Figure 1

Examples of (A,B and D) artefact ICs which were excluded and (C) a good IC kept for further analysis. The black dots are positions of channels in the 64-channel EEG system. Colour-coding indicates projection weights of an IC (column of the inverse weight matrix, EEG.icawinv in EEGLAB). Panels A and B demonstrate ICs with topographical sparseness (TS) > 5, that were excluded from further analysis. Panels B and D demonstrate ICs with residual variance (RV) of the equivalent dipoles exceeding 15%. These ICs were also excluded from further analysis. Panel C demonstrates an IC which was kept for further analysis (TS > 5 and RV < 15%).
