Brain Formation

•  The anterior part of the neural tube expands to form the brain

During embryonic development, the neural tube will enlarge and develop into different components of the nervous system:

  • The anterior part of the neural tube will expand to form the brain during cephalisation (development of the head)
  • The remainder of the neural tube will develop into the spinal cord
  • Cells that comprised the neural crest will differentiate to form most of the peripheral nervous system

The embryonic brain will initially be composed of three primary structures – the forebrain, midbrain and hindbrain

  • These structures will eventually give rise to the identifiable components of the developed brain
