<qa>  What is the relationship between tics and voluntary movement in patients with Tourettes syndrome?This study examines the spatiotemporal dynamics of cortical functional interconnectivity involved tics and voluntary movement in patients with Tourettes syndrome or chronic motor tic disorder. By employing a combination of EEG methods that utilize analyses in the domains of both frequency e.g., event-related desynchronizationsynchronization ERDERS, event-related partial coherence, phase coherence and time e.g., event-related partial correlation, we intend to determine
