Effect of stimulation sessions on TA and SOL MEP recruitment curves. MEP areas before (SOL, white; TA,light gray) and after (SOL, black; TA,dark gray) participation in the patterned (A; n = 6), combined (B; n = 10), and TMS-alone (C; n = 5) stimulation sessions. Error bars indicate group means with SEs. TMS intensity is expressed on the x-axis as percentage of stimulator output relative to motor threshold (MT).
