I’m pleased to share our new paper, “Hippocampal ripple diversity organizes neuronal reactivation dynamics in the offline brain”, out in @cp-neuron.bsky.social !

With @vitorlds.bsky.social and David Dupret, we show that diversity in ripple current profiles shapes reactivation dynamics

"The lack of full-bodied locomotion and extensive exploratory behaviors in head-fixed paradigms indicates that in our experimental setup the behavioral state is not directly analogous to the preparatory and consummatory phases seen in freely moving tasks."

Nicotine doesn’t just “turn on” the brain’s reward circuits — it reshapes them. Our new paper in Nature Communications shows that activating reward-linked dopamine neurons also sets off a feedback loop that drives negative emotional states.
