Anticipatory control of long‐range phase synchronization

Everyday human behaviour relies on our ability to predict outcomes on the basis of moment by moment information. Long‐range neural phase synchronization has been hypothesized as a mechanism by which ‘predictions’ can exert an effect on the processing of incoming sensory events. Using magnetoencephalography (MEG) we have studied the relationship between the modulation of phase synchronization in a cerebral network of areas involved in visual target processing and the predictability of target occurrence. Our results reveal a striking increase in the modulation of phase synchronization associated with an increased probability of target occurrence. These observations are consistent with the hypothesis that long‐range phase synchronization plays a critical functional role in humans' ability to effectively employ predictive heuristics.
