TMS-evoked movements. Mean proportion (± SE) of TMS-evoked movements as a function of time that fell (A) outside the ± 30° zone around the baseline direction, or (B) inside the ± 30° zone around the precue. Baseline, preparatory, and response intervals are marked by light, medium, or dark grey background, respectively (see Figure 1). Compared to the baseline interval, increasingly more TMS-evoked movements fell outside the baseline zone. Thus, the angles of the TMS-evoked movements were modulated over time, indicating changes in the thumb movement cortical representation. However, there was no increase in the number of TMS-evoked movements that fell into the ± 30° zone around the precued direction. *p < 0.05, **p < 0.01.
