How your brain remembers the future - life - 02 April 2010 - New Scientist: "Predictable sights trigger less brain activity than unfamiliar stimuli, bolstering the view that the brain is not merely reactive, but generates predictions based on the recent past. 'The brain expects to see things and really just wants to confirm it now and again,' says Lars Muckli at the University of Glasgow, UK."
This "Bayesian" brain theory says our brain builds a model of the world, and uses that to predict what should happen next,. It only shifts into high gear when stimuli don't match predictions.
