General Information
Term adult olfactory receptor neuron Or47a ID (Ontology) FBbt:00067054 (Fly Anatomy)
Definition Adult olfactory receptor neuron (ORN) that expresses Or47a and Or33b (Benton et al., 2025). Its dendrite transduces signals from basiconic sensillum ab5 and it responds to esters (Benton et al., 2025). It innervates the antennal lobe glomerulus DM3 bilaterally, fasciculating with the antennal lobe commissure (Kaur et al., 2019). It develops from an Nba precursor (Benton et al., 2025). There are approximately 30 of these cells on each side (Grabe et al., 2016; Benton et al., 2025).[ FlyBase:FBrf0179238 FlyBase:FBrf0187305 FlyBase:FBrf0233453 FlyBase:FBrf0243918 FlyBase:FBrf0262710 ]
Also Known As "adult ORN Or47a" ; "odorant receptor neuron DM3" ; "odorant receptor neuron Or47a" (for all, see Synonyms field below)
