The human brain is divided into four main lobes, along with the cerebellum and brainstem, each with vital functions. The frontal lobe controls reasoning, planning, problem-solving, emotions, and voluntary movement. The parietal lobe processes sensory information such as touch, temperature, pain, and helps with spatial awareness. The temporal lobe manages hearing, memory, and language comprehension, while the occipital lobe handles visual processing. The cerebellum coordinates balance, posture, and fine motor movements. The brainstem regulates vital automatic functions like heartbeat, breathing, and digestion.
