EEG activity was recorded from the right and left central, temporal, parietal and occipital derivations in 10 volunteers under the following conditions: at night before going to sleep, at night before sleep deprivation, in the morning after waking, in the morning after sleep deprivation and in the morning 48 h after recovery. Interhemispheric correlation and relative power were calculated for EEG samples of 20.48 sec. In the morning after normal sleep interhemispheric correlations were higher in all derivations in comparison to presleep values, while in the morning after sleep deprivation, interhemispheric correlations were lower or similar to predeprivation values in all derivations except the temporal cortex. The relative power of beta was significantly lower after normal sleep and higher after sleep loss, while the relative power of low frequencies was higher in the morning after sleep and lower in the morning after deprivation.
在以下条件下，记录了10名志愿者左右中央、颞叶、顶叶和枕叶导联的脑电图活动：睡前夜间、睡眠剥夺前夜间、醒来后早晨、睡眠剥夺后早晨以及恢复后48小时早晨。计算了20.48秒脑电图样本的半球间相关性和相对功率。正常睡眠后早晨，与睡眠前相比，所有导联的半球间相关性均更高；而在睡眠剥夺后早晨，除颞叶皮质外，所有导联的半球间相关性均低于或类似于剥夺前的值。正常睡眠后β波的相对功率显著降低，睡眠缺失后则升高，而低频的相对功率在睡眠后早晨较高，在剥夺后早晨较低。
