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.
人类的日常行为依赖于我们根据即时信息预测结果的能力。长期以来,神经相位同步被认为是一种“预测”能够对传入感觉事件的处理产生影响的机制。我们使用脑磁图(MEG)研究了参与视觉目标处理的脑区网络中相位同步调制与目标出现的可预测性之间的关系。我们的结果显示,随着目标出现概率的增加,相位同步调制显著增强。这些观察结果与以下假设一致,即长期相位同步在人类有效运用预测启发式方法的能力中起着关键的功能作用。
