For olfactory stimulation, odors are commonly incorporated into a constant airstream that carries odor molecules to the receptor organ (air-delivered stimulation). Such odor delivery works well for odors of high volatility (naturally effective over long distances) but less or not at all for low-volatile odors (usually only received at short range). We developed a new odor stimulation technique especially suited for low-volatile odors and compared it with conventional air-delivered stimulation using 2 neurophysiological approaches. Odor-loaded dummies were moved into close vicinity of the receptor organs on the antenna of the Florida carpenter ant Camponotus floridanus (dummy-delivered stimulation). Neuronal activity was monitored either at receptor neuron level using electroantennography or in the first olfactory neuropile, the antennal lobes, using calcium imaging. We tested 3 odors of different volatility: C. floridanus’ highly volatile alarm pheromone undecane, its low-volatile trail pheromone nerolic acid, and an even less volatile, behaviorally active C23 alkene, cis-9-tricosene. For low-volatile odors, dummy-delivered stimulation was particularly efficient. We conclude that dummy-delivered stimulation is advantageous compared to the commonly used air-delivered stimulation when studying an animal’s detection and processing of low-volatile odors.</dcterms:abstract> <dcterms:bibliographicCitation>First publ. in: Chemical Senses 35 (2010), 4, pp. 323-333, doi: 10.1093/chemse/bjq022</dcterms:bibliographicCitation> <dcterms:issued>2010</dcterms:issued> <dc:creator>Rössler, Wolfgang</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-06-14T08:01:36Z</dcterms:available> <dc:contributor>Brandstaetter, Andreas Simon</dc:contributor> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:language>eng</dc:language> <dc:contributor>Rössler, Wolfgang</dc:contributor> <dc:creator>Brandstaetter, Andreas Simon</dc:creator> <dc:contributor>Kleineidam, Christoph</dc:contributor> <dcterms:title>Dummies versus Air Puffs : Efficient Stimulus Delivery for Low-Volatile Odors</dcterms:title> <dc:creator>Kleineidam, Christoph</dc:creator> </rdf:Description> </rdf:RDF>
