Learning To See Upside-Down

In the late 1800s, a scientist named George Stratton claimed that his brain adjusted so well to seeing upside-down that the world actually appeared right-side up again. Although researchers have not been able to emulate these results, they have learned that the brain can adapt to an upside-down view rather quickly. After a week or so of wearing inversion glasses, most people are able to ride a bike, catch a ball, and perform other tasks that are initially almost impossible.
