Figure 1.

Schematic representation of the apparatus and experimental task. A, Side view of the apparatus. B, Chronology of a typical trial. Appearance of 1 of the 10 targets indicated the beginning of a trial (Target Onset). Movement onset corresponded to when the hand left the starting point (Movement Onset). Vision of the cursor was only provided once the hand crossed the halfway point between the starting point and the target (Cursor Onset). The delivery of the TMS pulse over the left M1 was triggered at movement completion (Movement End).
