«Neurogenesis is the process by which nervous system cells, known as neurons, are produced by neural stem cells (NSC)s, and it occurs in all species of animals except the porifera (sponges) and placozoans. Types of NSCs include neuroepithelial cells (NECs), radial glial cells (RGCs), basal progenitors (BPs), intermediate neuronal precursors (INP)s, subventricular zoneastrocytes, and subgranular zone radial astrocytes, among others. Neurogenesis is most active during embryonic development, and is responsible for producing all the various types of neurons of the organism, but continues throughout adult life in a variety of organisms. Once born, neurons do not divide (see mitosis), and many will live the lifetime of the animal.» (wikipedia)
