The Trickiness of your Own Eyeballs

Do you try these sort of illusions when you find them? I really like how our own senses can trick us in so many unique and weird ways. If you have other links like this add them to comments. Share and share alike.

Look at the picture below, and stare at the little white point on the nose of the woman for about 15 seconds. Then look at the white square. Did you just see a woman appear? This is what we call the opponent process. It’s a combination of different wavelengths that makes us perceive color. The wavelengths are processed in our brain. Special neurons that are present in the lateral geniculate nucleus react to different pairs of colors. Green is paired with red, yellow is paired with blue and white is paired with black. The picture of the girl represents only one color of a pair. So in the afterimage you’ll see the opposite paired color.
