A realistic head model with anisotropic conductivity is simulated by the finite volume method, which is based on the integral conservation equation. A new mesh discretization method is presented to simulate the realistic head model with anisotropic conductivity. With the method, it is convenient to calculate anisotropic problems with curved boundary surfaces, and the calculation accuracy can be enhanced. The results are compared with analytical solutions of spherical models. The comparison shows that the finite volume method is of high calculation accuracy
