Multi dipole source identification from EEG/MEG topography

The end goal of source localization problem is to find the parameters of the brain source. The source number is also the case of these parameters. In this paper we consider two system identification methods (e.g., the information criterion method and the F-test method) to determine the dipole number only with one EEG or MEG topography. Then compare the results from these two methods and find the better one. The following investigations are presented to show that the information criterion method used in this paper is an advanced approach for determining the dipole number just with one EEG or MEG topography.
