Aerobic Exercise a Smart Choice
We know that exercise is good for us and that it can change brain structure and thought patterns...but researchers are now learning that it's aerobic exercise specifically that really makes a difference. Henriette van
Praag, an investigator in the Laboratory of Neurosciences at the
National Institute on Aging, says it's all about growth factors that get carried from the
periphery of the body into the brain, starting a molecular cascade which creates new neurons and connections. This can only happen with the dramatic changes in blood flow that occur with aerobic activities such as running, cycling or swimming.
