Embryologically, the diencephalon begins as the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures.
diencephalon. 1. the posterior part of the prosencephalon, consisting of the hypothalamus, thalamus, metathalamus, and epithalamus; the subthalamus is often considered to be a distinct division.See also brainstem.2. the posterior of the two brain vesicles formed by specialization of the prosencephalon in the developing embryo.tymology: Gk, di + enkephalon, brain. the portion of the brain between the cerebrum and the mesencephalon. It consists of the hypothalamus, thalamus, metathalamus, and the epithalamus and includes most of the third ventricle. , pl.
