Changes in corticospinal excitability and the direction of evoked movements during motor preparation: A TMS study-3

All precues combined. Black lines show acceleration vectors (magnitude-direction) of individual movements. The thick red line depicts the average angle of movements evoked during the baseline interval (-900 ms). This angle was used to define the baseline zone (± 30°), which is marked in light red. Baseline, preparatory, and response intervals are marked by light, medium, or dark grey background, respectively (see Figure 1). The plots show a decrease in the proportion of TMS-evoked movements that fell into the baseline zone, at the end of the preparatory interval. This proportion further decreased during the response interval.
