A Comparison of Moving Dipole Inverse Solutions Using EEG´s and MEG´s

Moving dipole inverse solutions provide a very useful method of estimating the location of an electrical source in the brain from EEG´s or MEG´s measured at the surface of the head. In this method, a dipolar source model is moved about in a model of the head while its amplitude and orientation are also adjusted to obtain the least-squares error fit between the measured EEG´s or MEG´s and those produced by the dipolar source.
