Memory Improves If Neurons Are New

The birth of new neurons (neurogenesis) does not end completely during development but continues throughout all life in two areas of the adult nervous system, i.e. subventricular zone and hippocampus. Recent research has shown that hippocampal neurogenesis is crucial for memory formation. These studies, however, have not yet clarified how the newborn neurons are integrated in the existing circuits and thus contribute to new memories formation and to the maintenance of old ones.
