![]() Once born, neurons do not divide (see mitosis), and many will live the lifespan of the animal, except under extraordinary and usually pathogenic circumstances. Neurogenesis is most active during embryonic development and is responsible for producing all the various types of neurons of the organism, but it continues throughout adult life in a variety of organisms. Types of NSCs include neuroepithelial cells (NECs), radial glial cells (RGCs), basal progenitors (BPs), intermediate neuronal precursors (INPs), subventricular zone astrocytes, and subgranular zone radial astrocytes, among others. This occurs in all species of animals except the porifera (sponges) and placozoans. ![]() In short, it is brain growth in relation to its organization. ![]() Neurogenesis is the process by which nervous system cells, the neurons, are produced by neural stem cells (NSCs).
