Representation of ODors: from physical features
to perceptual processing
Understanding how the human brain represents olfactory objects is a major challenge in cognitive psychology. While the representation of visual objects is well understood, much work remains to be done for smells. MEROD has shown that the mental representation of odour cannot be separated from a high level of variation between individuals.
It is also distributed in multiple ways, between the primary sensory areas for the chemical attributes of odours and the secondary areas for the perceptual attributes.
This representation is significantly disrupted in certain pathologies that affect the sense of smell. These conceptual advances suggest innovative avenues for research on an industrial level (implementing this theoretical knowledge from cognitive psychology in artificial noses) and a clinical level (refining the diagnosis of certain illnesses).

MEROD has contributed to the creation of three new projects : a joint French- German international laboratory, a multidisciplinary European consortium focusing on human and artificial olfaction, and a project to disseminate knowledge about smell.
