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 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 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 ...

Radial glial cells are a widespread non-neuronal cell type in the developing CNS of all vertebrates examined so far. They were first identified as a transient population that serves as a scaffold for ...

A postmitotic neuron is a neuron that has exited the cell cycle. After exiting the cell cycle, cells are considered immature neurons. Postmitotic neurons undergo the process of neuronal ...
