Study Questions Whether Adults Can Really Make New Neurons
March 8, 2018
(Science) – Over the past 20 years, evidence that adult humans can produce hundreds of new neurons per day has fueled hope that ramping up cell birth could be therapeutic. Boosting neurogenesis, researchers speculate, might prevent or treat depression, Alzheimer’s disease, and other brain disorders. But a controversial study in Nature this week threatens to dash such hopes by suggesting that the production of neurons declines sharply after early development and grinds to a halt by adulthood.
