我们研究了大鼠下咽缩肌和胸骨舌骨肌在非快速眼动(Non-REM)和快速眼动睡眠(REM)时的呼吸活动。每只动物都携带着长期植入的电极，用于记录呼吸肌的综合肌电活动以及皮层脑电(ECoG)和姿势张力(背颈肌电)。后者允许多导睡眠图识别睡眠状态。在非快速眼动睡眠中，蜷曲姿势增强了双上呼吸道肌肉的吸气活动，并且除了良好的卷曲姿势外，CO2呼吸不能增强这种效果。低氧降低了它们的活性。在REM睡眠中，咽下缩肌和胸骨舌骨肌保持其吸气活动。在两块肌肉中均未检测到紧张性活动。我们得出结论，在两种主要睡眠状态下，下咽缩肌和胸骨舌骨肌保护上呼吸道通畅。
We studied the respiratory activity of the inferior pharyngeal constrictor and sternohyoid muscles of the rat during non-rapid eye movement (non-REM) and REM sleep. Each animal carried chronically implanted electrodes for recording the integrated EMG activity of respiratory muscles as well as the electrocorticogram (ECoG) and postural tone (dorsal neck EMG). The latter permitted polygraphic identification of sleep states. Curled up postures enhanced inspiratory activity of both upper airway muscles during non-REM sleep, and effect which CO2breathing failed to augment except in the well curled up position. Hypoxia reduced their activity. During REM sleep, the inferior pharyngeal constrictor and sternohyoid muscles retained their inspiratory activity. No tonic activity could be detected in either muscle. We conclude that the inferior pharyngeal constrictor and sternohyoid muscles safeguard upper airway patency in the two main sleep states.
