Correlations between scalp regions of interest brain activity and behavioral indices for selected time windows and frequency bands (baseline: 300 ms after movement offset). Significant correlations (abs(r) > 0.6, p < 0.05) are shown in bold. L- and R-CL, left and right centro-lateral scalp regions; L- and R-PL, left and right posterior lateral scalp regions; L- and R-PO, left and right medial pasieto-occipital scalp regions; C-Fr, centro-frontal region; C-Med, centro-medial region; A-Fr, anterior frontal region.
