Larvae and adult flies can be taught to associate odor stimuli with sugar reward, and prior work has implicated both the octopaminergic and the dopaminergic modulatory systems in reinforcement signaling. Here we use genetics to analyze the anatomy, up to the single-cell level, of the octopaminergic/tyraminergic system in the larval brain and subesophageal ganglion. Genetic ablation of subsets of these neurons allowed us to determine their necessity for appetitive olfactory learning. These experiments reveal that a small subset of about 39 largely morphologically distinguishable octopaminergic/tyraminergic neurons is involved in signaling reward in the Drosophila larval brain. In addition to prior work on larval locomotion, these data functionally separate the octopaminergic/tyraminergic system into two sets of about 40 neurons. Those situated in the thoracic/abdominal ganglion are involved in larval locomotion, whereas the others in the subesophageal ganglion and brain hemispheres mediate reward signaling.</dcterms:abstract> <dcterms:issued>2014</dcterms:issued> <dcterms:title>Characterization of the octopaminergic and tyraminergic neurons in the central brain of Drosophila larvae</dcterms:title> <dc:creator>Thum, Andreas S.</dc:creator> <dc:creator>Selcho, Mareike</dc:creator> <dc:contributor>Pauls, Dennis</dc:contributor> <dc:creator>Stocker, Reinhard F.</dc:creator> <dc:contributor>Selcho, Mareike</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/29305"/> <dc:language>eng</dc:language> <dc:contributor>Thum, Andreas S.</dc:contributor> </rdf:Description> </rdf:RDF>
