Abstract
Extracellular recordings were made from respiratory related units (RRUs) in the pneumotaxic center (PNC) of unanesthetized cats across states of consciousness: wakefulness, NREM and REM sleep. Contrary to expectations from results in acute preparations, well-modulated respiratory activity was detected in chronic animals with vagi intact. Pontine RRU activity decreased during sleep in 75% of the cells studied. The greatest reduction occurred during REM sleep.
摘要
在未麻醉猫的呼吸调整中枢（PNC）中，对处于不同意识状态（清醒、非快速眼动睡眠和快速眼动睡眠）的呼吸相关神经元（RRUs）进行了细胞外记录。与急性实验结果的预期相反，在迷走神经完整的慢性动物中检测到了调制良好的呼吸活动。在所研究的细胞中，75%的脑桥RRU活动在睡眠期间下降。最大的下降发生在快速眼动睡眠期间。
