A multimodal MR-compatible olfactometer with real-time controlling capability
Journal of Medical Engineering & Technology, 2020Design of an MR-compatible and computer-controlled odour stimuli system is essential in the studies of human olfactory function. Olfactometers are used to deliver odours to the subjects in an objective manner.

‘Sniff Olfactometer (SO) Protocols
2022AbstractMost olfactometers used to study human olfaction have stimulus durations of more than 1 second and often lasting minutes(Dravnieks 1975; Leland et al. 2001; Schmidt and Cain 2010). During long stimulations, olfactory receptor responses and their resulting behaviors are modulated by adaptation and habituation to the stimulus(Pellegrino et al ...

This olfactometer differs from previous models in the materials used in construction and in technical modifications. Plastic tubing and lucite panels were used whenever possible. Two lucite cylinders connected by a small doorway form the insect test cage.

An olfactometer for bark beetle parasites
Journal of Chemical Ecology, 1981An "H"-type olfactometer was designed and built to test the response of bark beetle parasites to various beetle and tree host odors. The design has several advantages over other types of olfactometers. Strong air currents are not utilized, parasites have free movement in the test chamber, and a concentration gradient of test compound is maintained ...

Physics in Medicine and Biology, 1962
The calibration of a precise olfactometer, of which the construction has been reported previously, is described. This includes a determination of the optimal dimensions of the channels and valves necessary for a correct aerodynamic performance. The most convenient scales for the flowmeters are given together with a preliminary determination of ...

Hygroreception in olfactometer studies
Physiological Entomology, 2009Abstract In olfactometric studies, a technique used to measure insect behavioural bias towards airborne chemicals, many of the factors that could affect the bioassay outcome other than the volatiles themselves are carefully controlled (e.g.

Early results of an objective olfactometer
Journal of Medical Engineering & Technology, 1998Although many people comment on their ability or inability to smell an odour, the accurate measurement of olfaction remains an elusive goal. Currently, there are no instruments available to objectively measure olfaction. This article outlines the design and early test results of a low cost, computer-based olfactometer which uses the frequency content ...

The Canadian Entomologist, 1966
AbstractAn olfactometer is described in which an attractive zone is established and maintained in a precisely determined location on the floor (or wall) of an observation chamber and also in the air adjacent to it. Insects must therefore manifest their normal behavior in finding their way to it.

Economical and Disposable Olfactometer
Annals of the Entomological Society of America, 1968In assaying the attractant quality of the aroma produced by the male large milkweed bug, Oncopeltus fasciatus (Dallas), on the female of the species (Lener 1967) I tried various types of olfactometers, but for 1 reason or another none seemed satisfactory. Some were too difficult for me to construct with my limited resources.
