Abstract

A critical review is presented of the physiological background for the interpretation of ABR auditory brainstem response). The importance of the transformation of the monophasic click stimulus to a dampled oscillation on the basilar membrane, the travelling wave velocity and the synchronization of high frequency units in the auditory nerve are emphasized. The ABR is an expression of the wave front of the leading volley of synchronized action potentials generated in nerve cell bodies in the relay stations of ascending auditory pathway. It is concluded that the physiological evidence for IC as sole, or main generator of wave V is very incomplete. The possibility of multiple generators in the SOC-complex is emphasized.

摘要

本文对用于解释听觉脑干反应(ABR)的生理学背景进行了批判性综述。强调了将单相点击刺激转换为基底膜上的阻尼振荡、行波速度以及听神经中高频单元同步的重要性。ABR是在听觉上行通路中继站的神经细胞体中产生的同步动作电位领先波阵面的一种表现。得出的结论是,关于下丘作为V波唯一或主要发生器的生理学证据非常不完整。强调了在脑干听觉复合体中存在多个发生器的可能性。
