Selective inhibitory control of pyramidal neuron ensembles and cortical subnetworks by chandelier cells.

ABSTRACT: The neocortex comprises multiple information processing streams mediated by subsets of glutamatergic pyramidal cells (PCs) that receive diverse inputs and project to distinct targets. How GABAergic interneurons regulate the segregation and communication among intermingled PC subsets that contribute to separate brain networks remains unclear. Here we demonstrate that a subset of GABAergic chandelier cells (ChCs) in the prelimbic cortex, which innervate PCs at spike initiation site, selectively control PCs projecting to the basolateral amygdala (_BLAPC) compared to those projecting to contralateral cortex (_CCPC). These ChCs in turn receive preferential input from local and contralateral _CCPCs as opposed to _BLAPCs and BLA neurons (the prelimbic corte
