vCA1 SST neurons represent avoidance states that guide anxiety-related behavioral choices https://www.biorxiv.org/content/10.64898/2026.03.02.709156v1
New preprint from the lab. @markgergues.bsky.social and crew show that the PVT gates ventral hippocampal salience coding, shifting output between threat- and reward-weighted representations during associative learning and anxiety-related behavior.

Come to our symposium tomorrow morning at #NeuroFrance2025 if you want to hear about extero- and interoceptive impact on emotions!
A much-needed joint effort from five labs to see which behavioral effects of psilocybin in mice are reliable, and which may be spurious 🐁🍄

Sharing a new paper from the lab. This paper, led by Sangyoon Ko, represents a merging of two longstanding research themes in the lab-- adult neurogenesis and systems consolidation.

A short thread follows for those interested.

New work! Learning is assumed to involve synaptic plasticity, but which specific synapses change to enable higher order cognitive functions? We actually find that cognitive flexibility involves potentiation of long-range GABAergic synapses from prefrontal PV neurons: www.biorxiv.org/content/10.1...
