本文研究了社会应激对大鼠睡眠脑电图的影响。通过将动物引入具有攻击性的雄性同种动物的笼子中1小时，使动物遭受单一的社会失败。动物对社会冲突的反应是在非快速眼动睡眠（NREM）期间EEG慢波活动（SWA）急剧增加。由于SWA已被确定为睡眠强度的指标，因此结果表明，急性压力源可能会加速睡眠债的积累。因此，睡眠强度不仅取决于先前清醒的持续时间，还取决于清醒体验的性质。社交失败后SWA的强烈增加表明睡眠可能起到抵消清醒时施加在神经系统上的精神负荷的作用。(C)1997 Elsevier Science爱尔兰有限公司
We studied the effect of social stress on sleep electroencephalogram (EEG) in rats. Animals were subjected to a single social defeat by introducing them in the cage of an aggressive male conspecific for 1 h. The animals responded to the social conflict by a sharp increase in EEG slow-wave activity (SWA) during non-rapid eye movement sleep (NREM) afterwards. Since SWA has been identified as an indicator of sleep intensity, the results suggest that acute stressors may accelerate the build up of sleep debt. Sleep intensity may, thus, not only depend on the duration of prior wakefulness but also on the nature of the waking experience. The strong increase in SWA after social defeat indicates that sleep may function to offset the mental loads imposed on the nervous system during wakefulness. (C) 1997 Elsevier Science Ireland Ltd.
