This pilot study in healthy volunteers aims to determine if biological sex has an impact on recovery from dexmedetomidine-induced unconsciousness, and if transcranial magnetic stimulation combined with electroencephalography (TMS-EEG) can be used to measure brain complexity during dexmedetomidine sedation without arousing study participants.
