The membrane potential of spinal motoneurons was recorded during wakefulness, NREM sleep, and REM sleep in minimally restrained, behaving cats. At the onset of sleep, the membrane potential generally increased in polarization in rough proportion to time spent asleep. During the postural atonia of REM sleep, the membrane potential of all motoneurons was tonically hyperpolarized. Antecedents of NREM sleep electromyographic suppressions, and REM sleep myoclonic twitches were seen as transient hyperpolarizations and depolarizations, respectively.
在轻度束缚、行为正常的猫处于清醒、非快速眼动睡眠和快速眼动睡眠期间，记录脊髓运动神经元的膜电位。在睡眠开始时，膜电位通常会极化增加，大致与睡眠时间成正比。在快速眼动睡眠的姿势性肌张力缺失期间，所有运动神经元的膜电位均呈强直性超极化。非快速眼动睡眠肌电图抑制和快速眼动睡眠肌阵挛抽搐的先兆分别表现为短暂的超极化和去极化。
