Brain, cerebellum. Computer artwork of a human brain in profile within a glass-effect male head, showing the location of the cerebellum (red). The cerebellum is part of the hindbrain and is the control centre for motor function, including balance, posture, and muscle tone and activity. The cerebellum connects to the brainstem (bottom centre of the brain), which sub-consciously controls the body's vital functions, including breathing and blood pressure. The main part of the brain comprises the hemispheres of the cerebral cortex (upper centre), which are responsible for intelligent thought, language, memory and consciousness.
