AB - The purpose of this study is the pursuance of useful evaluation index which can estimate the different
impression obtained by inhalation of several olfactory stimuli. For this purpose, the principal factors
which could determine the impression of olfactory stimulus were attempted to identify. Then the heart
rate variability and the cerebral nervous activity were monitored as physiological response. Furthermore
the relationship among the factor scores of principal factors and these physiological responses were
investigated. As the result, the principal factor of ‘relaxation’ could be estimated accurately with the
concentration of the oxy haemoglobin in comparison with index of heart rate variability.
