The complete connectome for class AII glycinergic ACs in the mammalian retina. The connectome shows four modes of excitation (solid arrows), three modes of coupling (lines), five modes of GABA inhibitory input (open arrows), and four glycine inhibitory output modes (double arrows). CBa, OFF cone BCs; CBb, ON cone BCs; WF, wide field ON cone BCs; RB, rod BCs; TH1, class 1 dopaminergic axonal cells; α, alpha GCs; δ, delta GCs; pAC, peptidergic GABAergic AC; OFF AC1, dominant monostratified OFF cone AC population; OFF AC2, minor monostratified OFF cone AC population; ON AC, dominant monostratified ON cone AC population; ON SAC, ON starburst amacrine cell; AI-S2 subclass S2 class AI rod-dominated GABAergic AC. Some of the groups can be further weighted. For example, though ON cone BCs classes (there are at least five) are coupled to AII cells via gap junctions, they differ in their gap junction areas and one class (WF ON cone BCs) is also pre-synaptic via ribbon synapses.
