The question mark in the title indicates that what follows is not a theory explaining odor memory, but a series of findings that question the traditional view of memory, in which acquisition and retrieval of ‘memory items’ dominate all questions asked. That such questions arise in an area that deals with odors is not surprising. Odors are the least palpable and most evanescent of stimuli. Odors...

We investigated the effects of odors on appraisal processes and consequent emotional responses. The main goal was to test whether an odor is detected as novel or familiar before it is evaluated as pleasant or unpleasant. Participants performed a recognition task in which they were presented with pairs of unpleasant or pleasant odors (sample and target odors). Within a pair, the sample and targe...

To view the entire series, visit . Odors associated with livestock manure are foremost among complaints made by indi­ viduals who live in the vicinity of concen­ trated animal feeding operations (CAFOs). While some view these odors as nothing more than a nuisance, others are concerned that livestock odors could potentially affect their health. The purpose of ...

Sensory information acquires meaning to adaptively guide behaviors. Despite odors mediating a number of vital behaviors, the components of the olfactory system responsible for assigning meaning to odors remain unclear. The olfactory tubercle (OT), a ventral striatum structure that receives monosynaptic input from the olfactory bulb, is uniquely positioned to transform odor information into beha...

We assessed the influence of different odors on detection of a sweet tastant, and the ability of imagined odors to elicit the same effects as perceived odors on taste perception. The tastant used was sucrose, and the two odorants were strawberry and ham. In the first experiment, participants either smelled or imagined one of two odors during taste detection tasks (between-subject design), where...
