Hyperbinding effects in patients with GTS

We employ electroencephalography (EEG) to investigate Gilles de la Tourette syndrome (GTS) from a Theory of Event Coding (TEC) perspective. Our research confirms that GTS is characterized by altered binding of sensory and motor codes in dominant sensorimotor routines, highlighting the significance of altered perception-action processing in GTS. This project links GTS's hyperbinding to the Binding and Retrieval in Action Control (BRAC) framework, extending beyond TEC by emphasizing the separation of feature binding and retrieval. We aim to ascertain whether hyperbinding in GTS results from aberrant event-file integration (binding) or event-file retrieval, or both. Given the potential heightened deviant processes with tactile stimuli in GTS, we compare binding and retrieval in vision and touch. This approach enhances our comprehension of GTS-control differences in cognitive processes related to binding effects, offering insights for targeted interventions.
