Flies avoid futile climbing attempts by processing parallax-motion vision to estimate gap width. To identify neuronal substrates of climbing control, we screened a large collection of fly lines with temporarily inactivated neuronal populations in a novel high-throughput assay described here. The observed climbing phenotypes were classified; lines in each group are reported. Selected lines were further analysed by high-resolution video cinematography. One striking class of flies attempts to climb chasms of unsurmountable width; expression analysis guided us to C2 optic-lobe interneurons. Inactivation of C2 or the closely related C3 neurons with highly specific intersectional driver lines consistently reproduced hyperactive climbing whereas strong or weak artificial depolarization of C2/C3 neurons strongly or mildly decreased climbing frequency. Contrast-manipulation experiments support our conclusion that C2/C3 neurons are part of the distance-evaluation system.</dcterms:abstract> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/35029"/> <dc:creator>Korff, Wyatt</dc:creator> <dc:contributor>Nern, Aljoscha</dc:contributor> <dc:contributor>Triphan, Tilman</dc:contributor> <dcterms:issued>2016</dcterms:issued> <dc:contributor>Korff, Wyatt</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-08-16T12:01:38Z</dc:date> <dc:contributor>Naiman, Daniel Q.</dc:contributor> <dc:creator>Strauss, Roland</dc:creator> <dcterms:rights rdf:resource="http://nbn-resolving.de/urn:nbn:de:bsz:352-20150914100631302-4485392-8"/> <dc:contributor>Roberts, Sonia F.</dc:contributor> <dc:creator>Naiman, Daniel Q.</dc:creator> </rdf:Description> </rdf:RDF>
