Title

Odour liking physiological indices: a correlation of sensory and electrophysiological responses to odour

Abstract

The perception of smell is dominated by an hedonic dimension, with changes in left and right orbitofrontal activation evident in responses to odours of different valence. Electrophysiological (EEG) recordings were used to investigate differences in hemispheric activation associated with different hedonic responses to a low concentration of a single compound (damascenone: fruity, berry smell). Stimulus delivery (air, or air with odour) was synchronised with inspiration using a continuous respiration olfactometer. EEG responses were analysed using traditional power spectrum techniques to determine the relationship of the brain activity to the reported odour liking responses. Differences in response to the odour were evident in comparison with air, and also between response groups. Using the same odour to evoke different hedonic responses, power spectrum analysis revealed a non-significant trend for left frontal differences in EEG associated with different liking responses to damascenone. This demonstrated quantification of the neurophysiological effects associated with odour liking.
