Figure 5.

Abundance of each basal synapse class over the entire cone area for each OFF bipolar cell type. A group of OFF bipolar cells of the same type form basal synapses (TA in rectangles, middle NTA in ellipses, and marginal NTA in triangles) with a layer of cone pedicles. The first five members of each DB type are designated by the same colors as in Figure 2. Six central pedicles (26, 28, 32, 36, 39, and 41) are designated in gray for reference.
