The influence of model parameters on the inverse solution based on MEGs and EEGs.
The influence of parameters describing the head on the localization of two simultaneous active dipoles is studied. The head is described by a set of five concentric anisotropic spheres. The uncertainties in the conductivity parameters and their effects on the dipole parameters are discussed. Finally the applicability of EEG and MEG is compared.
