Brain vesicles are the bulge-like features of the early development of the neural tube, Three vesicles form at the first stage, which are called primary vesicles, Forebrain/Prosencephalon, Midbrain/Mesencephalon, and Hindbrain/Rhombencephalon. the brain continues to develop, and the vesicles differentiate further, the three primary vesicles become five secondary vesicles,Telencephalon, Diencephalon, Mesencephalon, Metencephalon, and Myelencephalon

Telencephalon: cerebral cortex, basal ganglia (caudate, putamen, globus pallidus), basal forebrain nucleus, hippocampus

Diencephalon: thalamus, hypothalamus, posterior pituitary, retina
