'Sniffin' sticks': olfactory performance assessed by the combined testing of odor identification, odor discrimination and olfactory threshold.
'Sniffin' Sticks' is a new test of nasal chemosensory performance based on pen-like odor dispensing devices. It comprises three tests of olfactory function, namely tests for odor threshold (n-butanol, testing by means of a single staircase), odor discrimination (16 pairs of odorants, triple forced choice) and odor identification (16 common odorants, multiple forced choice from four verbal items...
متن کاملOdor identification, consistency of label use, olfactory threshold and their relationships to odor memory over the human lifespan.
The purpose of this study was to investigate olfactory threshold, odor identification, consistency of label use and their relationships to odor memory in the context of semantic/episodic memory across the human lifespan. A total of 137 subjects aged 4-90 years were tested with several olfactory test procedures. We found that olfactory sensitivity was well developed in children despite the findi...
متن کاملMeasurement of Odor Threshold by Triangle Odor Bag Method
The detection thresholds of odor substances analyzed in field investigations were measured by the triangle odor bag method. The number of substances used for the experiment is 223. The experiment was carried out from 1976 to 1988. As the results of the experiments, the odor thresholds were distributed over the concentration of large range depending on the odor substances. Isoamyl mercaptane exh...
متن کاملOffensive-odor substance in the evil-smelling fish from the sea polluted by petroleum and petrochemical industrial waste. 1. Identification of offensive-odor substance.
For the purpose to reveal the substance as the source of offensive odor of the fish from the sea facing petroleum and petrochemical industries, analyses have been made on the sea water, industrial wastes, offensive odor fish meat and the eels kept in the sea or industrial waste for a certain period, by means of gas chromatography, infrared, and ultraviolet absorption spectrophotometries and mas...
متن کاملOlfactory Bulb: Odor Signals Put into Context
In this issue, Doucette and colleagues demonstrate that information related to whether an odor is currently linked to reward can be observed uniquely in population activity in the olfactory bulb, changing our understanding both of what is coded by the first olfactory relay in the CNS and of how this coding is instantiated.
