 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
