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.

14 Sept

It's happening this Wednesday and Thursday!

Join us today at 15.40 (Hall H) for our symposium @fens.org #FENS2026 on "Breathing as a dynamic scaffold of learning, emotion, and neural dynamics"! With talks from Adriano Tort, Miriam Nokia, Sophie Bagur, and @nikolaskaralis.bsky.social fens2026.abstractserver.com/program/#/de...

Misha Singh focuses her attention on how norepinephrine is distinctly controling arousal and beyond during spatial navigation and rule-updating (PS05-09AM-612).

For a summary of our abstracts, have a look at fens2026-abstracts.onrender.com

Pierre Boulet will teach you all about how to identify motifs and patterns in your data using our novel unsupervised scale-aware multi-dimensional motif discovery framework (PS05-09AM-617).

Devyani Sarin will share her results on the distinct dopaminergic modulation of the hippocampus and prefrontal cortex during spatial navigation and rule-updating (PS05-09AM-611).

@fe-rox.bsky.social will tell you all about how we can use low-rank RNNs and dynamical systems analysis to understand the attractor landscape in the prefrontal cortex and how norepinephrine shapes this landscape to control cortical computation (PS05-09AM-614).

Enia Ardid will present her novel work on data-driven training and parameter inference for large-scale biophysical models to study the receptor level mechanisms of neuromodulatory influence (PS05-09AM-615).

@ireneserrahu.bsky.social will present her amazing data using multiplexed recordings on how neuromodulators influence prefrontal neurons and astrocytes during complex behavior and decision making (PS05-09AM-614).

@alegrecortes.bsky.social is presenting his tour-de-force dissection of the complex interactions between norepinephrine and acetylcholine to shape neuronal dynamics, using data analysis, mean-field modeling, dynamical systems analysis, and detailed biophysical modeling (PS05-09AM-613).

That's a true tour de force! Extremely challenging experiments at the cutting edge of current tech to answer a fundamental question of neural computation.

1/7 🧠 My journey into development begins with this work and question: how does the brain's spatial navigation system develop? We found that the neural networks for spatial navigation (tori and rings) are preconfigured and only later anchor gradually to the world with experience! 🧵

1 Mar

I’m building a foundational reading list for our lab (systems & circuit neuroscience, compneuro, modeling, neuromodulators, population coding etc.). I’d like to crowdsource recommendations. Which review(s) would you consider mandatory reading for the next generation of researchers?

Exciting news! @alegrecortes.bsky.social received the MSCA postdoc fellowship from @ec.europa.eu and @ireneserrahu.bsky.social has received the EMBO and FRM fellowships (@embo.org, @frm-officiel.bsky.social) to support their ambitious projects! Multiple open positions to join this super team!

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. www.biorxiv.org/cgi/content/...
