In recent years, the idea that neurogenesis – the production of new neurons – occurs in specific regions of the adult brain has become widely accepted, and much discussed. Disruptions to neurogenesis have been proposed to play a role in stress, depression, and other disorders.
However, Dennis et al. say that ne
