Our preprint is out! 🧠🎉 How can we watch a mammalian brain circuit assemble while preserving its native connectivity? Hindbrain explants let us follow the olivo-cerebellar circuit from before synaptogenesis through functional maturation at single-cell resolution. www.biorxiv.org/content/10.6...

Hindbrain explants enable multimodal and longitudinal analysis of the developing olivo-cerebellar circuit at single-cell resolution
Experimental models that preserve native mammalian CNS circuitry while enabling longitudinal analysis of circuit assembly at single-cell resolution remain scarce, limiting mechanistic studies and ther...

High-affinity detection of biotinylated endogenous neuroligin-1 at excitatory and inhibitory synapses using a tagged knock-in mouse | PNAS
Neuroligins (NLGNs) are important cell adhesion molecules mediating trans-synaptic contacts between neurons. However, the high-yield biochemical is...

Le 9 mars, un chercheur français du CNRS a été refoulé par les États-Unis alors qu’il se rendait à un congrès scientifique. L’Académie des sciences s’élève avec vigueur contre cette pratique qui met gravement en cause les libertés fondamentales du monde académique. urlr.me/fva3NE

Un chercheur français en mission pour le CNRS a été interdit d’entrer aux États-Unis et a été refoulé de l’aéroport, le 9 mars, au motif frauduleux qu’il avait exprimé une « opinion personnelle » sur la politique américaine en matière de recherche. www.humanite.fr/monde/admini...

If you are interested in synaptic plasticity, you probably know that Ras is important. But... which one? Would you have guessed that there is one Ras for potentiation and another one for depression? Check our latest publication in @embojournal.org doi.org/10.1038/s443... @cbm-csic-uam.bsky.social
