Abstract
Human myogenic potentials evoked by clicks have been recorded, both from the external acoustic meatus and from the post-auricular region, by means of an average response computer. The configuration of the response was triphasic; a negative-positive-negative wave with extremely short latency of the peaks (about 10 to 25 msec). The focus of the response seemd to be localized a restricted area of the post-auricular region. It was a relatively consistent and low-threshold response. The magnitude of the response was amplified to a great extent by the forward flexion of the neck. The post-auricular response was interpreted to be cochlco- myogenic in origin. In short, the post-auricular response could be used as an indicator of objective audiometry. Furthermore, in principle, there is a possibility that the response may be applied in an electrophysiological method of differentiating various otoneurogenic disorders associated with lesions in the brainstem.Keywords
