Brain Development

What is the neural tube?

The neural tube is a long tubular structure that develops from the outer layer of the initial plate of embryonic cells. At the head of the neural plate, three bulges form distinct sections. These are called the forebrain, the midbrain and the hindbrain, also known as the prosencephalon, the mesencephalon, and the rhombencephalon. The table below lists the parts of the neural tube.

Neural Tube Regions   Final Brain Regions
Hindbrain Metencephalon Pons
Myencephalon Medulla Oblongata
Midbrain Tectum Inferior Colliculus
Superior Colliculus
Cerebral Peduncle Various Neurotransmitter Cell Bodies
Forebrain Diencephalon Hypothalamus
Other Thalamic Regions
  Telencephalon Neocortex
Limbic System
Basal Ganglia
Cerebral White Matter
