An EEG forward solution using second-order anisotropic FEM.
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.
