witKeeping the mind young, strong - Entertainment - The Washington Times, America's Newspaper: "Here's a look at a science-themed game and a Web site to help stimulate the noggin:
Brain Age, from Nintendo for Nintendo DS, rated E: content suitable for ages 13 and older, $19.99. Nintendo's magical hand-held gaming system celebrates the work of Japanese neuroscientist Ryuta Kawashima by engaging owners in a series of hands-on exercises geared to giving their gray matter a rigorous workout.

Users turn their dual-screen DS system sideways to view the presentations as if reading a book. Mr. Kawashima makes an appearance (as a gregarious, disembodied talking head) to explain his theory that just as muscle mass decreases with age, so does brain function, and only by performing certain types of mental activities each day will we keep our minds young and in tiptop shape.

Tuning the prefrontal cortex involves using the DS' microphone and touch screen to perform nine timed activities centered around simple reading and mathematical problem solving.

Once users save some personal data, they measure the current age of their brains using the Stroop Test. A series of colored words is flashed on both screens, and the user must say the color of the words. Speed and proficiency indicate a lower brain age. Users can test their age every day and watch the graphics and statistics for improvements as Mr. Kawashima encourages them. "
