Differential distribution of different classes of Necturus retinal ganglion cells. 1981

J R Tuttle

The responses of Necturus retinal ganglion cells were recorded extracellularly. Each cell was characterized by its response type and the distance between its receptive field center and the center of the optic disc. There was a statistically reliable difference between the locations of sustained-ON cell and the locations of sustained-OFF and ON-OFF cells. Thus, the different classes of Necturus retinal ganglion cells are differentially distributed across the surface of the retina.

D012160 Retina The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent. Ora Serrata
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.
