Definition of Neurogenesis

Neurogenesis: The process by which new nerve cells are generated. In neurogenesis, there is active production of new neurons, astrocytes, glia, and other neural lineages from undifferentiated neural progenitor or stem cells. Neurogenesis is considered a rather inactive process in most areas of the adult brain.
