The primary function of the cerebral cortex is to process and integrate sensory information, and it plays a vital role in higher cognitive functions such as thought, memory, and decision-making. The cerebral cortex is divided into different regions, each associated with specific functions, including sensory perception, motor control, language, and emotional regulation. It enables individuals to interact with their environment, solve problems, and perform complex tasks. Overall, the cerebral cortex is essential for human intelligence and behavior.
