Fig. 4.

Stimulus-locked lateralized readiness potential (LRP) parameters on a single-subject level. Mean amplitude and onset latency data are shown as group (Gilles de la Tourette: GTS vs. healthy controls: HC) by overlap (Element overlap vs. No element overlap) bar plots separately for the investigated time windows: early incorrect response activation of the Planned Responses (0–200 ms), main correct response activation of the Immediate Response (220–420 ms) and response window of the Planned Responses (600–1000 ms). Individual data points are presented within the bars (Weissgerber et al., 2015). Significant effects of group and overlap are marked with curly brackets.
