Relier le comportement aux signaux externes : une fonction intégratrice de l’hippocampe

Face au danger, le cerveau doit reconnaître les signaux de menace et élaborer une réponse adaptée.

Everyone knows dorsal and ventral hippocampus do different things. But how do neurons in these regions differ in function — and how are their contributions integrated? We tackled this with @noehamou.bsky.social and Sid Wiener in a paper just out in @pnas.org 👇🧵 1/12 www.pnas.org/doi/abs/10.1...

I am more than pleased to share our new work with you: "Intra- and Interhemispheric Signatures of Criticality at the Onset of Synchronization" biorxiv.org/content/10.6... Short 🧵 1/9:

Intra-and Interhemispheric Signatures of Criticality at the Onset of Synchronization

The cerebral cortex must flexibly alternate between locally segregated activity that supports specialization and long-range interactions that enable integration. How cortical networks balance these co...

New preprint out! How does criticality propagate from local neuronal circuits to whole-brain dynamics? We tackle this with a multiscale, connectome-based mouse model @ldallap.bsky.social . 🧵/n 👉 biorxiv.org/content/10.6...

Cell assemblies are drawing increasing attention in neuroscience, but one could argue that they are just an epiphenomenon. Is the activity of cell assemblies relevant for the brain? The short answer is yes. The long answer is in our paper, now online at PLOS Biology. 🧵👇 1/10 doi.org/10.1371/jour...

Adaptive communication between cell assemblies and “reader” neurons shapes flexible brain dynamics

Cell assemblies have been proposed as key units of brain activity, underlying diverse functions, but their basic features are not well understood. This study shows that interactions between cell assem...

🧠📢 New preprint alert Large-scale ephys is exploding but spike sorting remains the computational bottleneck. A 2-hr, 6-probe Neuropixels 2.0 Quad Base session can take over a week to sort on a single machine. Here's a better solution. 🧵 #neuroskyence #compneurosky

Let’s use a good occasion to break my Bluesky shyness 😅 — a new article just came out! This one goes back to data from the very start of my PhD, and I’m so happy to see it finally published 🧠 👉 onlinelibrary.wiley.com/doi/full/10.... 🧵1/5
