Figure 4. Divergence of bipolar cell output to ganglion cell types.

Putative connections between each bipolar cell type and the ganglion cell types described in the connectome (Helmstaedter et al. 2013). Type 6, 7, 8 and 9 ON cone bipolar cells have major connections with the GC 12 A-type ON ganglion cell. All other bipolar cell types diverge to multiple ganglion cell types. The rod bipolar cell does not have connections exceeding 1% with any of the ganglion cells. The amount of overlap between each pair is normalized by each bipolar cell type's total connectivity.
