Turns out all that Tetris playing you did yesterday as a kid does some good after all: a new study published at Mind Research Network suggests that "practicing Tetris" can improve the brain's efficiency and build up a thicker cortex in other areas of the tabula rasa.

The study was carried out to prove the brain's ability to change with stimulation, and that "a challenging visuospatial task has an impact on the structure of the cortex."

Sure, Tetris is incredibly old, but it's definitely one way to get your parents to believe that gaming is good for you.
