In this paper, a finite difference method (FDM) was implemented to solve the electroencephalogram (EEG) forward problem for three-concentric-sphere model with skull burr hole. The influence on the EEG forward solutions of the holes in the skull was studied by comparing the forward potential distributions with and without a hole. Computer simulations suggested that the influence of a hole on the EEG recordings strongly depended on the dipole location and orientation. For a radial dipole, the strongest effect on the EEG occurred when it was located below the center of the hole, while for a tangential dipole the strongest effect occurred when it was located below the border of the hole.
