WebA retinal ganglion cell is a type of neuron located near the inner surface of the retina of the eye. It receives visual information from photoreceptors via two intermediate neuron … 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. Some amacrine cells might have little to do ...
