Detailed explanation-1: -Rod and cone photoreceptors are specialized neurons that function in the initial step of vision. These light-sensitive cells lie at the back of the retina adjacent to the retinal pigment epithelium (RPE), a cell layer that is vital for the survival of photoreceptors.
Detailed explanation-2: -Photoreceptors are specialized neurons found in the retina that convert light into electrical signals that stimulate physiological processes.
Detailed explanation-3: -To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell’s membrane potential. There are currently three known types of photoreceptor cells in mammalian eyes: rods, cones, and intrinsically photosensitive retinal ganglion cells.
