We examined the relationship between contingent negative variation (CNV) amplitude and digastric muscle activity in jaw-opening motor task. Subjects were instructed to open their jaws in response to a sound stimulus following a visual warning stimulus. Electroencephalograms were averaged by using the visual stimulus pulse as a trigger. Bilateral CNVs were clearly recorded at several cortical locations, with a tendency for larger amplitudes at temporal placements.
我们研究了在张口运动任务中，关联性负变（CNV）波幅与二腹肌活动之间的关系。受试者被要求在视觉警告刺激后，根据声音刺激张开嘴巴。脑电图以视觉刺激脉冲为触发信号进行平均。在几个皮质部位清晰记录到双侧CNV，颞部记录点的波幅有更大的趋势。
