Abstract：
:The morphology, dendritic stratification and laminal position of the soma of retinal ganglion cells were analyzed in Golgi preparations and in other rabbit retinas containing cells backfilled from the superior colliculus. Only one type, among 40 Golgi-impregnated types identified, always had its cell body displaced to the amacrine cell sublayer of the inner nuclear layer. The displaced ganglion cell of rabbit retina has a small cell body, very wide dendritic field with sometimes unbranched dendrites extending up to a millimeter from the cell body. The dendritic tree is narrowly stratified just under the amacrine cell bodies in stratum 1, and therefore does not co-stratify with starburst (cholinergic) amacrine cells, but rather with dopaminergic amacrine cells. Its correlate among ganglion cells backfilled from tectum is apparently a very sparse population of small-bodied cells mixed with a variable population of misplaced ganglion cells of varying size and type. The authentic displaced ganglion cell of rabbit retina, unlike the large displaced ganglion cell of birds, is apparently not a directionally selective ganglion cell, and its functional role in vision is presently unknown.
