However, the differences we found after the onset of the motor activities (0 − 1000 ms) were significant in C3 ( Z = 2.245, p = 0.025, Wilcoxon signed-rank test), and almost significant in C4 ( Z = 1.949, p = 0.052, Wilcoxon signed-rank test), with lower power activity in reality in both hemispheres.
