Midbrain

Also known as the mesencephalon, the midbrain is a portion of the nervous system largely responsible for vision, hearing, motor control, sleep/wake, alertness, and temperature regulation. It is located just below the cerebrum and above the hindbrain, connecting the two portions. As the central production center of dopamine, it plays a major role in human functions. It is also found to some degree in even the most rudimentary and ancient vertebrates. It is considered the uppermost section of the brain stem.
