Structure of the rTMS sessions: the rTMS intervention, which uses one of four pulse shapes in a 1 Hz, 1000 pulse train at 97.5% of resting motor threshold (MT), is preceded by an approximately 13 minute excitability probing train (80 pulses comprising equal numbers of four different probing pulse conditions) to establish a baseline. A corresponding probing train (180 pulses) is applied immediately after the rTMS intervention to quantify excitability changes. The rTMS and probing pulse shapes are defined and illustrated in Figure 2.
