According to new research by neuroscientist Richard Haier, Tetris makes your brain more efficient, as it helps develop some parts of it. In fact, according to Haier, any "challenging visuospatial task" will affect it.

This is the second part of the research. The previous one—from 1992—showed how some brain parts used less glucose as the subjects get more experienced with the game. This new study—which has been paid by the marketing company for Tetris, but peer-reviewed. and published by the journal BMC Research Notes—uses new, more precise imaging techniques to check for brain changes. The target population was adolescent girls, during a three month period. According to Haier, adolescent girls' brains are still developing. Obviously, boys' brains stop functioning properly around age ten.

The study found that the parts in blue where more efficient, while the ones in red got thicker, and stronger, resulting in a more agile, powerful game. [Discover via Neatorama]
