Fig. 5.

Response-locked LRP waveforms. Time point zero denotes the registration of the response. Response-locked LRPs are shown across two groups. Data of healthy controls is shown in blue and that of patients with Gilles de la Tourette syndrome (GTS) in red. Standard deviations are represented by shaded areas with pale blue representing healthy controls and pale red GTS. Purple areas show the overlap between the groups. The analyzed time window of the response activation (−300 ms to 0 ms) is marked with horizontal brackets. For the topography plots, difference waves were created between the contralateral and ipsilateral sides in the motor element overlap and in the no motor element overlap conditions, separately in the two groups. The scalp topography plots show the distribution of the mean activity of the contralateral-ipsilateral difference wave of the time window of the response activation (−300 ms to 0 ms). Panel A presents the motor element overlap condition. Panel B shows the no motor element overlap condition.
