Distinct rod and cone pathways of rod BC inhibition. A: in dark-adapted retinas where rod pathways are active, rod BCs receive significant inhibition, likely from A17 ACs (white), and little inhibition from cone-activated pathways (dark gray). B: when rod pathways (dark gray) were saturated with an adapting background, inhibition from the cone pathway (white) was suppressed by inhibitory connections between GABAergic ACs, resulting in little inhibition to rod BCs.
