The ganglion cell layer of the retina of the rat: a Golgi study
Abstract:
In whole-mounts of Golgi stained rat retinae four cell types are described in the ganglion cell layer. Three of these cell types are considered to be analogous to the alpha, delta and gamma cells described in the cat retina by Boycott & Wässle (1974). The fourth cell type is thoughtt to be a displaced amacrine cell. All the cell types described are present in all parts of the retina. There is no evidence for an increase in dendritic field size with increasing distance from the optic disk.

The Retina
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.
Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
