Default Prime's Lucas Stephens says, "Do you remember Brain Age? Wouldn’t it be funny had you played Brain Age but forgotten all about it? The DS was treated with two Brain Age games, designed by Japanese neuroscientist Dr. Ryuta Kawashima. Using the DS’s unique hardware features such as the microphone and touch screen, those two pieces of software presented the gamer with different training exercises to enhance a multitude of different brain functions. It’s been quite some time, almost six years, since the second Brain Age, and now Dr. Ryuta Kawashima returns with a new Brain Age, this time for the 3DS."
