Figure 4.
Distributions of the three positional classes of basal synapses for the five OFF bipolar cell types. The dendrites (pale red) of the five types of OFF bipolar cells form basal synapses with cone pedicles (different colors with serial pedicle numbers). The synaptic contacts are categorized according to their basal positions as TA (magenta square), middle NTA (yellow circle), and marginal NTA (cyan triangle).
