Brain stem auditory evoked potentials were recorded simultaneously from the vertex and ear contralateral to stimulation (Ac-Cz) and from the vertex and ear ipsilateral to stimulation (A1-Cz). There was clearer definition of wave V and less latency variability between trials in Ac-Cz channel recordings, resulting in enhanced wave form stability and greater reproducibility of wave I-V interpeak latencies. The clinical interpretation of dual-channel recordings is currently limited by the complexity of the auditory pathways, but the technique itself shows promise as a routine clinical procedure.
在刺激对侧的头顶和耳部（Ac-Cz）以及刺激同侧的头顶和耳部（A1-Cz）同时记录脑干听觉诱发电位。在Ac-Cz通道记录中，V波的定义更清晰，各次试验间的潜伏期变异性更小，从而提高了波形稳定性以及I-V峰间潜伏期的再现性。双通道记录的临床解释目前受听觉通路复杂性的限制，但该技术本身有望成为一种常规临床检查方法。
