Fig. 2.

TMS results of the experiment. The two lines depict the MEP amplitude relative to the static hands condition in the action relevant muscle and in the action irrelevant muscle. The action relevant muscle was defined as the muscle involved in executing the observed movement and the action irrelevant muscle as the muscle not involved in executing the observed movement. Error bars represent standard errors of the mean corrected for within-subject designs according to Morey (2008). The TMS results for the two separate muscles are available in supplementary material (Supplementary Figure S1).
