Which part of the brain is responsible for relaying information between different sides of the brain?

The pons is a crucial structure in the brainstem that plays a key role in relaying information between the two hemispheres of the brain. It contains several pathways that connect the cerebellum with the cerebral cortex and also facilitate communication between the left and right sides of the brain. The pons is involved in a variety of functions, including the regulation of breathing and sensations, as well as playing a part in sleep and arousal.

The medulla oblongata, located just below the pons, is primarily responsible for regulating vital autonomic functions such as heart rate and breathing. While it is essential for basic life functions, it does not specifically serve the role of relaying information between the brain's hemispheres.

The cerebellum, located at the back of the brain, is mainly involved in coordinating voluntary movements, balance, and motor control. It does work with the pons to process information related to movement and coordination, but it does not directly relay information between the two hemispheres.

The spinal cord is a major pathway for transmitting messages between the brain and the rest of the body, but it does not have a role in connecting the two sides of the brain. Its primary function is to relay information to and from the brain concerning
