Auditory middle latency responses were recorded from healthy right-handed subjects. Acoustic clicks at a rate of 10/s were presented to the subjects via headphones. Using the electrode combination unilateral mastoid-nose tip, responses characterized by two early negative waves (about 11.5 and 18 ms peak latencies), followed by a late positive one (about 30 ms peak latency), were elicited by binaural stimulation (50-dB SL clicks). The waveform of responses from the unilateral mastoid-nose tip combination was similar to that recorded from a combination of the same side mastoid and a balanced noncephalic reference electrode, although the phase was opposite to that recorded from the Cz-unilateral mastoid combination. Auditory middle latency responses were recorded simultaneously from right mastoid and left mastoid and referenced to the nose tip; interaural differences in amplitude were found in most subjects. The amplitudes of the early components for binaural stimulation were larger than those for monaural stimulation.
从健康的右利手受试者记录听觉中潜伏期反应。以每秒10次的速率通过耳机向受试者呈现听觉点击声。使用单侧乳突-鼻尖电极组合，双耳刺激（50分贝感觉级点击声）可引出以两个早期负波（峰值潜伏期约为11.5和18毫秒）随后是一个晚期正波（峰值潜伏期约为30毫秒）为特征的反应。单侧乳突-鼻尖组合的反应波形与从同侧乳突和平衡的非头部参考电极组合记录的波形相似，尽管相位与从Cz-单侧乳突组合记录的相反。同时从右乳突和左乳突记录听觉中潜伏期反应并以鼻尖为参考；在大多数受试者中发现了双耳间的振幅差异。双耳刺激的早期成分的振幅大于单耳刺激的振幅。
