Case selection. Our study initially included 40 individuals between 18 and 65 years old. We excluded 12 patients because of restlessness or other non-cooperative behaviors before anesthesia. We then examined the EEG data of the remaining 28 patients and excluded 8 patients due to poor data quality (Poor electrode contact and other reasons). Ultimately, we analyzed the EEG data from 20 patients
