Prediction accuracy of electrode clusters are in descending order from left to right and from top to bottom. Tukey’s range test was used for all post hoc analysis. Conditions that are significantly different are marked with “*”. PO, rP, lP, rM, lM, FT, MR and EOG represent parietal-occipital, right-parietal, left-parietal, right-motor, left-motor, frontal, medial regions, and the EOG cluster respectively.
