The brain is the command center of the nervous system. It’s a complex organ responsible for processing information received from the sensory organs, controlling body movements, regulating physiological functions, and much more. Structurally, it consists of billions of neurons, which are specialized cells that transmit information via electrical and chemical signals. The brain is divided into various regions, each with specific functions, such as the cerebral cortex for higher cognitive functions, the cerebellum for coordination and balance, and the brainstem for basic life-sustaining tasks like breathing and heart rate regulation. The brain plays a crucial role in virtually all aspects of human experience and behaviour.
