Electroneurography is an electrophysiologic measurement of compound action potentials elicited by the supramaximal stimulation of a peripheral nerve. The stimulus intensity-response function was examined in the cat facial nerve following stimulation over two different sites of the facial nerve: the main trunk and the buccal branches. Thresholds were achieved at lower current settings, the resultant compound action potential exhibited a greater amplitude, and masseter muscle excitation was more evident following stimulation over the buccal region. The use of concurrent facial- and masseter-evoked electromyographic monitoring allows more sensitive detection of masseter excitation and a more accurate determination of the current level necessary for supramaximal stimulation.
神经电图是对周围神经进行超强刺激所引发的复合动作电位的一种电生理测量方法。在猫的面神经上，于面神经的两个不同部位（主干和颊支）进行刺激后，检测刺激强度 - 反应函数。在较低电流设置下即可达到阈值，由此产生的复合动作电位呈现出更大的幅度，并且在颊部区域进行刺激后咬肌兴奋更为明显。同时使用面部和咬肌诱发的肌电图监测能够更灵敏地检测咬肌兴奋，并更准确地确定超强刺激所需的电流水平。
