How light enters the retina and is transmitted out the optic nerve This animated cartoon illustrates how light (white dot)enters the retina on the side containing the optic nerves and travels through all of the retinal layers before finally being absorbed by the photopigments in the outer segments of the receptors. A neural signal (yellow dot)is generated in the receptors which then travels through the neurons of the various retinal layers and finally travels out through the optic nerve up to the lateral geniculate nucleusThis animated cartoon illustrates how light (white dot) enters the retina on the side containing the optic nerves and travels through all of the retinal layers before finally being absorbed by the photopigments in the outer segments of the receptors.
