Abstract: A new three dimensional imaging method for electroencephalogram (EEG) is suggested. It consists of the solution of an inward spherical harmonic continuation. After introducing the principle of the new method, numerical simulation is made and the feasibility of the method is confirmed by the simulation results. -
