General Information
Term adult olfactory receptor neuron Or13a ID (Ontology) FBbt:00067016 (Fly Anatomy)
Definition Adult olfactory receptor neuron (ORN) that expresses Or13a (Benton et al., 2025). Its dendrite transduces signals from antennal basiconic sensillum ab6 and it responds to alcohols (Benton et al., 2025). Its axon innervates antennal lobe glomerulus DC2, bilaterally (Benton et al., 2025). It develops from an Nba precursor (Benton et al., 2025). There are approximately 10 of these cells on each side (Benton et al., 2025).[ FlyBase:FBrf0187305 FlyBase:FBrf0217319 FlyBase:FBrf0233453 FlyBase:FBrf0262710 ]
Also Known As "adult odorant receptor neuron Or13a" ; "adult ORN (Or13a)" ; "adult ORN ab6A" (for all, see Synonyms field below)
