Study of Brain Activity During Recovery From General Anesthesia in Adults Undergoing Deep Brain Stimulation Surgery

What this Trial Is About

Researchers are exploring how deep brain nuclei activity and the cerebral cortex function during recovery from general anesthesia in patients undergoing deep brain stimulation DBS surgery. This study aims to understand the changes and connections between deep brain nuclei firing and cortical activity during the return of consciousness. The research focuses on the brains neural networks involved in recovery, which is not just a passive drug clearing process but an active brain function. During the study, patients having DBS surgery will have their local field potentials LFP from deep brain nuclei and scalp electroencephalograms EEG from the frontal cortex recorded simultaneously. No additional interventions are given beyond the planned DBS surgery. These recordings occur during the recovery period after general anesthesia to analyze how signals from deep brain areas relate to cortical EEG activity. Participants will be monitored for changes in brain signals over about 2 hours during recovery from anesthesia. Researchers will evaluate the number of patients showing changes in LFP and EEG patterns. The study includes assessments of brain activity to better understand consciousness recovery mechanisms. Patients are expected to cooperate during surgery and recording, with the total observation focused on the immediate post-anesthesia recovery phase.
