In the anatomy of the brain of vertebrates. the prosencephalon (or forebrain ) is the rostral -most (forward-most) portion of the brain. The prosencephalon, the mesencephalon (midbrain), and rhombencephalon (hindbrain) are the three primary portions of the brain during early development of the central nervous system .

At the five-vesicle stage, the prosencephalon separates into the diencephalon (prethalamus, thalamus. hypothalamus. subthalamus. epithalamus. and pretectum ) and the telencephalon ( cerebrum ). The cerebrum consists of the cerebral cortex. underlying white matter. and the basal ganglia .

When the embryonic prosencephalon fails to divide the brain into two lobes, it results in a condition known as holoprosencephaly .
