(A) Schematic summary of cortical GABA circuits describing the subcellular location and subunit-specificity of the receptors targeted by different GABA neuron subtypes. (B) Morphological and biochemical features of PV- and CCK-positive subpopulations of cortical GABA neurons in the DLPFC. The chandelier and basket neurons provide inhibitory input to the axon initial segment (ais) and the cell body and proximal dendrites, respectively, of pyramidal neurons. 1–4, layers of DLPFC.
