检测人体耳大神经动作电位,对鉴别脊髓神经节前和节后纤维的病变有重要意义。关于耳大神经动作电位的测定方法,国内尚未见诸报道。本文介绍一种耳大神经动作电位简便测定方法,并报告国人耳大神经传导速度的正常值及其影响因素,为临床应用提供生理基 Detection of human ear nerve action potential, the identification of spinal ganglia and postganglionic fiber lesions of great significance. About the determination of auricular nerve action potential, has not been reported in China. This article describes a simple method for determining the action potentials of the auricular nerve and reports the normal values ​​of the auricular nerve conduction velocity in humans and their influencing factors to provide physiological basis for clinical application
