Question

Quizplus · Accepted Answer

The area of the retina that is 20 degrees from center is known as the peripheral retina, which is responsible for detecting movement and dim light. This is due to the large number of rods present in this area, which are more sensitive to light than cones and are responsible for detecting motion and low-light conditions. Phosphenes are perceived flashes of light, stereocilia are tiny hair-like projections on sensory cells, and while cones are important for color vision, they are not as useful for detecting movement in low-light conditions as rods.
