Sleep EEG of eight healthy males and eight females aged 54-72 years were recorded at their homes. The electroencephalograms were visually scored and analyzed by spectral analysis using the FFT method. There were no significant differences in sleep parameters except for a higher percentage of stage 3+4 in females. The spectral power of the delta band EEG was classified into two frequencies: 0.5-2 Hz and 2-4 Hz. The total amount of the delta band spectral power through the night was significantly larger in females. Periodic fluctuation of delta band power was observed in females along with non-rapid eye movement-rapid eye movement cycles.
对8名年龄在54至72岁之间的健康男性和8名健康女性进行了在家中的睡眠脑电图记录。脑电图由专业人员进行视觉评分，并使用快速傅里叶变换（FFT）方法进行频谱分析。除了女性的3+4期睡眠比例较高外，睡眠参数没有显著差异。δ波脑电图的频谱功率被分为两个频率：0.5-2赫兹和2-4赫兹。女性夜间δ波频谱功率的总量明显更大。在女性中观察到δ波功率随非快速眼动-快速眼动周期出现周期性波动。
