Stare at a spinning ceiling fan for a while, and it will eventually -- just for a moment -- appear to spin in the opposite direction. Although this seems like the kind of visual hiccup that might be observed and just as quickly forgotten, the laboratory of Dr. David Eagleman recognizes glitches of visual perception as crucial for understanding the normal function of the brain.
