Convergence and divergence in the microcircuits composed of perisomatic region-targeting interneurons and principal cells in the BLA. Left, Similar numbers of PVBCs and CCK/CB1BCs converge on a PC in the BLA. In contrast, fewer AACs innervate the axon initial segment of single PCs (data from Veres et al., 2014). Right, The quantity of PCs targeted by singe BCs is comparable, while individual AACs innervate fewer PCs. The percentage refers to the fraction of PCs that are innervated by single interneurons within their axonal cloud.
