Abstract

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.

摘要

描述了一种基于线性代数从头皮场计算皮质表面电位场的新方法。它需要从磁共振图像中获取每个受试者的详细解剖信息。该计算方法在人体头部物理模型中得到验证，并应用于人体受试者。结果表明，该方法能产生可靠的皮质表面场，有助于定位人类诱发的皮质活动。
