Brain Story

The Mind's Eye
Season 1  |  Episode 3  |  The History Channel  |  August 17, 2009

The illusion of vision. It feels as though we open our eyes and just see what's out there, but the more we learn about the brain's visual system, the further it seems this is from the truth. Patients, who can't see movement or recognise faces, reveal the tricks and short cuts the brain uses to construct an illusion of reality. Is the brain making up so much of what we think we're seeing that vision is really just dreaming with your eyes open?
