Getting ready for #FENS2026 at Barcelona? Our lab will be there with 7 posters and a symposium. fens2026.neuronaldynamics.eu Come by our posters 611 - 617 on Thursday morning to learn the latest about neuromodulators and how they organize neural activity and computation. @fens.org

Happy and proud of being part of this super team! Thanks to @embo.org and @frm-officiel.bsky.social for their support and super congrats to @alegrecortes.bsky.social! Cool science is on the way!

Thought this would be a nice way to enter the bsky community👇Delighted for Katie (now in Chris Dulla's lab at Tufts). Thank you to our collaborators, to the reviewers and to Cagla Eroglu for the highlight! www.science.org/doi/10.1126/...

Norepinephrine signals through astrocytes to modulate synapses

Locus ceruleus (LC)–derived norepinephrine (NE) drives network and behavioral adaptations to environmental saliencies by reconfiguring circuit functional connectivity, but the underlying synapse-level...

Moving to Paris to start a postdoc in the Neuronal Circuits and Brain Dynamics lab joining the amazing team of @nikolaskaralis.bsky.social Great people and cool science awaits, I am excited and grateful in equal parts... @karalis-lab.bsky.social, INSERM and Paris Brain Institute here we go ✈️😊

An #astrocytic ensemble that emerges in the nucleus accumbens upon activity during cue-motivated behaviors and is essential for modulating cue-reward associations 🧪🧪 www.nature.com/articles/s41...

Astrocyte ensembles manipulated with AstroLight tune cue-motivated behavior - Nature Neuroscience

Using the AstroLight system, the authors reveal that astrocytic ensembles in the nucleus accumbens regulate cue-motivated reward behavior, demonstrating that selective manipulation of tagged astrocyte...
