Comparing the Performance of Popular MEG/EEG Artifact Correction Methods in an Evoked-Response Study

Figure 1

Topographical plots of MMN responses (without correction for internal artifacts). Showing topographical plots of MMN responses to the mistuning deviants, which elicited the strongest and most consistent MMN responses in the tested sample in the EEG (a), MEG magnetometers (b), and MEG gradiometers (c). The plots are based on grand averages from uncorrected data (only preprocessed with tSSS) by applying a time window from 125 to 155 ms after the tone onset.
