The human brain is a complex organ that serves as the control center for the body. It is responsible for processing sensory information, regulating bodily functions, and enabling cognitive abilities such as thinking, learning, and memory. Comprised of billions of neurons, the brain communicates through intricate networks, allowing for rapid information exchange. In addition to its role in basic survival functions, the human brain is also the seat of emotions and personality. It is divided into several regions, each with specialized functions, including the cerebral cortex for higher-order thinking and the limbic system for emotional responses.
