Neurongenesis
Neurongenesis, more commonly spelled neurogenesis, is the process by which new neurons are generated from neural stem and progenitor cells. In the vertebrate brain, most neurons are formed before birth, during embryonic and early postnatal development, but a limited amount continues to be produced in certain regions of the adult brain.
In adult mammals, the principal sites of ongoing neurogenesis are the subgranular zone of the dentate gyrus
Lineage and development follow a general progression: neural stem cells give rise to intermediate progenitors, which
Regulation of neurongenesis is influenced by environmental and physiological factors. Physical exercise and environmental enrichment tend
The functional significance of adult neurogenesis, especially in humans, remains under investigation. In animals, it is
