Examples

• The prosencephala is one of the three primary brain vesicles formed during early embryonic development.
• During neurulation, the prosencephala differentiates into the telencephalon and diencephalon.
• Damage to the developing prosencephala can result in significant cognitive and behavioral abnormalities.
• The prosencephala gives rise to the cerebral hemispheres, thalamus, and hypothalamus.
• In vertebrate embryos, the prosencephala appears as a distinct bulge at the anterior end of the neural tube.
