New Neurons Grow in Adult Brains
... The longstanding belief that the adult brain does not produce new neurons is being challenged by current research. Adults may indeed be able to generate new neurons, in a process called neurogenesis, throughout life and at the rate of thousands per day. These findings could radically alter the way s ...
