In prenatal development, the forebrain (prosencephalon) is the most anterior vesicle of the neural tube that later forms both the diencephalon and the telencephalon (which develops into the cerebrum).t consists of several structures between the brainstem and the cerebrum, including the thalamus, hypothalamus, epithalamus, pituitary gland, and pineal gland. Embryologically, the diencephalon begins as the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures.
Organs of the CNS are derived from the neural fold tissue (anterior= brain, posterior= spinal cord) As soon as the neural tube is formed, the anterior portion expands quicker than posterior, forming the primary brain vesicles: Prosencephalon (forebrain), Mesencephalon (midbrain), and Rhombencephalon (hind brain). The primary brain vesicles differentiate into secondary brain vesicles which further develop into functional adult structures: Diagram.
