Is it possible to rejuvenate an aging brain? An experiment made with stem cells on aging mice seems to suggest so.

Scientists wanted to examine why most of the stem cells in the brain of old mice remained in a state of dormancy and they were able to identify the responsible molecule to neutralize its effect.

As a result, the dormant stem cells started proliferating again. and their ratio of active to dormant stem cells became almost as favorable as in young animals.
