Hi Blsky 🦋!
I'm a neuroscientist and fresh team leader at the Paris Brain Institute and INSERM
@karalis-lab.bsky.social we work at the interface of experimental, large-scale data analysis, and computational neuroscience, trying to understand the functional architecture of neuronal circuits.

Fascinating! And yet another proof of the level of complexity of neuronal circuits.
🧠 The Lipid #Brain Atlas is out now! If you think #lipids are boring and membranes are all the same, prepare to be surprised. Led by @lucafusarbassini.bsky.social with Giovanni D'Angelo's lab, we mapped membrane lipids in the mouse brain at high resolution.
