the brain is one crazy organ, the shit that thing can do really does amaze me. For example, some crazy bastard figured out a way to allow people to see via a camera that attaches to their tongue. Weird huh. I can't wait to see what all we're capable of as we figure out more and more of how our brain works.
Seriously go here, they've got a video that explains it better, plus it a built in hat tip because thats where I found the article.
I wish I had more to add on the subject.
