The brain stem of the midbrain links to the spinal cord, hindbrain, and forebrain, and is the network system that transmits nerve impulses to and from the brain and spinal cord. The cerebrum of the forebrain is where conscious motor activity, emotion, complex thought, and memory all take place. The brain also wraps over and connects to the hypothalamus, pituitary, and pineal glands. The brain stem is the lower part of the brain that includes the medulla oblongata, pons, and mesencephalon. It connects the brain to the spinal cord and the twelve pairs of nerves from the brain to the rest of the body branch off the brain stem.
