A method for plotting isopotential maps of EEG fields is described. Forty-eight EEG channels are recorded, computer-processed, and used to plot a chart of the potential distribution every msec. This technique shows the usual characteristics of the EEG, and also some parameters that are normally hidden, such as the shape, surface and slope of the waves. The components of the visual evoked potential, for example, appear to be 'saltatory', as they do not move from one place of the scalp to another.
本文描述了一种绘制脑电图等电位图的方法。记录48个脑电图通道，进行计算机处理，并用于每隔一毫秒绘制一张电位分布图。该技术显示了脑电图的常见特征，还显示了一些通常隐藏的参数，如波形的形状、表面和斜率。例如，视觉诱发电位的成分似乎是“跳跃式的”，因为它们不会从头皮的一个位置移动到另一个位置。
