Experimental setup for the on-line experiment. Participants sit in front of a screen with forearms in front of him/her. Bipolar electrodes for FES are attached to participants′ right forearm. A warning sign (a cross) in the middle of the screen instructs the participant to start MI of the right hand. A scale in the left upper corner is proportional to the control parameter of the BCI and moves to the left, towards 0 during MI. This setup was used for conditions 1 and 2.
