Perception of a blending odor mixture: an fMRI study in humans
Supported by grants from the Burgundy Regional council and EU-ERDF, European Dijon-Dresden Laboratory (LEA 549); Odors we perceive from our environment arise from the processing of mixtures of odorants. Some mixtures can lead to configural or elemental perception depending, in part, on experience. However, the neural bases of such influences are still unknown. In the present study, we examined the neurophysiological correlates of the configural and elemental processing of a binary odor mixture (AB). This AB mixture has previously been shown to blend into one percept, but also to produce a more or less configural perception depending on pre-exposure to either the mixture itself or to the sin…
Impact of proportion on configural perception of odor mixtures in a newborn mammal
International audience; Configural perception of odor mixtures appears functional early in life. Recent results underline that after the learning of a binary mixture. (AB) that blends in humans, newborn rabbits respond both to the mixture and to its components. However, after the learning of. a single component they do not generalize to the mixture. This suggests that they perceive more in the mixture than the odor of each. constituent (Coureaud et al., Physiol. Behav. 2008). Here, we pursued the assessment of their configural perception of AB, with the. aim to determine whether specific component proportions of A and B elicit the perceptual emergence of an additional odor in AB. Starting. …
