midbrain

midbrain (mesencephalon) One of the three sections of the brain of a vertebrate embryo. Unlike the forebrain and the hindbrain, the midbrain does not undergo further subdivision to form additional zones. In mammals it becomes part of the brainstem, but in amphibians, reptiles, and birds the roof of the midbrain becomes enlarged as the tectum, a dominant centre for integration, and may include a pair of optic lobes.
