Results of the simulations. (a) The localization of two EMG-correlated sources is achieved in consecutive steps: with a standard DICS method (top-right panel, sagittal slice) and with DICS combined with regional suppression (bottom right panel). The leftmost source (dip1) is suppressed with a ratio of 30 (source coherence ratio), while the rightmost source is enhanced with a ratio of 17. (b) The localization of a single source with ten different SNR levels (cyan is the lowest and magenta is the highest) is achieved with DICS (top panel). The same simulated source+noise datasets are processed after local removal of noise by means of subspace reprojection (black is the lowest SNR, yellow is the highest).
