Nuclear testing from the 1960s helps scientist determine whether adult brains generate new neurons

The birth of new neurons in the adult brain sharpens memory in rodents, but whether the same holds true for humans has long been debated. A new study reveals that a significant number of new neurons in the hippocampus -- a brain region crucial for memory and learning -- are generated in adult humans.
