There is evidence indicating that adrenoceptor mechanisms may influence some of the behaviors in rat. However the role of adrenoceptor agents on sniffing has not been identified. In the present study, the influence of adrenoceptor agents on sniffing induced by apomorphine and amphetamine has been investigated. Male Albino rats, weighing 150-250 g were used for all experiments. The behavior wa...

Sniffing is a specialized respiratory behavior that is essential for the acquisition of odors [1-4]. Perhaps not independent of this, sniffing is commonly displayed during motivated [5-7] and social behaviors [8, 9]. No measures of sniffing among interacting animals are available, however, calling into question the utility of this behavior in the social context. From radiotelemetry recordings o...

Sniffing, a behavior that enhances detection and localization of odorants, is typically assumed to require behavioral arousal. In an effort to determine whether sniffing and arousal are dissociable, dimethyl disulfide (DMDS) was presented to 8-day-old rats while respiration and behavioral state were monitored. Pups sniffed in response to the highest concentrations of DMDS, exhibiting a lower ol...

Many mammals display brief bouts of high-frequency (4-10 Hz) sniffing when sampling odors. Given this, high-frequency sniffing is thought to play an important role in odor information processing. Here, we asked what role rapid sampling behavior plays in odor coding and odor discrimination by monitoring sniffing during performance of discrimination tasks under different paradigms and across diff...

Sniffing has historically been considered an olfactory behavior because inhalation is a necessary step in odor perception. Growing evidence, however, has demonstrated that the display of sniffing surpasses the bounds of those contexts that are olfactory in nature. In this issue of Chemical Senses, Arzi, Shedlesky, Secundo, and Sobel demonstrate that humans mimic visually and auditory-observed s...

A growing body of evidence suggests that sniffing is not only the mode of delivery for odorant molecules but also contributes to olfactory perception. However, the precise role of sniffing variations remains unknown. The zonation hypothesis suggests that animals use sniffing variations to optimize the deposition of odorant molecules on the most receptive areas of the olfactory epithelium (OE). ...
