The introduction in the 60' s of the Nerve Excitability Test (NET) by Laumans and Jongkees for the diagnosis of Bell's palsy stimulated an interest of quantitative testing of the facial nerve. In 1970 Yanagihara reported the Evoced Myography (EMG; i.e. NET is combined with EMG). Starting with electrophysiological basis of the impulse spread of peripheral nerves May, in 1971, extended this concept by including supraliminal stimuli, i.e. Maximal Stimulation Test (MST), for diagnostic purposes. This method eventually developed into what is known as neuronography (Esslen, Huffmann, Ehrenberger, Satoh). It is undoubtedly a refinement in the question of prognosis of Bell's palsy. Continuing the original concept of May we have developed an electronic device with which to carry out automatically the neuronography that demonstrates an evaluation on a numeric display. We use the conventional bipolar negative square wave for a 1 ms stimulation. We stimulate the angle of the mandible, where the ramus marginalis can be readily found in all patients. Neuronography and Evoked Myography provide earlier a more precise prognosis of facial palsy than Nerve Excitability Test (NET). We developed an electronic device for the Maximal Stimulation Test (MST) of May, M., that is automatic. The device counts the spikes of the evoked myogram. A time window is related to the stimulus to exclude stimulus noise and background muscle noise from the counter. Only spikes seen in this window are processed. The number of spikes generated per stimulus is the measurement of the live axons in a stimulated nerve.
20世纪60年代，劳曼斯和容凯斯引入神经兴奋性测试（NET）用于诊断贝尔麻痹，激发了对面神经进行定量测试的兴趣。1970年，柳原报告了诱发肌电图（EMG；即NET与EMG相结合）。梅从外周神经冲动传播的电生理基础出发，于1971年通过纳入阈上刺激，即最大刺激测试（MST），扩展了这一概念用于诊断目的。这种方法最终发展成为所谓的神经描记术（埃斯伦、胡夫曼、埃伦贝格尔、佐藤）。这无疑是贝尔麻痹预后问题上的一项改进。延续梅的原始概念，我们开发了一种电子设备，用于自动进行神经描记术，并在数字显示屏上显示评估结果。我们使用常规双极负方波进行1毫秒的刺激。我们刺激下颌角，在所有患者中都能很容易地找到下颌缘支。与神经兴奋性测试（NET）相比，神经描记术和诱发肌电图能更早地对面神经麻痹做出更精确的预后判断。我们为梅的最大刺激测试（MST）开发了一种自动电子设备。该设备对诱发肌电图的尖峰进行计数。一个时间窗与刺激相关，以从计数器中排除刺激噪声和背景肌肉噪声。只有在这个窗口中看到的尖峰才会被处理。每次刺激产生的尖峰数量是受刺激神经中存活轴突的测量值。
