what does the telencephalon development from
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.
