Catch your thoughts

I watched an episode of The Simpsons last night, where my favorite character Lisa got caught thinking. In her opinion, it was morally wrong to dissect an animal. After telling her teacher this, the "Independent thought-alarm" was pushed and a series of brainwashing followed. A group of researchers at the University of Illinois catches and monitors thoughts too but in a complete other way and for a completely different reason than the Springfielders do. Here's a snapshot of the exact moment when the brain understands the received visual information (from the eyes), and here's a short video clip of the same event.
