“Once these findings were established in mice, we were interested in determining how exercise affects the hippocampal cerebral blood volume maps of humans,” … They of course could not dissect the brains of people to see if new neurons grew, but they could use MRI to have a peek. (The experiment) also measured the fitness of each volunteer by measuring oxygen volume before and after the training program. Exercise generated blood flow to the dentate gyrus of the people, and the more fit a person got, the more blood flow the MRI detected, the researchers found.
