Tetris and the mind

I can remember reading about a study that used a PET scan to measure brain activity and compared the levels of glucose use when people started playing tetris, to when they became an expert. Experts, used less glucose, and so perhaps less of their brain when they were functioning at a higher level.

To me this is another idea that flies in the face of the suspicious 10% of the brain idea.

Here's an article (not the one I orginally read, but just as good) about the study

Tell me in your blog if you've had a video game induced hypnagogic hallucination (those crazy half-dreams you have before going to sleep).
