title: [Stratification in the central nervous system].
abstract: In the authors' opinion the neuroblasts (glioblasts respectively) are moving along an oxigen-gradient, out of the proliferative layers toward the source of O2 (the vascular plexi). Stratigenesis is influenced by "guiding structures" (fibrillar plate in the tectum opticum), by the elongations of ependymal cells and by the similarly oriented vascular-connectives.
