Numerous studies of perceptual decision-making have shown that lower prestimulus alpha power leads to a higher hit rate in visual detection, which is believed to correlate with the top-down control. However, whether frontal-occipital phase synchronization underlying the top-down control could impact the occipital alpha power that directly affects the perceptual performance remains unclear. In this study, we used analyses of the general linear mixed model (GLMM) and event-related potentials (ERPs) to show that the prestimulus alpha power over the occipital area directly affected visual perception. Using both the univariate and multivariate methods, we found that low-frequency (4-30 Hz) frontal-occipital phase synchronization predicted the prestimulus alpha power over the occipital area. Overall, our results suggested that frontal-occipital phase synchronization could predict occipital alpha power that directly affects perceptual decision-making.

众多关于知觉决策的研究表明，刺激前较低的阿尔法波功率会导致视觉检测中的较高命中率，这被认为与自上而下的控制相关。然而，自上而下控制背后的额枕相位同步是否会影响直接影响知觉表现的枕叶阿尔法波功率仍不清楚。在本研究中，我们使用一般线性混合模型（GLMM）分析和事件相关电位（ERP）表明，枕叶区域的刺激前阿尔法波功率直接影响视觉感知。使用单变量和多变量方法，我们发现低频（4 - 30赫兹）额枕相位同步可预测枕叶区域的刺激前阿尔法波功率。总体而言，我们的结果表明额枕相位同步可以预测直接影响知觉决策的枕叶阿尔法波功率。
