Extended Data Fig. 7: Somatic versus dendritic synapses across all excitatory M-types.
From: Inhibitory specificity from a connectomic census of mouse visual cortex
a) Median number of dendritic and somatic synapses for excitatory neurons of all M-types. Pearson r = 0.96, p = 5 × 10−10. b) Number of dendritic and somatic input synapses across all excitatory neurons, colored by M-type. Pearson r = 0.86, p < 1 × 10−10. Black line indicates linear fit with 95% confidence intervals from bootstrapping. c) Individual ordinary least square fits (with 95% confidence interval) for each M-type of z-scored dendritic synapses vs z-scored somatic synapses. With the exception of L5NP cells and deep layer 6b L6wm cells, all M-types have a positive relationship between predominantly inhibitory somatic synapses and predominantly excitatory dendritic synapses. d) Number of dendritic vs somatic input synapses for each M-type separately, linear fit line and 95% confidence interval.
