  1. Mean (± SEM) of labelled potentials recorded from labelled electrode sites (FCZ, CP3/4) as a result of median nerve stimulation contralateral to hand movement. Top data from left hand dominant group; bottom data from right hand dominant group. (EBP) early Bereitschaftspotential; (LBP) late Bereitschaftspotential; (MVMT) movement; (PMVMT) post movement. All values are expressed relative to control value (1.00). * denotes significance p < 0.05.
