Neurogenesis is the combined processes of division, migration and differentiation neural stem cells (NSCs). The two different locations: subventricular zone (SVZ) lateral ventricle subgranular (SGZ) in hippocampus dentate gyrus (DG), provide a niche environment for neurogenesis. Neurotrophic factors have roles on migration, proliferation NSC progenitor cells. Studies shown that NSCs regulator...
