Summary

This study looked at how the brain's emotional centers work in people with Parkinson's disease who had just received a deep brain stimulator implant. Researchers measured brain activity while patients listened to sounds or saw images with emotional meaning. The goal was to better understand how deep brain stimulation affects mood and motivation, not to treat the disease.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patient with Parkinson's disease selected for deep brain stimulation (DBS) of the subthalamic nucleus (STN) in accordance with the criteria established by Welter and colleagues (Welter et al., 2002); * Aged 18 years or above; * Written informed consent from the patient. Exclusion Criteria: * Patient under a legal incapacity or with limited legal capacity; * Patient who has perioperative complications or postoperative confusion; * Patient displaying cognitive disturbances involving the early stages of speech processing (on the basis of an audiogram systematically conducted prior to surgery) ; * Patient displaying cognitive disturbances involving the early stages of face processing (on the basis of the Benton Facial Recognition Test (Benton, Hamsher, Varney, \& Spreen, 1983) systematically administered prior to surgery); * Patient incapable of understanding the information given about the study, performing the tasks or providing informed consent.
