According to new research done at Duke University, neurons in the brain predict and edit what you see before you see it. And the brain's visual circuits perform "error correction" on the fly. The fMRI study results have led to a new picture of human vision (labeled predictive coding) and challenge the currently held model of sight. The study could change the way in which neuroscientists study the brain. It seems that vision is more complex than scientists previously believed. Apparently, the current picture of human vision (called feature detection) is incomplete. The new data show the brain predicts what it will see and edits those predictions in a top-down mechanism.
