Abstract
A new method is described to calculate epicortical potential fields fr om scalp fields based on linear algebra. It requires detailed anatomic al information, for each subject, obtained from MR images. The calcula tion is validated in a physical model of the human head and applied to human subjects. The results suggest that the method yields reliable e picortical fields that help to localize evoked cortical activity in hu mans.
