It is notable as being one of a select few brain structures known to have significant rates of adult neurogenesis in many species of mammals, from rodents to primates.[4] Other sites of adult neurogenesis include the subventricular zone, the striatum[5] and the cerebellum.[6] However, whether significant neurogenesis exists in the adult human dentate gyrus has been a matter of debate.[7][8] 2019 evidence has shown that adult neurogenesis does take place in the subventricular zone and in the subgranular zone of the dentate gyrus.[9][7]
