RETINA

n. light-sensitive layer at the back of the eyeball which receives images and transmits them to the brain as nerve impulses (Anatomy)

For the moth genus, see Retina (moth). The retina is a thin layer of neural cells that lines the back of the eyeball of vertebrates and some cephalopods. It is comparable to the film in a camera. In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain. Hence, the retina is part of the central nervous system (CNS). It is the only part of the CNS that can be imaged directly.
