Light reflected from an object enters the eye and forms an image on the Trina. Receptors in the retina convert the image into nerve impulses, which travel along the optic nerve to the visual cortex. The route from the receptors to the visual cortex is called the visual pathways.
Reaching to light
The retina at the back of the eye is a layer of many thousands of light sensitive cells called receptors. Light falling in these receptors trigger them to release electrical impulses. The receptors in the retina are linked to a network of nerve cells in. The back of the eye. These in turn are linked to the nerve cells in the optic nerve. Impulses triggered by the receptors cells pass along this network to the visual cortex at the back of the brain.
