What is the outermost layer of the cerebrum known as?

The outermost layer of the cerebrum is known as the cerebral cortex. This layer is critical because it plays a significant role in various high-order brain functions, including perception, reasoning, decision-making, and memory. The cerebral cortex is composed of gray matter, which contains the cell bodies of neurons, and it is involved in processing information from the senses, as well as in controlling voluntary movement.

Its structure includes various regions that are specialized for different functions, such as the frontal lobe, which is involved in executive functions and planning; the parietal lobe, responsible for sensory integration; the occipital lobe, which processes visual information; and the temporal lobe, which is associated with auditory information and memory. Understanding the role and structure of the cerebral cortex is essential for comprehending how complex cognitive processes are carried out in the brain.
