Development of the brain begins with the appearance of the brain vesicles in the early part of
the embryonic period. Evagination of the prosencephalon gives rise to the cerebral
hemispheres. The primitive hemispheres and lamina terminalis constitute the telencephalon
(endbrain). The diencephalon (epithalamus, thalamus and hypothalamic apparatus) is adjacent
to the IIIrd ventricle. The cerebellum develops from a projection into the IVth ventricle. The
nervous system dedelops from Dorsal ectoderm at the 16th day. The neural tube begins to
fuse at the end of the 3rd week. Rostral closure occurs on the 24th and caudal closure on the
26th day.
