This article is a critical review of standard electroencephalography (EEG), brain mapping, evoked potential, and electromyography (EMG) studies carried out in various forms of migraine during and between attacks. With the exception of contingent negative variation, the exteroceptive silent period of the temporalis muscle, and possibly fast activity in response to visual stimuli, which are useful for the differential diagnosis of functional headache, the main value of electrophysiologic studies is to provide insight into the pathophysiology of the disease. Results of the different methods consistently indicate that the brain of migraine patients is characterized by hypersensitivity to some forms of stimuli between attacks and by, often focal, hypoactivity during attacks.
本文是对在偏头痛发作期间及发作间期以各种形式进行的标准脑电图（EEG）、脑图谱、诱发电位和肌电图（EMG）研究的批判性综述。除了关联性负变、颞肌的外感受性静息期以及可能对视觉刺激产生的快速活动（这些对功能性头痛的鉴别诊断有用）外，电生理研究的主要价值在于深入了解该疾病的病理生理学。不同方法的结果一致表明，偏头痛患者的大脑在发作间期对某些形式的刺激表现出超敏反应，而在发作期间通常表现为局灶性活动减退。
