“Just look around you now. The eyes send a hundred billion signals to the brain every second. But that’s only part of the story. When you “see” something, only about 10 percent of the information comes from the optic nerve. Other parts of your brain have to deconstruct the signals—recognize faces, interpret movements, identify danger. In other words, the biggest part of seeing isn’t receiving visual images; it’s making sense of them. Bryson, Bill. The Body (p. 54). Knopf Doubleday Publishing Group. Kindle Edition. ”
