Unexpectedly, we found that this movement control requires visual opsins. Disrupting the Drosophila opsins NINAE or Rh6 impaired larval locomotion and body contractions, independently of light and vision. Opsins were detected in chordotonal proprioceptors along the larval body, localizing to their ciliated dendrites. Loss of opsins impaired mechanically evoked proprioceptor spiking and cilium ultrastructure. Without NINAE or Rh6, NOMPC mechanotransduction channels leaked from proprioceptor cilia and ciliary Inactive (Iav) channels partly disappeared. Locomotion is shown to require opsins in proprioceptors, and the receptors are found to express the opsin gene Rh7, in addition to ninaE and Rh6. Besides implicating opsins in movement control, this documents roles of non-ciliary, rhabdomeric opsins in cilium organization, providing a model for a key transition in opsin evolution and suggesting that structural roles of rhabdomeric opsins preceded their use for light detection."],["dc.identifier.doi","10.1016/j.neuron.2018.02.028"],["dc.identifier.pmid","29551493"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61475"],["dc.language.iso","en"],["dc.relation.eissn","1097-4199"],["dc.relation.issn","0896-6273"],["dc.title","Proprioceptive Opsin Functions in Drosophila Larval Locomotion"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Efferent activity can provide protection from noise and facilitate the detection and discrimination of sound by modulating mechanical amplification by hair cells and transmitter release as well as auditory afferent action potential firing [1-3]. Insect auditory organs are thought to lack efferent control [4-7], but when we inspected mosquito ears, we obtained evidence for its existence. Antibodies against synaptic proteins recognized rows of bouton-like puncta running along the dendrites and axons of mosquito auditory sensory neurons. Electron microscopy identified synaptic and non-synaptic sites of vesicle release, and some of the innervating fibers co-labeled with somata in the CNS. Octopamine, GABA, and serotonin were identified as efferent neurotransmitters or neuromodulators that affect auditory frequency tuning, mechanical amplification, and sound-evoked potentials. Mosquito brains thus modulate mosquito ears, extending the use of auditory efferent systems from vertebrates to invertebrates and adding new levels of complexity to mosquito sound detection and communication."],["dc.identifier.doi","10.1016/j.cub.2016.05.077"],["dc.identifier.isi","000381241100026"],["dc.identifier.pmid","27476597"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/39818"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Cell Press"],["dc.relation.issn","1879-0445"],["dc.relation.issn","0960-9822"],["dc.title","Auditory Efferent System Modulates Mosquito Hearing"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
