General Information
Term adult olfactory receptor neuron Or49b ID (Ontology) FBbt:00067061 (Fly Anatomy)
Definition Adult olfactory receptor neuron (ORN) that expresses Or49b (Benton et al., 2025). Its dendrite transduces signals from antennal basiconic sensillum ab11 and it responds to methylphenols and indole (Benton et al., 2025). Its axon innervates antennal lobe glomerulus VA5, bilaterally (Benton et al., 2025). It develops from an Nba precursor (Benton et al., 2025). There are around 6-8 of these cells on each side (Benton et al., 2025).[ FlyBase:FBrf0179238 FlyBase:FBrf0187305 FlyBase:FBrf0233453 FlyBase:FBrf0262710 ]
Also Known As"adult ORN Or49b" ; "odorant receptor neuron Or49b" ; "ORN (Or49b)" (for all, see Synonyms field below)
CommentPreviously thought to innervate ab6, corrected to ab11 in Benton et al. (2025).
