Scientists have found evidence of new brain cells sprouting in adults - a process that many thought only occurred in children

Scientists say they have very strong evidence that the adult human brain is capable of making new neurons, a point of ongoing controversy in neuroscience.

Scientists in Sweden led the study, published Thursday in Science. They found abundant signs of neural stem cells growing in the hippocampus of adult brains. The findings reveal more about the human brain as we get older, the researchers say, and also hint at potential new ways to treat neurological disorders.
