A series of six programmes on our present knowledge of the brain and its activities
2: Perception by PROFESSOR RICHARD GREGORY University of Edinburgh
We do not see the outside world as a camera sees it. As a result of previous experience, our brain adds to the incoming sensory data, so our perception of the external world is far richer than the sense data indicate. What seems to happen is the brain continually forms a model which it compares with the external world. As the external world changes, the sensory data flow in to modify the enriched ' brain model.'
