Personalized DBS Targeting for Treating Depression

During the DBS treatment phase, the DBS device will apply electrical stimulation to the patient's target brain regions using a specific strategy, and if the efficacy of this phase is not satisfactory, electrical stimulation will continue to be applied during the efficacy observation phase after DBS shutdown.

SEEG intraoperative experiment: patients will be implanted with microelectrodes and connected to an electrophysiological recorder under local anesthesia. Intraoperative neurophysiological baseline will be recorded for 5 minutes, and esketamine will be injected intravenously at a dose of 0.5 mg/kg, and neurophysiological recordings will be continued for 15 minutes to observe the neuronal electrophysiological changes in various brain regions and target points.
