Abstract

Gross auditory nerve action potentials to high-frequency clicks were recorded bilaterally from awake cats with unilaterally tenotomized middle ear muscles (MEM) during eating and during control quiet periods. Masking by internally generated noise associated with eating increased with decreases in click intensity, but did not differ in ears with intact and tenotomized MEM. Under the conditions of this study, non-reflex MEM activity does not appear to provide protection against masking by internally generated noise.

摘要

在清醒的猫进食期间和对照安静期，对单侧切断中耳肌肉（MEM）的猫双侧记录了对高频滴答声的粗大听觉神经动作电位。与进食相关的内源性噪声引起的掩蔽效应随滴答声强度降低而增加，但在MEM完整和切断的耳朵中并无差异。在本研究条件下，非反射性MEM活动似乎不能提供针对内源性噪声掩蔽的保护作用。
