Abstract

2nd order finite element method (FEM) algorithm has been developed to solve the anisotropic electroencephalogram (EEC) forward problem and has been evaluated by comparing with analytic solutions in a multi-spheres 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 1st order FEM for comparable numbers of tetrahedron elements.
