Now you see it: Best visual illusions of 2009
Every visual illusion - from the way that simple lines drawn on paper seem to form a cube, to the logic-defying labyrinths of M. C. Escher - works exactly the same way: they expose discrepancies between physical reality and our perception of that reality.
That makes visual illusions appealing objects of study for neuroscientists: they offer clues to how our brains handle the information we receive about the outside world, in particular how we process visual images.
