摘要： 颅顶慢反应(slow vertex response,SVR)属于长潜伏期听觉诱发电位,是由声刺激诱发大脑皮层神经元发生的生物电变化,潜伏期为50～500ms。它是电反应测听术中发现和应用最早的一种客观测听方法,可评估听觉系统传导通路的功能性。本文介绍了SVR的概念、神经发生源、实验室检测技术以及SVR的影响因素,包括刺激声参数、受试者的意识状态、年龄和成熟度,并对其在临床和法医学鉴定中的应用进行了综述。

Abstract: Slow vertex response(SVR) is one of long latency auditory evoked potentials. It is a biological and electric response originating from brain cortical neuron evoked by sound stimulus with the latency from 50 to 500 milliseconds. Of all the neuroelectric physiological audiometries,it is the earliest method applied in assessing the function of the auditory neural conduction pathway. The concept,neural generators of SVR have been introduced in this article. Influencing factors on SVR were discussed such as stimulus parameters,consciousness state,age,maturation of the subject. Applications of SVR in clinical and forensic medicine identification were also discussed.
