Face processing to see the future

Most visual processing is studied with single images or snap shots, yet the world we experience changes continuously and predictably. I will describe how brain cells sensitive to the face and body encode sequences of images that record natural actions. During such sequences, we find short-term changes in sensitivity make cell responses 'predictive'. The most active cells are those encoding 'future' images that are likely to occur given the past sequence. An implication is that the brain is not coding current sensory inputs but rather is predicting what is going to happen (100ms ahead). I conclude that we experience the future that is likely and not the present reality.
