Hypothetical scheme of innervation patterns of VIP interneurons across cortical layers. A bipolar VIP neuron as the main subtype in superficial layers innervates dendrites of interneurons in all layers, in addition to subpopulations of local pyramidal cells. We hypothesize they also innervate dendrites of deep layer pyramidal cells (marked with question marks). The multipolar VIP interneurons in deep layers, some of which are likely small basket cells, preferentially form perisomatic synapses on both pyramidal cells and interneurons in deep layers. BP: bipolar; IN: interneuron; PYR: pyramidal cell; MP: multipolar.
