Figure 4

Descriptive and interferential statistics of stimulation-induced changes on behavioural level. (A) For the sake of transparency RTs of finger tapping before and after stimulation and subsequent MI practice before calculating the RT% (difference between RTs before and after stimulation) used for the main analysis is presented in this figure. Illustrated is the grand average RT for the hand contralateral to the cathode (cC hand) and the hand contralateral to the anode (cA hand) before (white) and after (grey) stimulation separately for sham and real stimulation conditions. Error bars represent one standard error. The anticipated difference between responses using the hand contralateral to the cathode (cC hand, left hand) and responses using the hand contralateral to the anode (cA hand, right hand) before stimulation is attributable to generally faster responses using the dominant right hand. (B) Interaction between stimulation type and hand considering the RT%. Error bars represent one standard error. *p < 0.05.
