Rod and Cone Pathways in the Inner Plexiform Layer of Cat Retina

Abstract

In cat retina, rod bipolar terminials do not synapse on ganglion cells but on two types of amacrine cell (types I and II). Cone bipolars synapse directly on ganglion cells and on type I amacrines. The type II amacrine appears to play a special internuncial role between bipolars and ganglion cells in the rod system.
