Analysis of wake-sleep structure.

W, wakefulness; NREMS, non-rapid-eye-movement sleep; REMS, rapid-eye-movement sleep; eps/24 h, number of episodes in 24 hours; D, episode duration; ACT, motor activity (arbitrary units, au); latency, time elapsed between onset of REMS episodes and termination of previous W episodes. Data are mean ± SEM in orexin-ataxin3 transgenic mice (TG, n = 11) and wild-type controls (WT, n = 12) recorded at ambient temperatures (Ta) of 20°C and 30°C. a, b, and axb, P<0.05 for main effects of Ta and mouse group and for interaction effect, respectively (ANOVA).
*and †,P<0.05 vs. WT and vs. 30°C Ta, respectively (t-test).

W代表觉醒（Wakefulness）；NREMS代表非快速眼动睡眠（non-rapid-eye-movement sleep）；REMS代表快速眼动睡眠（rapid-eye-movement sleep）；eps/24 h指每24小时的发作次数；D指发作时长；ACT指运动活动（单位为任意单位，au）；latency指快速眼动睡眠发作起始与前一次觉醒发作终止之间的间隔时长。实验对象为食欲素-共济失调蛋白3转基因小鼠（TG，n=11）与野生型对照小鼠（WT，n=12），分别在环境温度（Ta）20℃与30℃条件下进行记录，所有数据以均值±标准误（SEM）呈现。统计显著性标注规则如下：a、b与a×b分别代表经单因素方差分析（ANOVA）检验后，环境温度、小鼠组别以及二者交互效应的P<0.05；*与†分别代表经t检验后，与野生型对照（WT）组以及30℃环境温度组存在显著差异（P<0.05）。
