Some of the types of amacrine cell present in the rabbit retina. This is a subset of the total population of amacrine cells distinguishable in photofilling and Golgi stains. In the initial study, 29 types of amacrine cell were identified.37,38 Later work62 indicated that the number of types of wide-field amacrine cells had been underestimated, because a small number of wide-field cells of any one type can still blanket the retinal surface completely, and they are thus rarely encountered by any sampling method. Note that many of the amacrine cells shown here violate the division of the inner plexiform layer into ON (inner) and OFF (outer) halves: They carry ON information to the OFF cells, and OFF information to the ON cells.
