Behavioral Characteristics of Selected Electroencephalogram Epochs

Selected Electroencephalogram Epochs	Probability of Response to Verbal Stimuli (%) mean (± SD)	Behavioral State
Dexmedetomidine-induced unconsciousness	Not Measured*	Sedation
Propofol-induced unconsciousness (TM)	91.5 (15.4)	Sedation
Propofol-induced unconsciousness (PM)	0	General Anesthesia

^•this study was not structured to measure the probability of response during dexmedetomidine-induced unconsciousness (a sedative dose was administered) due to the sufficient arousal stimulus the auditory tasks posed.

PM: peak max

SD: standard deviation

TM: trough max
