Respiratory period (RP) changes occurring during sleep-waking states were studied during 5- to 8-h recording sessions in chronic cats. RP distribution was clearly trimodal, the shortest mode occurring essentially during alert wakefulness, the largest mode during slow wave sleep and the intermediate mode during drowsy wakefulness. Immediate shifts were observed at instant awakening, whereas after an EEG arousal lasting a few seconds, the RP could remain short for several minutes. Results suggest that the respiratory pattern generator depends upon several attractors.
在对慢性猫进行5至8小时的记录过程中，研究了睡眠 - 觉醒状态下出现的呼吸周期（RP）变化。RP分布明显呈三峰模式，最短的模式主要出现在警觉觉醒期间，最大的模式出现在慢波睡眠期间，中间模式出现在昏昏欲睡的觉醒期间。在即刻觉醒时观察到立即转变，而在持续几秒的脑电图觉醒后，RP可能会在几分钟内保持较短。结果表明，呼吸模式发生器依赖于几个吸引子。
