Abstract

An interactive PC-based computer controlled system is described that can be used for collection and analysis of data of Visual Evoked Potentials (VEPs). Visual stimuli are generated on a high-resolution color monitor driven by an Enhanced Graphics Adaptor (EGA). The VEP waveforms are digitized by an A/D converter at a sampling rate of 1 KHz and stored on a hard disk for further analysis. The analysis software includes both time and frequency analysis routines as well as some innovative techniques for the use of the VEPs as a diagnostic measure for various diseases.

摘要

描述了一种基于个人计算机的交互式计算机控制系统，该系统可用于收集和分析视觉诱发电位（VEP）数据。视觉刺激由增强图形适配器（EGA）驱动的高分辨率彩色显示器生成。VEP波形由A/D转换器以1kHz的采样率数字化，并存储在硬盘上以供进一步分析。分析软件包括时间和频率分析程序，以及一些将VEP用作各种疾病诊断手段的创新技术。
