Visual System

Abstract

Awareness of the appearance of people and objects in the environment is made possible by the visual sensory system. Eyesight is a critical feature of adaptation to the environment, serving as the basis for registering key information about how people and things are arranged in space and time. The eye makes vision possible by transforming light energy into neural impulses that travel through sensory pathways to the central nervous system. When these impulses reach the cerebral cortex, they are further processed, serving as the basis for refined and integrated perceptual judgments.
