Abstract

A technique is described for the recording of multichannel cerebral evoked potential data and their conversion to colour-coded displays of scalp electrical activity at up to 40 instants in time. Such mapping gives a more readily assimilated picture of the evolution of the potential changes over the scalp than the raw waveforms. The method employs a PDP 11/23 computer for data collection and surface topography calculation, and a Tektronix 4662 digital plotter with 8 colour option for the display of spatio-temporal maps.

摘要

本文描述了一种用于记录多通道脑诱发电位数据并将其转换为头皮电活动的彩色编码显示的技术，该显示可呈现多达40个时刻的情况。与原始波形相比，这种映射能更直观地呈现头皮上电位变化的演变情况。该方法采用PDP 11/23计算机进行数据收集和表面地形计算，并使用具有8种颜色选项的泰克4662数字绘图仪来显示时空图。
