Alpha rythms in the brain related with time information processing

我们的目的是通过开发一种将大脑活动同步到特定频率的方法来测试“阿尔法节律假说”，即10 Hz阿尔法节律是大脑中时间信息处理的基本模式。在一些参与者中，我们发现，在时间顺序判断的两个连续的刺激的正确反应率取决于相位的交流电流应用transranially与α波段频率。在没有电流应用的对照实验中，我们还发现时间顺序判断取决于两个半球之间的相位差。

We aimed to test an “alpha rhythm hypothesis” that the 10-Hz alpha rhythm is the basic mode for temporal information processing in the brain, by developing a method to synchronize brain activity to a specific frequency. In some participants, we found that the correct response rate in the temporal order judgment of two successive stimuli depended on the phase of alternate currents applied transcranially with an alpha band frequency. In a control experiment without current application, we found in addition that the temporal order judgment depended on the phase difference between the two hemispheres.
