AP PSYCHOLOGY

Detailed explanation-1: -On the other hand, the rods are absent from the fovea. At a few degrees away from it their density rises to a high value and spreads over a large area of the retina. These rods are responsible for night vision, our most sensitive motion detection, and our peripheral vision.

Detailed explanation-2: -Rods are a type of photoreceptor cell present in the retina that transmits low-light vision and is most responsible for the neural transmission of nighttime sight.

Detailed explanation-3: -There are two types of photoreceptors: rods and cones. Rods are responsible for peripheral vision, and are located outside of the central part of the retina. There are some 120 million of them, and they are responsible for night vision, because they are highly sensitive to low-intensity light.

Detailed explanation-4: -Which colors humans and other animals see depends on the light-sensing cells, or photoreceptors, in the eye. There are 2 types of photoreceptors: rods, which detect dim light and are used for night vision, and cones, which detect different colors and require brightly lit environments.
