Neurogenesis indeed occurs in the human adult brain, according to a new paper in this week's Science. The findings provide new evidence for the long-controversial theory, and suggest that neurogenesis occurs in the olfactory bulb and follows the same pattern as in other mammalian brains.The new paper "disproves the dogma that the human brain doesn't have similar pathways of neurogenesis to that found in other mammalian brains," author Richard L.M. Faull of the University of Auckland said in an Email. "The data are very nice and very clear, just what we'd expect based on rodent work," agreed Heather Cameron, of the National Institute of Mental Health in Bethesda, MD, who is not connected to the study.Many vertebrates create new central nervous system neurons at all stages of life. This talent is linked to the ability to regenerate after CNS injury, so is most common in fish and amphibians....
