为了研究清醒和睡眠期间睡眠稳态标志物之间的关系，在40小时的清醒发作期间，以及在基线和恢复睡眠期间，间歇性地记录了8名年轻男性的脑电图。在长时间清醒的过程中，脑电图在5-8 Hz波段（θ波活动）的频谱功率增加。在非快速眼动睡眠中，0.75-4.5 Hz频段（慢波活动）的功率在恢复夜间相对于基线增强。个体记录的比较揭示了清醒时θ波活动的上升率与第一次非快速眼动睡眠期慢波活动的增加之间的正相关性。基于27个推导的地形分析表明，这两种影响都是最大的额叶areas.From这些结果，我们认为，θ波活动在清醒和睡眠中的慢波活动是一个共同的稳态睡眠过程的标志。(C)2000 IBRO。由爱思唯尔科技有限公司出版。保留所有权利。
To investigate the relationship between markers of sleep homeostasis during waking and sleep, the electroencephalogram of eight young males was recorded intermittently during a 40-h waking episode, as well as during baseline and recovery sleep. In the course of extended waking, spectral power of the electroencephalogram in the 5-8 Hz band (theta activity) increased. In nonrapid eye movement sleep, power in the 0.75-4.5 Hz band (slow-wave activity) was enhanced in the recovery night relative to baseline. Comparison of individual records revealed a positive correlation between the rise rate of theta activity during waking and the increase in slow-wave activity in the first non-rapid eye movement sleep episode. A topographic analysis based on 27 derivations showed that both effects were largest in frontal areas.From these results, we suggest that theta activity in waking and slow-wave activity in sleep are markers of a common homeostatic sleep process.
