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

Figure 4

Percentagewise baseline standard deviation (STD) and signal STD reduction achieved by applying ICA or SSP methods in comparison to the level (at 0% STD) in the raw data recording with tSSS only. Median values are shown in microvolts (μV), femtoteslas (fT), and femtoteslas per centimeter (fT/cm). Outliers more than 1.5 interquartile ranges from the edge of the 50% of the cases are denoted with circles. Case numbers are provided for each outlier.
