An experiment is described which compared visual evoked potential (VEP) amplitudes and latencies in normal subjects and migraine patients. Several VEP abnormalities were found: at vertex and to a lesser extent at temporal sites, P100-N120 amplitudes were larger in patients; at vertex and temporal sites N120 amplitudes were larger in patients; at temporal sites patents had larger N120-P200 amplitudes but smaller P100 amplitudes. Peak latencies of the VEP were also found to be abnormal in patients. At vertex, patients had delayed N120 peak latencies while at temporal sites delays were found in the P200 latencies. Patients were subdivided according to side of headache. Right-sided headache patients showed larger temporal P100 amplitudes and larger left temporal P100-N120 amplitudes than bilateral headache patients.
本文描述了一项实验，该实验比较了正常受试者和偏头痛患者的视觉诱发电位（VEP）振幅和潜伏期。发现了一些VEP异常情况：在头顶以及在较小程度上在颞部位置，患者的P100 - N120振幅更大；在头顶和颞部位置，患者的N120振幅更大；在颞部位置，患者的N120 - P200振幅更大但P100振幅更小。还发现患者的VEP峰值潜伏期也异常。在头顶，患者的N120峰值潜伏期延迟，而在颞部位置，P200潜伏期延迟。患者根据头痛侧进行了细分。右侧头痛患者比双侧头痛患者表现出更大的颞部P100振幅和更大的左侧颞部P100 - N120振幅。
