Experimental paradigm. (A) The timing of an executed or imagined movement cycle (depending on the run) between the home position and one of the four target positions (T1-4). (B) The structure of a block comprising 20 movement cycles between the home position and one of the four target positions. (C) The structure of the runs involving executed and imagined movements. A run involving executed movements is followed by a run involving imagined movements and the runs are separated by inter-run resting (IRR) period. A run comprises four blocks corresponding to each of the four targets (T1-4) and the blocks are separated by an inter-block resting (IBR) period.
