Spark!: How exercise will improve the performance of your brain

To take the example of karate, as you perfect certain forms, you can incorporate them into more complicated movements, and before long you have new responses to new situations. The same would hold true for learning tango. The fact that you have to react to another person puts further demands on your attention, judgment, and precision of movement, e

To illustrate, he uses the example of a tiny jellyfish-like animal called a sea squirt: Born with a simple spinal cord and a three hundred–neuron “brain,” the larva motors around in the shallows until it finds a nice patch of coral on which to put down its roots. It has about twelve hours to do so, or it will die. Once safely attached, however, the

Take the cerebellum, which coordinates motor movements and allows us to do everything from returning a tennis serve to resisting the pull of gravity. Starting with evidence that the trunk of nerve cells connecting the cerebellum to the prefrontal cortex are proportionally thicker in humans than in monkeys, it now appears that this motor center also

For an inner-city school to go through such a rapid transformation, and for such a depressed town as Titusville to come alive as it has, is remarkable. McCord’s community rallies around the Stephanies of the world rather than just the football team, and as the schoolchildren grow up, a larger percentage will continue to move and be active. They’ll

Now you know how exercise improves learning on three levels: first, it optimizes your mind-set to improve alertness, attention, and motivation; second, it prepares and encourages nerve cells to bind to one another, which is the cellular basis for logging in new information; and third, it spurs the development of new nerve cells from stem cells in t

“neurogenesis is clearly involved in our interactions with our environment, both emotionally and cognitively,” says neuroscientist Fred Gage, of the Salk Institute in La Jolla, California.

Any motor skill more complicated than walking has to be learned, and thus it challenges the brain. At first you’re awkward and flail a little bit, but then as the circuits linking the cerebellum, basal ganglia, and prefrontal cortex get humming, your movements become more precise.

Learning the asanas of yoga, the positions of ballet, the skills of gymnastics, the elements of figure skating, the contortions of Pilates, the forms of karate—all these practices engage nerve cells throughout the brain. Studies of dancers, for example, show that moving to an irregular rhythm versus a regular one improves brain plasticity. Because

The notion that it might is supported by emerging research showing that physical activity sparks biological changes that encourage brain cells to bind to one another.
