How Might New Neurons Buffer Against Stress?

Over the past decade or so, evidence has emerged suggesting that the birth of new neurons in the adult brain’s memory hub, or hippocampus, may play a key role the action of antidepressants, resilience to stress, the benefits of exercise and enriched environments and preventing memory loss. But understanding how it might work has remained elusive.

Heather Cameron,Ph.D., chief of the NIMH intramural Unit on Neuroplasticity, discussed findings of ongoing studies on the function of adult neurogenesis in the hippocampus at a research symposium held in March, in conjunction with the formal dedication of the Porter Neuroscience Research Center on the NIH campus in Bethesda, MD, where her lab is located.
