Each hemisphere communicates with the other through the corpus callosum, which is a bridge of white matter. Small brain The cerebellum, or "cerebrum", is tucked under the cerebrum at the back of the head. It regulates balance and learned movements, such as walking and pressing buttons, but cannot initiate movement. Because the cerebellum is sensitive to alcohol, people will experience balance and gait problems.
When they drink too much. Recent New Zealand Email List research suggests that the cerebellum may also play a role in learning and decision-making. The cerebellum is an ancient part of the brain, and the cerebral cortex grew on top of it as humans evolved. Brain drain The brain stem consists of the midbrain, pons, and medulla. It connects the brain to the spinal cord.
The middle brain The midbrain is responsible for several important functions including hearing and movement. It also helps formulate responses to environmental changes, which include potential threats. Pons The pons enables a range of bodily functions, such as tear production, blinking, focusing of vision, balance and facial expressions. 10 cranial nerves emerge from the pons.
