描述了一种基于线性代数从头皮场计算皮层势场的新方法。它需要从 MR 图像中获得每个受试者的详细解剖信息。该计算在人体头部的物理模型中得到验证，并应用于人类受试者。结果表明，该方法产生可靠的外皮层场，有助于定位人类诱发的皮层活动。
A new method is described to calculate epicortical potential fields from scalp fields based on linear algebra. It requires detailed anatomical information, for each subject, obtained from MR images. The calculation is validated in a physical model of the human head and applied to human subjects. The results suggest that the method yields reliable epicortical fields that help to localize evoked cortical activity in humans.
