听觉诱发电位及其法医学应用价值

当一定强度的声音刺激听觉器官时,听觉系统会发生一系列的电活动,这些电活动被称为听觉诱发电位(AEP)。根据听觉诱发电位潜伏期的长短,可将其分为短、中、长潜伏期诱发电位。不同潜伏期听觉诱发电位反映听觉神经通路不同部位的脑功能活动,在法医学鉴定中可以用于听功能与听觉通路病变的客观评定。本文综述了不同听觉诱发电位产生的机制、特征及其在法医学上的应用价值。

Auditory evoked potentials and their application value in forensic medicine

When auditory organ is stimulated by some tones,there will be a series of electric activities in our auditory systems,we call them auditory evoked potentials.we can divide them short,middle and long latency response by their latencies.Different potentials can reflect brain function activities in different pathes of auditory nerve.In forensic medicine expertise,they can be objective evaluation in audition function and handicap of pathes of auditory nerve brain function.In this article,we summarized the mechanism and characters of different auditory evoked potentials,sumed up their application value in forensic medicine.
