本文介绍了一种在IBM-pC/XT和长城0520微型机上开发的脑诱发电位CNV计算机处理系统,该系统的软件部分使用汇编语言和BASIC语言混合编写,共有六个功能模块,可由选择菜单方便地加以调用。该系统处理速度快,可实时完成EEG信号的采集、叠加平均、记录、回放、图形显示、测量、计算、图形打印和结果存储。在与北医精神卫生研究所合作的关于“神经症病人和正常人伴随负变化的初步观察”研究中,已对76例样本进行了处理,实践证明了该系统具有转换精度高、功能齐全、操作简便、通用性强的特点。 This paper introduces a CNV computer processing system developed on IBM-pC / XT and Great Wall 0520 microcomputers. The software part of the system is written in assembly language and BASIC language. There are six functional modules, which can be conveniently selected menu To be called. The system processing speed, real-time EEG signal acquisition, stacking, recording, playback, graphics display, measurement, calculation, graphics printing and result storage. In the study of “preliminary observation of patients with neurosis and normal subjects with negative changes”, in cooperation with the Institute of Mental Health of Beijing, 76 samples have been processed and proved to have high conversion accuracy, complete functions, Easy to operate, versatile features.
