A, B, During the Go/No Go task, MEP amplitudes in the right FDI, shown normalized to the WS time point (colored lines, left y-axis), were suppressed more for AP currents than for PA currents at the IS compared with the WS (A), indicating a selective anticipatory suppression in response to the WS. However, during successful No Go trials of the Go/No Go task, MEP amplitudes normalized to the IS were suppressed to a similar extent for AP currents as for PA currents at 70%RT when compared with those at the IS (B), indicating a similar reactive suppression in response to the No Go signal. The facilitation of MEPs in Go trials at 70%RT was similar for both current directions. Voluntary rms EMG measured before the TMS pulse (colored bars, right y-axis) is shown normalized to values at the WS (A) and IS (B), and was similar for PA and AP currents across different time points for Go and No Go trials. *p < 0.05, **p < 0.01, compared with IS time point within each current direction; +p < 0.05, AP vs PA.
