Figure 2. Effects of single and paired pulse TMS of the left PMd on the excitability of contralateral M1.

Figure 2

A single CS2 induced an inhibition of approximately 20% in the amplitude of the MEP evoked by contralateral M1 stimulation (depicted as a continuous line on the graph with the dotted line representing the s.e.m.). Paired pulse stimulation of left PMd modulated the interhemispheric inhibition towards the contralateral M1 depending on the ISI between the subthreshold CS1 and the supra-threshold CS2 conditioning stimuli. Intracortical inhibition was found for the ISIs of 1 ms and 5 ms. A, group result for the effects of the single CS2 and the paired pulse at different ISIs. B, individual results. Each line represent a single subject (n = 12). Error bars represent s.e.m. Asterisks indicate P-values < 0.05.
