The present study was performed in order to determine whether spontaneous K-complex are induced by sensory stimuli. Electroencephalogram (EEG) segments in stage 2 sleep containing an evoked K-complex or spontaneous K-complex were separately averaged with respect to the peak of N300, one of the main components constituting the K-complex. Small negative and positive components were found immediately before the main components of spontaneous K-complex in averaged EEG. These two components were judged to correspond to N100 and P200 induced by the sound stimulus. The present findings suggest that the spontaneous K-complex is not a spontaneous phenomenon but that it is induced by sensory stimuli.
本研究旨在确定感觉刺激是否会诱发自发性K复合波。对于包含诱发K复合波或自发性K复合波的第2阶段睡眠中的脑电图（EEG）片段，分别以构成K复合波的主要成分之一N300的峰值为基准进行平均。在平均脑电图中，在自发性K复合波的主要成分之前立即发现了小的负性和正性成分。这两个成分被判断对应于声音刺激诱发的N100和P200。目前的研究结果表明，自发性K复合波不是一种自发现象，而是由感觉刺激诱发的。
