prosencephalon

 [pros″en-sef´ah-lon]
1. the portion of the brain developed from the anterior of the three primary brain vesicles in the early embryo, comprising the diencephalon and telencephalon.
2. the most anterior of the primary brain vesicles; called also forebrain.

pros·en·ceph·a·lon

(pros'en-sef'ă-lon), [TA]
The anterior primordial cerebral vesicle and the most rostral of the three primary brain vesicles of the embryonic neural tube; it subdivides to form the diencephalon and telencephalon.
Synonym(s): forebrain vesicle ☆ , forebrain ☆ , proencephalon

forebrain

that part of the brain which gives rise to the CEREBRAL HEMISPHERES, olfactory lobes, the PINEAL GLAND, PITUITARY GLAND and the OPTIC CHIASMA (which carries nerve fibres from the eyes to the midbrain). It is marked by a constriction in the developing embryo where the brain appears to be three-lobed, the forebrain, MIDBRAIN and HINDBRAIN.
