The primary function of the sensory cortex is to process sensory information from various parts of the body. This area of the brain is responsible for receiving signals from the five senses: sight, sound, touch, taste, and smell. Each type of sensory information is handled by specific regions within the sensory cortex. For instance, the visual cortex processes visual stimuli, while the auditory cortex deals with sound. This processing allows individuals to respond to environmental stimuli appropriately, contributing to perception and overall sensory experience.
