Neurogenesis in the Adult Olfactory Bulb

Active neurogenesis from neural progenitors continues throughout life in discrete regions of the central nervous system of most mammals. However, human adult neurogenesis is still a contentious issue. Signs of adult neurogenesis have been reported in the hippocampus, but a second neurogenic niche described in rodents has not been found in recent human studies. Curtis et al. have just published a paper in Science not only describing this missing rostral migratory stream in great detail but also showing that it is organized around a tubular extension of the lateral ventricle that reaches into the olfactory bulb.
