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.
