Fig. 4: Bipolar cell types innervating VG3s.

a Side view of example of each bipolar cell type innervating VG3 plexus. b Top down views of bipolar cell types innervating VG3 plexus. c Example of terminal homotypic touches that helped to group bipolar cells of the same type together. d Percent of bipolar input from each bipolar cell type innervating VG3 plexus (large pie chart) and each individual VGC (small pie charts). e Depth distribution of bipolar cell types according to Eyewire (colored traces) relative to our reconstructed VG3s (black histogram). f Observed number of each type of bipolar cell synapses innervating VG3s (red) relative to Monte Carlo prediction (black) that was based on the arbor overlap in (e) and data in (d) (424 synapses from 6 VG3s).
