• Nervous System Regionalization Entails Axial Allocation before Neural Differentiation "Neural induction in vertebrates generates a CNS that extends the rostral-caudal length of the body. (edu.au)
  • The postcloacal gut had completely disappeared at stage 18 , and multiple cavities of the caudal neural tube were clearly visible. (edu.au)
  • The neural closure extends a short distance caudal to the last somite, to the level of the otic segment ofthe hindbrain. (ehd.org)
  • In addition, groups of mesodermal cells located alongside the neural tube, called somites, will develop into skeletal muscle, vertebrae, and the dermal layer of the skin (Fig. 2-1D). (wrhhs.org)
  • In the less advanced specimens the neural groove is open throughout its whole length, whereas by the end of the stage the groove is closed from the rhombencephalon to below the level of the last somites present. (ehd.org)
  • To test this model, we used chromatin accessibility to define how cells adopt region-specific neural fates. (edu.au)
  • Together with genetic and biochemical perturbations, this identified a developmental time window in which genome-wide chromatin-remodeling events preconfigure epiblast cells for neural induction. (edu.au)
  • Contrary to the established model, this revealed that cells commit to a regional identity before acquiring neural identity. (edu.au)
  • Note also the cells formed from differentiated cells of the neural crest (D). (See text for details. (wrhhs.org)
  • Development of the neural crest and sensory systems (hearing/vision/smell) are only introduced in these notes and are covered in detail in other notes sections. (edu.au)
  • These findings prompt a revision to models of neural induction and support the proposed dual evolutionary origin of the vertebrate CNS. (edu.au)
  • Induction of neural tissue requires inhibition of the gene for a so-called bone morphogenetic protein, or BMP. (blogspot.com)

  • This animation shows early neural development from week 3 onward. (edu.au)
  • Neural development is one of the earliest systems to begin and the last to be completed after birth. (edu.au)

  • Gyri and sulci create the folded appearance of the brain in humans and other mammals . (wikipedia.org)
  • Polymicrogyria (meaning "many small gyri") is a developmental malformation of the human brain characterized by excessive folding of the gyri and a thickening of the cerebral cortex . (wikipedia.org)
