsky.social Original work: www.nature.com/articles/s41... French piece: www.medecinesciences.org/fr/articles/...

Haven’t written science in French in years, but just published a short open-access commentary on my Nat Neuro work with @pierrelemerre.bsky.social. Hopefully useful for teaching in French-speaking contexts! You can find it here: doi.org/10.1051/meds... Original work: www.nature.com/articles/s41...

Looking for a postdoc (fast)!! 😅 2-years funded on the ATIP-Avenir Program. I'll be at #FENS2026 in Barcelona if you want to meet in person. www.fens.org/careers/job-...

So I (well Claude mostly) made a @julialang.org port of the ZETA test originally developped by Jorrit Montijn (published here: elifesciences.org/articles/71969). The port is faithful to zetapy (Python version by @guidomeijer.com and @alexanderheimel.bsky.social). Enjoy github.com/PierreLeMerr...

Dear colleagues, We are looking for a PhD candidate! Project co-directed by Centre de Recherche en Neurosciences de Lyon and by the Laboratoire de Mécanique et d'Acoustique (Marseille). Fully funded by Fondation Pour l'Audition (see link). Deadline April 30, 2026 www.abg.asso.fr/fr/candidatO...

Using Kandel et al., Principles of Neural Science as a stand for monitors is clearly a thing in the field right?

Activity-based maps of the prefrontal cortex in mice, presented in @natneuro.nature.com today, challenge classical descriptions of the brain. The new maps reveal functional territories that differ from traditional, tissue-based maps. #Neuroscience #Brain 🧪 news.ki.se/new-brain-ma...

It's out! Our new study (led by @pierrelemerre.bsky.social & @weltgeischt.bsky.social @carlenlab.bsky.social) challenges classical cytoarchitectonic borders in the prefrontal cortex, showing that connectivity better explains its functional organization.

We used rabies virus 👾 to map how #psilocybin modifies long-range circuits 🧠, revealing network-specific reorganization that we didn’t expect. The full study is now online at Cell. @cp-cell.bsky.social Paper 👉 www.cell.com/cell/fulltex... Thread for a synopsis 👉 bsky.app/profile/alex...

Data reuse represents an opportunity to accelerate science, reduce costs and increase the value of investments. But to date, the field hasn't placed equal emphasis on the reuse side of the data-sharing equation, writes @bendichter.com #neuroskyence www.thetransmitter.org/open-neurosc...

The main project from my PhD, in collaboration with Manuela Allegra and @schlab.bsky.social is now available as a preprint! We wondered how the hippocampus and the visual cortex may differ in the way they refine sensory inputs into internal representations

Task engagement differentially drives hippocampal and neocortical neural codes

Sensory inputs are progressively transformed into internal representations of the environment along the cortical hierarchy. How does the behavioral relevance of these inputs affect this encoding? Usin...

I am extremely grateful and beyond happy to share that I have been awarded an @inserm.fr #ATIP-Avenir fellowship to start my own lab to study neuronal circuits for auditory categorization! Thanks to everyone who made this possible.

In case this is helpful for anyone, here is a post on how to get a job in french academia : trialsanderrors.substack.com/p/getting-a-... Aimed at non-french scientists who are curious, but french ones may find it useful too.

Feeling pretty good today! I got accepted at CNRS (section 25)!! Congrats to the other candidates too!
