Can the brain grow neurons later in life? For now, the answer is ‘maybe’

In the past month, two studies came to very different conclusions when examining if the human brain is capable of growing new neurons later in life. The first, published March 7 in Nature, found no evidence of neurogenesis in individuals older than 13 years old. But another study, released April 5 in Cell Stem Cell, claimed to find neuron generation in all the brains examined.
