Four all-night polysomnograms of a 39-year-old male patient with non-24 h sleep-wake syndrome were recorded. We analysed electroencephalograms (EEG) with the power spectrum method and the wave pattern recognition analysis of Fujimori. The EEG of the rest waking condition showed normal patterns. High-voltage diffuse alpha band waves were observed in sleep stages 2, 3 and 4. The integrated area of the alpha band waves in the analysis epochs showed a strong positive correlation to the delta band components in the power spectrum of the same epoch during sleep (correlation coefficients r = 0.762-0.815). Alpha band waves during sleep were clearly different from the alpha waves in the rest waking condition, with respect to slower peak frequency and the frontal dominant voltage distribution.
记录了一名患有非24小时睡眠-清醒综合征的39岁男性患者的4次整夜多导睡眠图。我们采用功率谱法和藤森波形识别分析法对脑电图（EEG）进行了分析。清醒休息状态下的脑电图显示正常模式。在睡眠2期、3期和4期观察到高电压弥漫性α波段波。分析时段内α波段波的积分面积与睡眠期间同一时段功率谱中的δ波段成分呈强正相关（相关系数r = 0.762 - 0.815）。睡眠期间的α波段波在峰值频率较慢和额叶优势电压分布方面与清醒休息状态下的α波明显不同。
