Two novel types of bistratified amacrine cells in the chick retina: a Golgi study

1. The correlation between neurotransmitter substances in specific cell types has renewed interest in the morphology of amacrine cells. In this paper we describe the morphology of two types of amacrine cells in Golgi-stained chick retinas. 2. The first cell type was classified as an asymmetric bistratified amacrine cell suggested to play a role in the formation of complex ganglion cell receptive fields. 3. The second was classified as a bistratified amacrine cell. Their processes were stratified at sublayers 1 and 4 of the inner plexiform layer and their morphological features were similar to those of dopaminergic cells in the chick retina.
