자스민 농도변화가 뇌활성과 감성에 미치는 영향

Abstract

This study investigated the convergence of the QEEG and mood state changes in healthy females from teens totwenties on the inhalation of jasmine oil in different concentrations (0.01~100%). Brain activity upon stimulationby different concentrations was analyzed based on the RPVs and CVB, representing a rate of change comparedwith the background QEEG. The emotions elicited through jasmine were evaluated on a 20-point scale. The resultof this evaluation showed that jasmine deactivated fast alpha but activated theta. In addition, it provided evidencefor changes in the frequency band according to concentration. As concentration increased, the effect of alphainhibition decreased, while the effect of inhibition of the high frequency band (20~50 Hz) increased. SEF50 andSEF90, which indicate the state of arousal, decreased as the jasmine concentration increased. Furthermore, it wasassessed as having a pleasant, feminine, fresh and soft odor. Therefore, this study suggested that the inhalationof jasmine oil affected brain wave activities and mood states.
