General Information
Term adult olfactory receptor neuron Or85a ID (Ontology) FBbt:00067049 (Fly Anatomy)
Definition Adult olfactory receptor neuron (ORN) that expresses Or85a and Or33b (Benton et al., 2025). Its dendrite transduces signals from antennal basiconic sensillum ab2 and it responds to ethyl-3-hydroxybutyrate (Benton et al., 2025). It innervates antennal lobe glomerulus DM5, bilaterally (Benton et al., 2025). It develops from an Nab precursor (Benton et al., 2025). There are approximately 23 of these cells on each side in females and around 16 in males (Grabe et al., 2016; Benton et al., 2025).[ FlyBase:FBrf0187305 FlyBase:FBrf0187306 FlyBase:FBrf0233453 FlyBase:FBrf0262710 ]
Also Known As "adult ORN Or85a" ; "adult ORN Or85a/33b" ; "odorant receptor neuron Or85a/33b" (for all, see Synonyms field below)
