本研究探讨了急性足电击应激（FS）对豚鼠睡眠时咀嚼肌节律性活动（RMMA）的影响。动物准备进行慢性记录，从脑电图，眼电图和肌电图的颈部和咬肌。连续两天记录信号6小时：第一天无应激条件（非FS条件），第二天急性FS条件（FS条件）。对睡眠/觉醒状态和RMMA进行视觉评分。睡眠变量和频率的RMMA发生在非快速眼动（NREM）睡眠期间进行了比较，在6小时内的两种条件。与非FS条件相比，FS条件下急性FS后2 h内总睡眠和NREM睡眠量显著减少。同样，与非FS条件相比，FS条件下急性FS后2小时内RMMA的频率显著增加。在FS条件下，FS后2-6小时内，睡眠变量和RMMA的频率与非FS条件下无FS的睡眠变量和RMMA的频率没有差异。这些结果表明，急性实验应激可引起实验动物睡眠-觉醒状态的短暂改变和RMMA的发生。
This study investigated the effects of acute footshock stress (FS) on the occurrence of rhythmic masticatory muscle activity (RMMA) during sleep in guinea pigs. Animals were prepared for chronic recordings from electroencephalogram, electrooculogram and electromyograms of neck and masseter muscles. The signals were recorded for six hours on the two successive days: the first day with stress-free condition (non-FS condition) and the second day with acute FS (FS condition). Sleep/wake states and RMMA were scored visually. Sleep variables and the frequency of RMMA occurring during non-rapid eye movement (NREM) sleep were compared during 6-h periods between the two conditions. Compared to non-FS condition, the amount of total sleep and NREM sleep significantly reduced during 2 h following the acute FS in the FS condition. Similarly, the frequency of RMMA significantly increased during 2 h following the acute FS for the FS condition compared to non-FS condition. During 2–6 h after FS in the FS condition, sleep variables and the frequency of RMMA did not differ from those without FS in the non-FS condition. These results suggest that acute experimental stress can induce transient changes in sleep–wake states and the occurrence of RMMA in experimental animals.
