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.

The subgranular zone (SGZ) is a brain region in the hippocampus where adult neurogenesis occurs. It is one of the two major sites of adult neurogenesis in the brain, along with the subventricular ...

In developmental biology, cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Neuronal differentiation means the acquisition of specific ...

The oligodendrocyte or oligodendroglia is a type of cell in the central nervous system (CNS). The oligodendrocytes surround and insulate the long fibers (axons) through which the nerves send their ...

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 ...
