Interventions/Control_1

Phenylethyl alcohol (rose-like odor) will be presented at REM sleep during nocturnal sleep at sleep chamber of laboratory, as odor condition. At a later day, odorless stimuli will be also presented as control condition. The effect of odor on brain potential will be obtained by comparison between control and odor condition.

Interventions/Control_2

Odorless stimuli will be presented at REM sleep during nocturnal sleep at sleep chamber of laboratory, as control condition. At a later day, Phenylethyl alcohol (rose-like odor) will be also presented as odor condition. The effect of odor on brain potential will be obtained by comparison between control and odor condition.
