Methods for constructing a real head model from MRI (magnetic resonance imaging) data and its boundary element mesh are proposed. Based on this real head model, forward computations of electroencephalography and magnetoencephalography are investigated and numerical simulation results are presented. Deflation is adopted in order to solve the singularity of discrete system equations in the boundary element method. An isolated problem approach is applied to overcome the smear effect of skull conductivity. An improved auto solid angle algorithm is developed to speed up the computation of kernel matrix
