Source of new neurons for the hippocampus

Written by Jenny Straiton

A single population of neural stem cells contributes to the continuous production of neurons in the adult hippocampus. Though it was once believed that no neurogenesis occurred in the central nervous system post birth, in the past few years neuroscientists have demonstrated the regenerative ability of the olfactory system and the hippocampus. In a study recently published in Cell, researchers from the University of Pennsylvania (PA, USA) have found the source of such a capability and demonstrated that, in murine models, a single population of neural stem cells are responsible for the development of new neurons in the hippocampus.
