Neurogenesis is the formation of new neurons from neural stem cells (NSCs). It is an endogenous process that has been observed throughout life into advanced age. NSCs reside in at least two regions of the adult brain: the dentate gyrus of the hippocampus and the subventricular zone, which lines the lateral ventricles. Additional information about neurogenesis, Alzheimer's disease, and drug development can be found in our team’s publications.
