Median raphe input to dorsal CA1 shapes VIP interneuron recruitment and novelty-guided spatial memory
Vasoactive intestinal peptide–expressing interneurons (VIP-INs) gate hippocampal inhibition during novel experience, but the long-range signals that engage these cells remain poorly understood. Here we identify median raphe (MnR) projections as a brainstem pathway that tunes dorsal CA1 VIP-IN recruitment through coordi...
