Is there human adult neurogenesis?
There is ongoing debate regarding the existence of adult neurogenesis in humans. Some studies suggest that adult human neurogenesis occurs in the dentate gyrus and subventricular zone, albeit at varying levels of intensity . However, other studies argue that adult neurogenesis in the human brain is improbable and not detectable . The discrepancies in findings may be attributed to methodological variabilities and limitations in studying adult human neurogenesis . Further research is needed to standardize methodologies and increase the availability of post-mortem human brain samples to advance our understanding of adult human neurogenesis. It is important to note that the focus of research should be on the preservation of existing neurons rather than their replacement .

20 Jul 2021 | Yes, the paper confirms that adult human neurogenesis occurs in an intensity ranging from practically zero to a level comparable to adult mammalian neurogenesis in general. |
33 Citations | The paper suggests that adult neurogenesis in the human brain is improbable based on a balanced evaluation of the evidence and limitations of the methodologies used to study it. |
| The paper discusses the debate surrounding the existence and persistence of adult human neurogenesis (AHN). It mentions that the existence of AHN in humans has been widely debated in academia, but does not provide a clear answer to the question. | |
7 Citations | Yes, the paper confirms that adult human neurogenesis does occur, but the location and intensity of neurogenesis in the human brain are still under investigation. |
18 Citations | The paper strongly indicates that humans lack significant adult neurogenesis, suggesting that adult neurogenesis is basically extinct in humans. |
