Results of Wilcoxon signed-rank tests carried out across subjects to compare the rate of correct responses for sets of trials with highest versus lowest regional beta power integrated in temporal windows between 0.3 s to 3 s (a) and 3.3 s to 3.8 s (b), respectively. Maps of z-values show regions that were significant at p<0.05 uncorrected for multiple comparisons. The thin white lines mark the borders for brain regions with z-values that are significant after adjusting to control the FDR. Positive z-values (red colors) indicate a higher rate of correct responses for trials with highest regional beta power, while negative z-values (blue colors) indicate a higher rate of correct responses for trials with lowest regional beta power. Maps are shown in lateral (upper row) and medial views (middle row) of the two hemispheres, as well as in top and bottom views of the brain (lower row).
