Brain Hypotheses

Did you know that the brain’s main job, much like that of a scientist, is to generate hypotheses about what is going on in the outside world? Apparently the brain does not just sit and wait for visual signals to arrive. Instead, it actively tries to predict these signals. When it is right it is rewarded by being able to respond more efficiently. If it is wrong, it tries to figure out how it was wrong and to come up with better predictions.
