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.

Fantastic new work from our very own @alegrecortes.bsky.social !

Stay tuned for even more cool stuff!

I'm excited to share my latest publication! 🚨
Global and local nature of cortical slow waves:
www.cell.com/iscience/ful...

In brief, we explored in silico how cortical slow waves are shaped by both external inputs and intrinsic properties of neuronal populations.

Global and local nature of cortical slow waves

Explaining the macroscopic activity of a neuronal population from its microscopic properties poses a great challenge, not just because of the many local agents that play a role, but due to the impact ...

We will continue sometime soon with the 2nd #ParisCircuitDynamics conference.
Stay tuned!

And for the final talk of the conference, Karim Benchenane is sharing the latest on the role of breathing in coordinating neuronal dynamics during fear behavior.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

Then @gisellavetere.bsky.social gave us a nice summary of the current state-of-the-art on how memory engrams control behavior

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

And now Rebecca Piskorowski is telling us how hippocampal CA2 circuits are involved in social memories!

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

We continue with @thomasandrillon.bsky.social who is telling as about the phenomenology and mechanisms of local and global sleep states.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

And now we have 4 exciting short talks from our young investigators, going all the way from memory to molecules, through oscillations and computational modelling!

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

And after lunch, we resumed with @ggirardeau.bsky.social who told us about the role of amygdala in memory consolidation.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

Intense discussions continued during lunch and the poster session!

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

And just before the break, Michael Zugaro is giving a broad perspective on the music and orchestration of neuronal assemblies.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

Following this, Alain Destexhe explained to us how detailed biophysical modeling of neuronal networks can help us understand oscillatory dynamics.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 29

Day 2 of the 1st #ParisCircuitDynamics conference begins with @antsiro.bsky.social giving us an impressive broad and deep overview of gamma oscillations in hippocampal and thalamocortical circuits!

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 28

And for the final talk of the day, Nelson Rebola is talking to us about the diversity of interneurons and the role of dendritic integration in controlling cortical inhibition.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 28

Now, Stefan Remy is talking to us about how the medial septum influences hippocampal circuits during locomotion.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 28

Then Alberto Bacci talked to us about the consequences of dendritic inhibition and over-inhibition of cortical circuits.

Nikolas Karalis @nikolaskaralis.bsky.social · Apr 28

And off we go!

First talk of the 1st #ParisCircuitDynamics conference by Prof. David Dupret on how neuronal assemblies make memories!
