One way exercise might boost memory

It’s been shown for a while that exercise leads to increased production of nerve cells, and that exercise improves brain function. Tara Parker Pope writes about a study in which people were given memory tests while in an imaging machine, and the researchers found that those better at remembering had more activity in the dentate gyrus. The dentate gyrus is one of the areas in which exercise promotes new brain cell growth, so this area may be at least of the links between brain power and muscle power.
