Displaced amacrine and ganglion cells in the newt retina

The inner nuclear layer and ganglion cell layer of the newt retina contain taurine- and GABA-accumulating cells which are located immediately adjacent to the inner plexiform layer. Transport studies with horseradish peroxidase (HRP) indicate the presence of displaced ganglion cells within the inner nuclear layer of the retina. These are more numerous at the periphery of the retina and constitute about 2.5% of the retinal ganglion cells. …
