RELATIONSHIP BETWEEN

THE EYES AND THE BRAIN

The image below is an example of what is commonly known as an optical illusion. It highlights how our brain processes what our eyes see. The brain does this by making a prediction about what our eyes are seeing. The relationship between the eyes and the brain ( visual processing system)  is extremely complex, however we are offered some insight into visual perceptions and it's limitations. In this picture, our eyes actually see the object, but the brain is seeing something else.
