Association between masticatory muscle, autonomic and cortical activity during sleep in animal model

在非快速眼动睡眠期间，下颌肌肉活动与自主神经和皮层激活有关。当自主神经活动受到药理学抑制时，这种关联似乎得以保留。与下颌运动控制有关的皮质区域投射到脑干神经元，如三叉神经前运动神经元。唤醒活动，如皮层和自主神经激活可能与下颚运动活动的起源有关，下颚运动活动可能在非快速眼动睡眠期间皮层下行输入的影响下进一步调节。

Jaw muscle activities were associated with autonomic and cortical activation during NREM sleep. This association seems preserved when autonomic activity was pharmacologically suppressed. Cortical areas related to jaw motor control projected to the brainstem neurons such as trigeminal premotoneurons. Arousal activity such as c ortical and autonomic activations can be related to the genesis of jaw motor activity that might be further modulated under the influences of cortical descending inputs during NREM sleep.
