在麻醉的豚鼠中，在自发发生（7,10,11）和皮质诱导的节律性下颌运动（RJMs）（8,12）期间，已经获得了下颌闭合和张开运动神经元周期性发生的突触电位的细胞内记录。这些电位与皮层诱导rms的产生之间的关系已经在之前的论文中得到了说明(8)。Nakamura和Kubo（23）表明，对瘫痪猫的眶皮层的重复刺激会引起三叉神经运动神经元的节律性膜电位变化，这与在咬肌（颌肌）和二腹肌（颌肌）神经中观察到的交替放电有关。有人提出，生产
Intracellular recordings of cyclically occurring synaptic potentials in jaw-closer and-opener motoneurons have been obtained in the anesthetized guinea pig during spontaneously occurring (7, 10, 11) and cortically induced rhythmical jaw movements (RJMs)(8, 12). The relationship between these potentials and the production of the cortically induced RJMs has been shown in the preceding paper (8). Nakamura and Kubo (23) have shown that repetitive stimulation of the orbital cortex in the paralyzed cat evokes rhythmical membrane-potential changes in trigeminal motoneurons, which are correlated with the alternating discharges that are observed in the masseter (jaw-closer muscle) and digastric (jaw-opener muscle) nerves. It has been proposed that the production of
