Figure 10: Schematic summary of the role of SAC-mediated control of active dendritic integration compartments of ON-DSGCs.

(a) SAC-mediated cholinergic excitation and GABAergic inhibition gate terminal dendritic integration to control action potential output under control conditions. (b) In the absence of cholinergic excitation terminal dendritic spike generation is weakly driven by bipolar cell-mediated excitation.
