Source Reconstruction Accuracy of MEG and EEG Bayesian Inversion Approaches
Figure 6
Example of localization performances at 0 and 20 dB.
Two asymmetrical, weakly correlated sources are simulated in the forward problem. Symmetrical correlated priors are considered for ARD and GS. The actual simulated dipoles are centered at the dashed circles. EBB performs almost flawlessly at high SNR at high SNR. GS and ARD still show some local maxima in the actual source location at extremely low SNR.
