摘要
We investigated sleep-wake (S-W) architecture and sleep regulation in the ferret: a phylogenetically primitive mammal increasingly used in neurobiological studies. Twenty-four hour S-W baseline data were collected in eight adult ferrets. Seven ferrets were then sleep deprived for 6 h at the beginning of the light period. Like other placental mammals, ferrets exhibited the main vigilance states of wakefulness, rapid-eye-movement (REM) sleep and non-REM (NREM) sleep. Interestingly, the amount of REM sleep in the ferret was considerably higher (24.01 ± 1.61% of total recording time) than typically reported in placental mammals. Ferret sleep was homeostatically regulated as sleep deprivation produced a significant increase in NREM EEG delta power during the recovery period. Therefore, ferret sleep in most respects is comparable to sleep in other placental mammals. However, the large amount of REM sleep in this phylogenetically more ancient species suggests that REM sleep may have been present in greater amounts in early stages of mammalian evolution.

我们研究了雪貂中的睡眠 - 觉醒（S-W）结构和睡眠调节：在神经生物学研究中越来越多地使用系统发生原始的哺乳动物。在八只成年雪貂中收集二十四小时S-W基线数据。在光照开始时，七只白鼬被剥夺睡眠6小时。像其他胎盘哺乳动物一样，雪貂表现出清醒，快速眼动（REM）睡眠和非REM（NREM）睡眠的主要警觉状态。有趣的是，雪貂的REM睡眠量要高得多（24。总录音时间的01±1.61％）比典型的胎盘哺乳动物报道的要高。由于睡眠剥夺在恢复期间NREM EEG三角洲功率显着增加，因此鼬睡眠受到统一调节。因此，白鼬睡眠在大多数方面与其他胎盘哺乳动物的睡眠相当。然而，在这个系统发育更古老的物种中大量的REM睡眠表明REM睡眠在哺乳动物进化的早期阶段可能已经出现了更多的数量。
