A system, controlled by a microcomputer (LSI-11/23 with appropriate peripherals) for conducting evoked potential (EP) experiments, is described. In each experimental trial, a stimulus is applied and multichannel EEG is sampled, displayed, and stored in an output file. Any required length of pre- and poststimulus sampling periods is available. Stimuli are triggered by a human operator, aided by an on-line graphic display of sampled data. Automatic artifact monitoring is used for rejecting bad trials. Various stimulators may be used (simultaneously) and stimulus features (duration, power, number of pulses) may be changed in each trial. Lists of trial parameters, such as stimulus features and subject's response, are incorporated in the output file to facilitate cross-section analysis. The system was designed for the needs of pain EP research, but its flexibility and modularity make it useful in other areas of EP research.
本文描述了一种由微型计算机（带有适当外围设备的LSI - 11/23）控制的用于进行诱发电位（EP）实验的系统。在每次实验试验中，施加一个刺激，并对多通道脑电图进行采样、显示和存储在输出文件中。刺激前和刺激后的采样周期可设置为任何所需长度。刺激由人工操作员触发，并借助采样数据的在线图形显示辅助。自动伪迹监测用于剔除不良试验。可以（同时）使用各种刺激器，并且每次试验中刺激特征（持续时间、强度、脉冲数）可以改变。试验参数列表，如刺激特征和受试者的反应，包含在输出文件中以方便进行横断面分析。该系统是为疼痛EP研究的需求而设计的，但其灵活性和模块化使其在EP研究的其他领域也很有用。
