Input densities on the perisomatic and distal-dendritic compartments of VIP+ neurons. (A) The input densities to the apical and basal branches were pooled. Both VGluT1 and VGluT2 input densities were higher in the distal dendrites than in the somata and proximal dendrites (VGluT1 input, p < 0.0001; VGluT2 input, p = 0.0024 using one-way ANOVA). VGAT input density did not show significant differences among distances from the somata (p = 0.3231 using one-way ANOVA). PV inputs were more densely observed in VIP+ neuron somata than in their distal dendrites, whereas SOM inputs showed the opposite pattern (PV input, p < 0.0001; SOM input, p < 0.0001 using one-way ANOVA). The mutual connections among VIP+ neurons were few and VIP input density did not significantly differ among distances from the somata (p = 0.8961 using one-way ANOVA). The somatodendritic domain of VIP+ neurons could be divided by these innervation patterns at a distance of 100 μm from the somata into the “perisomatic” and “distal-dendritic” compartments. (B) Comparison of input densities to the perisomatic and distal-dendritic compartments. VGluT1 input, p < 0.0001; VGluT2 input, p < 0.0001; VGAT input, p = 0.9079; PV input, p < 0.0001; SOM input, p < 0.0001; VIP input, p = 0.3018 using two-tailed Student’s t-test. Six neurons from three mice for each input. Error bars, ± SEM. ***p < 0.001; n.s., not significant.
