AP PSYCHOLOGY

Detailed explanation-1: -When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.

Detailed explanation-2: -When focused light is projected onto the retina, it stimulates the rods and cones. The retina then sends nerve signals are sent through the back of the eye to the optic nerve.

Detailed explanation-3: -The optic nerve is a bundle of more than 1 million nerve fibers. Also known as the second cranial nerve or cranial nerve II (CNII), it is the second of several pairs of cranial nerves. It transmits sensory information for vision in the form of electrical impulses from the eye to the brain.

Detailed explanation-4: -Posterior to the optic chiasm, the nerve fibres travel in optic tracts to various portions of the brain-predominantly the lateral geniculate nuclei. Fibres from the lateral geniculate nuclei form the optic radiations that course toward the visual cortex located in the occipital lobes in the back of the brain.
