Several studies have shown that a woman's vaginal or axillary odors convey information on her attractivity. Yet, whether such scents induce psychoneuroendocrinological changes in perceivers is still controversial. We studied if smelling axillary and vulvar odors collected in the periovulatory and late luteal phases of young women modify salivary testosterone and cortisol levels, as well as sexu...

Previous positron emission tomography studies of right-handed individuals show that the left orbitofrontal cortex is dominant during emotional processing of odors. We collected functional magnetic resonance imaging data from 28 subjects to study this network as a function of odor hedonic valence (pleasant vs. unpleasant), active hedonic judgments versus passive sensation of hedonically charged ...

23 In colonies of eusocial Hymenoptera cooperation is organized through social odors, and 24 particularly ants rely on a sophisticated odor communication system. Neuronal information 25 about odors is represented in spatial activity-patterns in the primary olfactory neuropile of the 26 insect brain, the antennal lobe (AL), which is analog to the vertebrate olfactory bulb. The 27 olfactory syste...

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 ...
