The cerebrum plays a critical role in the human brain, responsible for higher brain functions such as thought, memory, and emotion. It is divided into two hemispheres and is involved in processing sensory information, controlling voluntary movement, and facilitating learning and reasoning. The cerebrum is covered by the cerebral cortex, which is further divided into lobes that specialize in different functions, such as the frontal lobe for decision-making and planning, and the occipital lobe for visual processing.
