Abstract

The dipole localization method (DLM) of the electroencephalogram (EEG) is investigated based on the high-resolution EEG. The finite volume method (FVM)-boundary element method (BEM) coupled method is used for DLM. For FVM, a novel mesh generation method is presented to overcome the geometric singularity. This method can be employed to calculate EEG forward problems and extended to calculate the high-resolution EEG (HREEG). Because of the high spatial resolution of HREEG, as well as the merits of FVM and BEM, we can expect that the FVM-BEM coupled method is more accurate than the conventional DLM.
