Scottish scientists said that they've found the human brain predicts the consequences of eye movement even before the eyes take in a new scene, UPI reported. The researchers, led by Amelia Hunt of the University of Aberdeen, asked subjects to shift their eyes to a clock with a fast-moving hand and report the time on the clock when their eyes landed on it. The scientists found the average reported time was 39 milliseconds before the actual time. "We've revealed a moment in time when things are not perceived as they actually are," Hunt said. "These findings serve as a reminder that every aspect of our experience is constructed by our brains." She said the report suggests the prediction is a result of remapping, where neurons involved in visual perception become active or dormant to help the brain maintain a stable visual environment despite the constant shift of images on the retina. Hunt said the research might lead to more investigation of the brain's ability to predict and its role in perception, as well as the link between brain activity and actual experience. The study is reported in the Journal of Vision.
