Visual Receptors and Transduction

Visual perception provides us with a wealth of information about the world around us. Eyesight enables us to perform essential activities, such as walking, reading, or driving a car, and its loss can have devastating effects on quality of life. Light enters our eyes and is focused by a lens at the back of the eye onto a thin layer of highly organized neurons forming the retina. The retina is the only visible part of our brain and is the organ that allows us to see. Within the retina, incident light is detected and transformed into an electric signal by specialized neurons called photoreceptors. This signal is then processed as it travels through the layers of retinal neurons and is eventually transmitted by the axons ...
