Go Play Tetris!

I came across an interesting article in the NY Times online I wanted to share. It showed a positive change in peoples reactions having viewed traumatic events after playing Tetris. They became less reactive. I am interested in finding out if this is the same part of the brain that is affected in EMDR, helping to neutralize the event.
