London, Aug 26 - The human brain can perceive the outcome of eye movement split seconds before they take in a new scene, says a new study.
Researchers asked participants in the study to shift their eyes to a clock with a fast-moving hand and report the time when their eyes landed on the clock. The average reported time was 39 milliseconds before the actual time.
As a control task, the clock moved instead of the eyes, and the reported arrival time averaged 27 milliseconds after the actual time.
'We've revealed a moment in time when things are not perceived as they actually are,' said lead researcher Amelia Hunt from the University of Aberdeen's School of Psychology.
'These findings serve as a reminder that every aspect of our experience is constructed by our brains.'
The report suggests that 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.
