Two things to note from the article:
1) It seems to mostly be focused on neurogenesis in the hippocampus, not necessarily elsewhere in the brain.
2) It seems the key item these researchers hit on to invalidate the previous study was the method of preservation for brain tissue in deceased individuals, not study of tissue in living humans. I think new studies in that latter area in the future will put the matter to rest.
- superkuh 8y agoNeurogenesis has always been about the hippocampus in humans. It's been lightly suggested it might happen in the olfactory bulb (as in other animals) but not very seriously. When neuroscientists talk about human neurogenesis in adulthood it is always about the hippocampal formation and the dentate gyrus. For an up to date review/link-set of neurogenesis in humans as compared to other mammals check out the summary write-up over at http://blogs.discovermagazine.com/neuroskeptic/2019/01/30/new-look-neurogenesis-humans/ http://blogs.discovermagazine.com/neuroskeptic/2019/01/30/ne... which makes the case that human neurogenesis isn't found in adulthood because of relative lifespan differences.
