Abstract

A 2^nd order finite element method (FEM) algorithm has been developed to solve the anisotropic electroencephalogram (EEG) forward problem and has been evaluated by comparing with analytic solutions in a multispheres concentric head model. The present simulation study indicates that the 2^nd order FEM provides substantially enhanced numerical accuracy and computational efficiency, as compared with the 1^st order FEM for comparable numbers of tetrahedron elements.
