General Information
Term adult olfactory receptor neuron Or22 ID (Ontology) FBbt:00067025 (Fly Anatomy)
Definition Bilateral olfactory receptor neuron (ORN) that expresses Or22a and Or22b (Benton et al., 2025). Its dendrite transduces signals from antennal basiconic sensillum ab3 and it responds to esters (Benton et al., 2025). Its axon innervates antennal lobe glomerulus DM2, bilaterally (Benton et al., 2025). It expresses sNPF (Carlsson et al., 2010). It develops from an Nba precursor (Benton et al., 2025). There are approximately 18 of these cells on each side in males and 28 in females (Benton et al., 2025).[ FlyBase:FBrf0159257 FlyBase:FBrf0187305 FlyBase:FBrf0211156 FlyBase:FBrf0233453 FlyBase:FBrf0262710 ]
Also Known As "adult ORN Or22" ; "adult ORN Or22a" ; "adult ORN Or22b" (for all, see Synonyms field below)
