General Information
Term adult olfactory receptor neuron Or98a ID (Ontology) FBbt:00067062 (Fly Anatomy)
Definition Adult olfactory receptor neuron (ORN) that expresses Or98a (Benton et al., 2025). Its dendrite transduces signals from antennal basiconic sensillum ab7 and it responds to esters, alcohols and ketones (Benton et al., 2025). Its axon innervates antennal lobe glomerulus VM5v, bilaterally (Benton et al., 2025). It develops from an Nab precursor (Benton et al., 2025). There are approximately 9-12 of these cells on each side (Grabe et al., 2016; Benton et al., 2025).[ FlyBase:FBrf0187305 FlyBase:FBrf0233453 FlyBase:FBrf0262710 ]
Also Known As"adult ORN Or98a" ; "odorant receptor neuron Or98a" ; "ORN (Or98a)" (for all, see Synonyms field below)
