The activity of single motor units of the splenius-capitis muscle of healthy human subjects and patients with unilateral vestibular lesions was recorded by means of microelectrodes. The major part of these units reacted to vestibular stimulation in the same way as primary and secondary vestibular neurones of other vertebrates. The reactions of these units to trapezoidale stimuli is identical to that of vestibular neurones. An angular acceleration of more than 0.6 degrees/s2 is for these units a stimulus which is above threshold, this too corresponds to findings in the vestibular nerve. In patients with unilateral vestibular lesions the threshold for rotatory stimuli is markedly increased on the side of the lesion, whereas the threshold on the other side remains constant. This method is very sensitive and vestibular lesions can be detected which cannot be seen using the common technics for vestibular examination.
通过微电极记录健康人体受试者和单侧前庭病变患者斜方肌单运动单位的活动。这些单位的大部分对前庭刺激的反应方式与其他脊椎动物的初级和次级前庭神经元相同。这些单位对梯形刺激的反应与前庭神经元的反应相同。对于这些单位来说，超过0.6度/秒²的角加速度是高于阈值的刺激，这也与前庭神经的研究结果相符。在单侧前庭病变患者中，病变侧旋转刺激的阈值明显升高，而另一侧的阈值保持不变。这种方法非常敏感，可以检测出使用常规前庭检查技术无法发现的前庭病变。
