A new method, named the 'alpha wave modulated light' (AML) stimulation, has been used for controlling the frequency of sine wave modulated light by the subject's on-going alpha rhythm. The EEG was recorded from O1 and O2. With the AML stimulation using either the left occipital alpha rhythm or the right, two phase differences of O degrees and 180 degrees were created between AML and the alpha rhythmn. The peak frequency and power of occipital alpha in both hemispheres and the coherence and phase between the left and right occipital EEG were obtaned for 7 subjects. The alpha power was larger at a 180 degrees phase shift than at a 0 degrees phase shift with ipsilateral AML stimulation. The ipsilateral increase in the alpha power was greater than the contralateral at a 180 degrees phase shift. Larger coherence value and right phase lead were observed at 180 degrees phase shift by use of the right alpha rhythm. The possible mechanisms of influences of AML stimulation on the alpha activity were discussed.
一种名为“阿尔法波调制光”（AML）刺激的新方法已被用于通过受试者持续的阿尔法节律来控制正弦波调制光的频率。脑电图记录自O1和O2。使用左侧枕叶阿尔法节律或右侧枕叶阿尔法节律进行AML刺激时，在AML与阿尔法节律之间产生了0度和180度的两个相位差。对7名受试者获取了两半球枕叶阿尔法的峰值频率和功率以及左右枕叶脑电图之间的相干性和相位。在同侧AML刺激下，180度相移时的阿尔法功率大于0度相移时的。在180度相移时，同侧阿尔法功率的增加大于对侧。通过使用右侧阿尔法节律，在180度相移时观察到更大的相干值和右侧相位超前。讨论了AML刺激对阿尔法活动影响的可能机制。
