It was at his Columbia University lab, in 2007, where they witnessed telltale signs of neurogenesis for the first time in live humans. “Five years ago people said, OK, it might happen, but is it really meaningful? Now there isn’t a week that goes by where there’s not another study that shows neurogenesis has some kind of effect on the brain.”
What really feeds those baby brain cells? Hitting the gym.
A 3 month exercise regimen increased bloodflow to the part of your brain focused on memory and learning by 30%.
In his study, Small put a group of volunteers on a three-month exercise regimen and then took pictures of their brains. By manipulating a standard MRI machine’s processing— essentially zooming in and cocking the shutter open— he captured images of the newly formed capillaries required for nascent neurons to survive. What he saw was that the capillary volume in the memory area of the hippocampus increased by 30 percent, a truly remarkable change.
