在家中记录了年龄 54-72 岁的 8 名健康男性和 8 名女性的睡眠脑电图。对脑电图进行视觉评分，并使用 FFT 方法通过频谱分析进行分析。除了女性处于 3+4 阶段的比例较高之外，睡眠参数没有显着差异。 δ波段脑电图的频谱功率分为两个频率：0.5-2 Hz和2-4 Hz。女性整夜的δ波段光谱功率总量明显更大。在女性中观察到δ波段功率的周期性波动以及非快速眼动-快速眼动周期。
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.
