We investigate phase synchronization in EEG recordings from migraine patients. We use the analytic signal technique, based on the Hilbert transform, and find that migraine brains are characterized by enhanced alpha band phase synchronization in the presence of visual stimuli. Our findings show that migraine patients have an overactive regulatory mechanism that renders them more sensitive to external stimuli.
我们研究了偏头痛患者脑电图记录中的相位同步情况。我们使用基于希尔伯特变换的解析信号技术，发现偏头痛患者的大脑在视觉刺激存在时表现为增强的阿尔法波段相位同步。我们的研究结果表明，偏头痛患者具有过度活跃的调节机制，这使他们对外界刺激更加敏感。
