Abstract
The accuracy of boundary element solutions to the forward EEG problem in terms of either triangle potentials or nodal potentials are compared. At the scalp surface, for identical meshes, vertex potentials are less accurate. The loss in accuracy can be recovered, however, by doubling the mesh size
