Quade test: F-values at electrodesPOz and Cz. A Quade test was performed on the energy averaged across single trials, on 100 msec × 15 Hz moving time–frequency windows. F > 3.74 (inwhite) at x msec and y Hz indicates a significant effect (p < 0.05) of the stimulation type in the 100 msec × 15 Hz time–frequency window centered in (x,y). The duration of the significant effect may vary from electrode to electrode, but the effect is always confined to the 30–40 Hz range.
