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.

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 ...

Astrocytes are specialized glial cells that outnumber neurons by over fivefold. They contiguously tile the entire central nervous system (CNS) and exert many essential complex functions in the ...

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 ...

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 ...

An increase in cell cycle length, specifically G1 phase, is naturally associated with the progression of neurogenesis. A recent model, referred to as 'cell cycle length hypothesis', has been ...

Besides radial glial cells, another type of neuronal progenitor cell—the basal or intermediate progenitor cells—emerges at the onset of peak neurogenesis. They accumulate in the subventricular zone, ...

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 ...
