Fig. 3: Exploring pairwise connectivity of MET-types and postsynaptic targets.

a, Average histogram of percentage of each cell type that receives synapses as a function of radial (xz) distance between presynaptic EM cell and postsynaptic target. All distributions were compared pairwise by a Kolmogorov–Smirnov test with a false discovery rate correction. *P < 0.05 for all comparisons of that distribution to others. b, Percentage of connections that contain a single versus multiple synapses (shown up to five) for each target cell type across predicted MET-types (for example, predicted MET-6 cells form more multi-synaptic contacts onto L5 ET targets than onto other cell types). c, Example cell from each predicted MET-type showing soma locations of postsynaptic targets. Somas are colour-coded to indicate the number of synapses that cell receives from the presynaptic cell (soma in cyan). All examples use the same scale. d, Histograms of inter-synaptic distances onto target types (distances calculated per postsynaptic target). MET-8, -4 and -6 (n = 3, 6 and 5, respectively).
