A finite difference method for solving the three-dimensional EEG forward problem.
A finite difference method (FDM) has been implemented to solve the electroencephalogram (EEG) forward problem. This method has been evaluated by means of computer simulations, by comparing with analytic solutions in a three-sphere concentric head model. The effects of dipole eccentricity, spacing of finite difference model and number of grid nodes on solution accuracy are also addressed in the simulations. The simulation results suggest that the FDM can achieve satisfactory forward solution due to a dipole source.
