Definition & Meaning of "cortex"

What is "cortex"?

The cortex, also known as the neocortex, is a highly complex and layered structure that forms the outer surface of the brain. It is composed of billions of neurons and is responsible for many essential functions such as conscious awareness, perception, voluntary movement, and higher-level cognitive processes. The cortex is divided into different regions, each with specialized functions, such as the frontal lobe involved in executive functions and decision-making, the parietal lobe involved in sensory processing, the temporal lobe involved in memory and auditory processing, and the occipital lobe involved in visual processing. The intricate organization of the cortex allows for intricate connections and information processing, making it a critical component of the central nervous system.
