Abstract

A simple method is presented which by subtraction of amplitudes of averaged evoked potentials (AEP) within regular time-intervals enables us to estimate differences in the course of the potential. First results demonstrate that all parts of the potential may be influenced and that most striking differences must not necessarily occur in the peak region of the AEP. The late negative complex of the AEP is likely to be a result of summation of some subcomponents, which may be altered differently. The method presented allows exact measurements of each of them.

摘要

本文提出了一种简单的方法,通过在规则时间间隔内减去平均诱发电位(AEP)的振幅,使我们能够估计电位过程中的差异。初步结果表明,电位的所有部分都可能受到影响,而且最显著的差异不一定出现在AEP的峰值区域。AEP的晚期负复合波可能是一些子成分叠加的结果,这些子成分可能会有不同的变化。所提出的方法允许对它们中的每一个进行精确测量。
