Neurogenesis in the Striatum of the Adult Human Brain

• Neurons are added throughout life in the hippocampus and olfactory bulb in most mammals, although humans represent an exception without detectable olfactory bulb neurogenesis. Nevertheless, neuroblasts are generated in the lateral ventricle wall in humans, the neurogenic niche for olfactory bulb neurons in other mammals. We show that, in humans, new neurons integrate adjacent to this neurogenic niche, in the striatum. The neuronal turnover in the striatum appears restricted to interneurons and we show that postnatally generated striatal neurons are preferentially depleted in Huntington’s disease. This demonstrates a unique pattern of neurogenesis in the adult human brain.
