Home > Blossary: Neurogenesis
Neurogenesis is the process by which neural cells (neurons and glial cells) are generated. Neurogenesis is most active during pre-natal development, and it is responsible for populating the growing brain with neurons and glial cells. Recently neurogenesis was shown to continue in several small parts of the brain of adult mammals: the hippocampus and the subventricular zone.

Stem cells can divide asymmetrically to self-renew whilst also producing differentiating daughter cells. In the early mammalian cerebral cortex, neuroepithelial cells divide symmetrically to rapidly ...

The ventricular zone is the place where cortical neurons are generated. It is located next to the ventricles. At first, this zone contains "progenitor" cells, which divide to produce neurons and ...

The subventricular zone is an area, located between the ventricular and intermediate zones in the fetal forebrain, in which neurons of the cerebrum are generated. The subventricular zone of the ...

The neural tube is the precursor to the central nervous system of the vertebrate embryo, which comprises the brain and the spinal cord. The neural groove gradually deepens as the neural folds ...

Inheritance of the basal process has been linked to cell fate specification. For symmetric divisions that expand the progenitor pool at the onset of neurogenesis, the basal process of ...

The neural plate is a key developmental structure that serves as the basis for the nervous system. Opposite the primitive streak in the embryo, ectodermal tissue thickens and flattens to become the ...

Adult neurogenesis, a process of generating functional neurons from adult neural precursors, occurs throughout life in restricted brain regions in mammals. These are the dentate gyrus of the ...
