We introduce a new algorithm, which combines Topographic Matching Pursuit as spatio-temporal decomposition method with a dipole-source localization. The new algorithm is applied to EEG-data obtained from a photic driving experiment with eleven volunteers. In comparison to a hitherto published Multichannel Matching Pursuit (MMP) source localization the new algorithm shows, for a Mirrored-Dipole configuration, higher Goodness-of-Fit values, if temporal asynchrony exists in the EEG-channels. We conclude that the suggested algorithm is more appropriate for source reconstruction in case of temporal asynchrony than MMP-based procedures used so far. article Strohmeier, Daniel Author aut Gratkowski, Maciej Author aut Haueisen, Jens Author aut (DE-588)143795244 Technische Universität Ilmenau Fakultät für Informatik und Automatisierung host institution his BMT 2010.10.05-08 Rostock DGBMT Jahrestagung 44 2010.10.05-08 Rostock 3-Länder-Tagung D-A-CH 2010.10.05-08 Rostock Bd. 55.2010, Suppl. 1, S. 111-113 55, 2010:Suppl. 1, E:55:1<111 Biomed.
