However, only recently has dopamine been linked to motivated behaviour and rewarding reinforcement in fruitflies. Instead, octopamine has historically been considered to be the signal for reward in insects. Here we show, using temporal control of neural function in Drosophila, that only short-term appetitive memory is reinforced by octopamine. Moreover, octopamine-dependent memory formation requires signalling through dopamine neurons. Part of the octopamine signal requires the α-adrenergic-like OAMB receptor in an identified subset of mushroom-body-targeted dopamine neurons. Octopamine triggers an increase in intracellular calcium in these dopamine neurons, and their direct activation can substitute for sugar to form appetitive memory, even in flies lacking octopamine. Analysis of the β-adrenergic-like OCTβ2R receptor reveals that octopamine-dependent reinforcement also requires an interaction with dopamine neurons that control appetitive motivation. These data indicate that sweet taste engages a distributed octopamine signal that reinforces memory through discrete subsets of mushroom-body-targeted dopamine neurons. In addition, they reconcile previous findings with octopamine and dopamine and suggest that reinforcement systems in flies are more similar to mammals than previously thought.</dcterms:abstract> <dcterms:isPartOf rdf:resource=""/> <dc:creator>Krashes, Michael J.</dc:creator> <bibo:uri rdf:resource=""/> <dcterms:rights rdf:resource=""/> <dc:contributor>Burke, Christopher J.</dc:contributor> <dc:language>eng</dc:language> <dc:creator>Waddell, Scott</dc:creator> <dcterms:hasPart rdf:resource=""/> <dc:creator>Huetteroth, Wolf</dc:creator> <dcterms:bibliographicCitation>Nature ; 492 (2012), 7429. - S. 433-437</dcterms:bibliographicCitation> <dc:rights>terms-of-use</dc:rights> <dc:contributor>Certel, Sarah</dc:contributor> <dc:contributor>Gohl, Daryl</dc:contributor> <dc:creator>Gohl, Daryl</dc:creator> <dcterms:title>Layered reward signalling through octopamine and dopamine in Drosophila</dcterms:title> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:creator>Perisse, Emmanuel</dc:creator> <dc:contributor>Silies, Marion</dc:contributor> <dspace:isPartOfCollection rdf:resource=""/> <dc:contributor>Waddell, Scott</dc:contributor> <dc:contributor>Krashes, Michael J.</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:creator>Burke, Christopher J.</dc:creator> <dc:contributor>Owald, David</dc:contributor> <dc:contributor>Das, Gaurav</dc:contributor> <dc:creator>Certel, Sarah</dc:creator> <dcterms:available rdf:datatype="">2014-09-05T12:19:30Z</dcterms:available> <dcterms:isPartOf rdf:resource=""/> <dcterms:issued>2012-12-20</dcterms:issued> <dspace:isPartOfCollection rdf:resource=""/> <dspace:hasBitstream rdf:resource=""/> <dc:contributor>Huetteroth, Wolf</dc:contributor> </rdf:Description> </rdf:RDF>
