"Only one activity is known to trigger the birth of those new neurons: vigorous aerobic exercise."

30 to 40 minutes of sweat-inducing exercise can give both cognitive clarity and allow the brain to create new neurons

It was believed that once a human reached adulthood, the number of neurons they produced stopped: 30 years of research seem to indicate that this many not be the case. The Science of Us section of the New York Times looks at neurogenesis, or how 30 to 40 minutes of sweat-inducing exercise can give both cognitive clarity and allow the brain to create new neurons.

The other fascinating thing here is where these new cells pop up: in the hippocampus, a region of the brain associated with learning and memory. So this could help explain, at least partially, why so many studies have identified a link between aerobic exercise and improvement in memory. “If you are exercising so that you sweat — about 30 to 40 minutes — new brain cells are being born,” added Postal, who herself is a runner. “And it just happens to be in that memory area.”

Other post-run changes have been recorded in the brain’s frontal lobe, with increased activity seen in this region after people adopt a long-term habit of physical activity. This area of the brain — sometimes called the frontal executive network system — is located, obviously enough, at the very front: It’s right behind your forehead. After about 30 to 40 minutes of a vigorous aerobic workout – enough to make you sweat – studies have recorded increased blood flow to this region, which, incidentally, is associated with many of the attributes we associate with “clear thinking”: planning ahead, focus and concentration, goal-setting, time management.
