Figure 6. Effect of variations of properties of the TMS component during PAS on corticospinal excitability in centre/surround representations (Expt 3).

A, top row, symbols refer to different variants of PAS10 used in Expt 3 as described in Table 1. Group data of the changes of the normalized MEP amplitudes of the APB (horizontal stripes) and ADM (vertical stripes) + SEM (black bars) following different PAS variants. §Significant change from baseline. Asterisks indicate significant difference between different PAS10 variants. B, MEP amplitudes from a representative subject before (black) and following PAS (red). Right vertical bars represent calibration bars (0.5 mV). All baseline MEPs are scaled to the same size for better comparison between different interventions.
