Olfactory Coding: Non-Linear Amplification Separates Smells
How does the nervous system encode complex sensory stimuli? A recent study reveals the fly olfactory system compensates for variability in sensory input as odor representations are restructured for enhanced discriminability and coding efficiency.
متن کاملOlfactory Coding: When Smells Collide
Brain responses can significantly outlast sensory stimuli leading to potential ambiguity when responses overlap. Recent studies of locust olfaction found that the responses of individual second order projection neurons depend markedly on the previous few seconds' stimulus history; the population response, however, still conveys information about both temporal structure and odour identity.
متن کاملChocolate smells pink and stripy: Exploring olfactory-visual synesthesia
Odors are often difficult to identify, and can be perceived either via the nose or mouth ("flavor"; not usually perceived as a "smell"). These features provide a unique opportunity to contrast conceptual and perceptual accounts of synesthesia. We presented six olfactory-visual synesthetes with a range of odorants. They tried to identify each smell, evaluate its attributes and illustrate their e...
متن کاملSwiss identity smells like chocolate: Social identity shapes olfactory judgments
There is extensive evidence that social identities can shape people's attitudes and behavior, but what about sensory judgments? We examined the possibility that social identity concerns may also shape the judgment of non-social properties-namely, olfactory judgment. In two experiments, we presented Swiss and non-Swiss participants with the odor of chocolate, for which Switzerland is world-famou...
