Bipolar and ganglion cells
WebJun 8, 2015 · One general categorization of retinal ganglion cells is to segregate them into tonically or phasically responding neurons, each conveying discrete aspects of the visual scene. Although best identified in the output signals of the retina, this distinction is initiated at the first synapse: between photoreceptors and the dendrites of bipolar cells.

F: … WebAmacrine cells (named by Cajal for their lack of an axon) lie in the inner retina and make connections with bipolar cells and ganglion cells. They exist in a wide variety of morphological types (Masland, 1988; Wässle and Boycott, 1991 ). With rare exceptions, little is known about their roles.
