Give your gray matter the workout that it needs! Brain Age: Train Your Brain in Minutes a Day is inspired by research conducted by Professor Ryuta Kawashima, a prominent Japanese neuroscientist. His theories revolve around keeping your brain "young" by performing certain mental activities quickly. The title is a series of mini-games designed to give your brain a workout. Activities include simple math problems, counting people going in and out of a house, drawing pictures on the Touch Screenm and reading classic literature out loud. When you start a new game, you will take a series of tests and get a score that shows your "DS Brain Age". As you use the software, your in-game Brain Age will drop. You can keep up to four files on one Game Card - play against family and friends! ESRB Rating: Everyone
