Figure 2: Results comparing the timing of motor response peaks as determined classically through the root mean square (RMS) across MEG sensors versus motor response peaks as determined by the angle dynamics test. The angle dynamics test used a template defined by the response-locked epoch, which was compared (angle test) at each time point along the cue-locked epoch. Because the cue-locked epoch has been adjusted according to each individual’s RMS defined motor response peak, the zero point on the 𝑥 -axis is the classically defined motor peak. Validating the angle dynamics test, the difference between the within and between angle measures becomes nonsignificant during a 101 ms window around the zero point. Shaded regions show the 95% confidence intervals for the between and within angle measures. The grand average of template and cue-locked responses at 3 different times are depicted on the bottom. As seen in these grand average responses, the cue-locked topography is similar to the response-locked template at the zero point but dissimilar 100 ms before and 100 ms after the zero point.
