Two main neurogenic niches in the adult brain have been reported:
1. Ventricular-subventricular zone (V-SVZ)
2. Subgranular zone of the hippocampus (SGZ)
In addition to these two regions, adult neurogenesis has also been reported in regions like the striatum (Luzzati, et al., 2006, Luzzati et al., 2014) and cortex (Gould et al., 2001; Dayer et al., 2005).
