Variation in source localization across methods.

a Peak source locations on the pial surface for visual ERF 1, for each dipole orientation method, in a single subject. b Mean (left) and standard deviation (right) of the Euclidean distance between peak source locations for each method, using the pial surface, over subjects and ERFs. c Time course of source activity for visual ERF 1 for the different methods, at the peak pial source location identified using the downsampled surface normals method, for a single subject. d Mean (left) and standard deviation (right) of the RMSE between source activity time courses at the peak source location identified using the downsampled surface normals method, for each method, using the pial surface, over subjects and ERFs. e Time course of source activity for visual ERF 1 at the peak pial source location identified from each method, for a single subject. f Mean (left) and standard deviation (right) of the RMSE between source activity time courses at the peak source location identified using each method with the pial surface, over subjects and ERFs.
