Prosencephalon Categories.

	Diencephalon - The paired caudal parts of the prosencephalon from which the THALAMUS; HYPOTHALAMUS; EPITHALAMUS; and SUBTHALAMUS are derived.
	Telencephalon - Paired anteriolateral evaginations of the prosencephalon plus the lamina terminalis. The cerebral hemispheres are derived from it. Many authors consider cerebrum a synonymous term to telencephalon, though a minority include diencephalon as part of the cerebrum (Anthoney, 1994).
