The human brain is divided into left brain and right brain, so what are they responsible for?

The upper side of the brain stem is connected with the cerebral hemisphere, and the lower side is connected with the spinal cord in an irregular column shape. Nerve impulses introduced into the brain through the spinal cord enter in a cross way: impulses from the right side of the spinal cord first pass to the left side of the brain stem and then to the brain; From the left side of the spinal cord, to the right side of the brain stem, and then to the brain. The function of brain stem is mainly to maintain individual life, including heartbeat, respiration, digestion, body temperature, sleep and other important physiological functions, all related to the function of brain stem.

The cerebellum is located under the brain and occipital lobe, just behind the brain stem, and is the second largest part of the brain. The cerebellum is composed of two hemispheres, with gray matter on the outside and white matter on the inside. Functionally, the movement of cerebellum and cerebral cortex controls the movement of muscles to adjust the balance of posture and body.

The forebrain belongs to the highest part of the brain and is the most complex and important nerve center in the human brain. The forebrain is divided into hypothalamus, hypothalamus, limbic system and cerebral cortex.
