Effect of CTBS on cortico spinal excitability and reaction times.A, cTBS was applied over left M1 at an intensity of 80% active motor threshold in 50 Hz bursts of three pulses repeated at 200 ms intervals for 40 s. Corticospinal excitability was determined from the mean MEP amplitude recorded in the right FDI muscle following 15 trials of single-pulse TMS. B, Time course of corticospinal excitability after cTBS. Participants were categorized as responders (n = 8) or nonresponders (n = 8) depending on the presence of inhibitory after-effects. C, Mean reaction times of responder and nonresponder participants during both left and right index finger abductions in each MEG recording. Data points represent the mean ± SEM. * indicates significant difference (p <0.05) in reaction time between the two highlighted conditions.
