“…Previously, two research teams demonstrated that an increase in HR variation typically accompanies an unpleasant odorant inhaling experience (Alaoui-Ismaïli et al, 1997b;Bensafi et al, 2002aBensafi et al, , 2002b. Our findings suggest that the implicit objective measures support the same negative "bias" as the subjective explicit responses.…”

“…To our knowledge, only one study has used an objective measure (eventrelated potential analysis) to investigate the emotional response to odour in depression (Pause et al, 2003). Furthermore, no research has studied the physiological reactivity to odour in depression, while it has been demonstrated that variations in electrodermal (skin conductance, skin resistance), thermovascular (skin blood flow) and cardiorespiratory (instantaneous heart rate) responses could be modulated by odour pleasantness (Alaoui-Ismaïli et al, 1997a, 1997bVernet-Maury et al, 1999;Bensafi et al, 2002a). For instance, it has been shown that decreases in instantaneous HR variation are associated with pleasant odours, while increases in HR variation are associated with unpleasant odours.…”

This study aimed to improve the understanding of hedonic perception in depression using the olfactory modality. We evaluated physiological (heart rate measures) and hedonic responses (subjective rating scale) obtained from 30 unipolar depressed inpatients and 30 healthy controls. The stimuli were two odorants with contrasting hedonic valence, vanillin (pleasant) and butyric acid (foul-smelling), presented at three different concentrations and in nine binary mixtures. Compared to controls, the depressed subjects had significantly increased heart rate response to olfactory stimuli, regardless of valence. These observations were not related to the severity of depression. For both groups, a significant negative correlation was found between the explicit hedonic rating and the implicit instantaneous heart rate measure. Together these pilot findings suggest that unipolar depression is associated with stronger physiological reactions to odorants and a negative bias when processing olfactory stimuli. Further studies are required to confirm these observations in larger groups of depressed subjects.

“…The increase of alpha 2 activity during late exposure (120-150 s) to incense suggests that the odor of incense affects not only the primary olfactory cortex, but also the adjoining cortices. The primary olfactory cortex is connected with the limbic cortex, hypothalamus, hip- pocampus, insular cortex, and orbitofrontal cortex, which are related to emotion and memories [23,24] . Therefore, it is possible that the odor of incense may induce strong emotional responses and memories.…”

To evaluate the effect of the odor of incense on brain activity, electroencephalograms (EEGs) and event-related potentials (ERPs) in a push/wait paradigm were recorded in 10 healthy adults (aged 23–39 years) with normal olfactory function. EEG was recorded from 21 electrodes on the scalp, according to the International 10-20 system, and EEG power spectra were calculated by fast Fourier transform for 3 min before and during odor presentation. ERPs were recorded from 15 electrodes on the scalp before, during and after exposure to incense with intervals of 10 min. In a push/wait paradigm, two Japanese words, ‘push’ as the go stimulus and ‘wait’ as the no-go stimulus, appeared randomly on a CRT screen with equal probability. The subjects were instructed to push a button whenever the ‘push’ signal appeared. Fast alpha activity (10–13 Hz) increased significantly in bilateral posterior regions during incense exposure compared to that during rose oil exposure. The peak amplitudes of no-go P3 at Fz and Cz were significantly greater during incense inhalation. The latencies of go P3 and no-go P3, and the amplitude and latencies of no-go N2 did not change by exposure to the odors of both incense, rose and odorless air. These results suggest that the odor of incense may enhance cortical activities and the function of inhibitory processing of motor response.

“…One is pharmacological, via direct interactions between odor molecules and receptors or nerve endings, and the other is psychological via the subjective experience of odors (Alaoui-Ismaili et al 1997;Heuberger et al 2001;Jellinek 1997). Our results suggest that the principal odor component of jasmine tea, especially, (R)-())-linalool, exerts a pharmacological sedative effect.…”

Sedative effects of the jasmine tea odor and (R)-(−)-linalool, one of its major odor components, on autonomic nerve activity and mood states

We investigated the effects of the odor of jasmine tea on autonomic nerve activity and mood states in a total of 24 healthy volunteers. We used the odor of jasmine tea at the lowest concentration that could be detected by each subject but that did not elicit any psychological effects. R-R intervals and the POMS test were measured before and after inhalation of the odors for 5 min. Both jasmine tea and lavender odors at perceived similar intensity caused significant decreases in heart rate and significant increases in spectral integrated values at high-frequency component in comparison with the control (P < 0.05). In the POMS tests, these odors produced calm and vigorous mood states. We also examined the effects of (R)-(-)-linalool, one of its major odor components, at the same concentration as in the tea, and (S)-(+)-linalool. Only (R)-(-)-linalool elicited a significant decrease in heart rate (P < 0.05) and an increase in high-frequency component in comparison with the controls, and produced calm and vigorous mood states. Thus, the low intensity of jasmine tea odor has sedative effects on both autonomic nerve activity and mood states, and (R)-(-)-linalool, one of its components, can mimic these effects.
