| Term | adult olfactory receptor neuron Or88a | ID (Ontology) | FBbt:00067057 (Fly Anatomy) | |||||||||||||||||||||||||||||||||||||||||
| Definition | Adult olfactory receptor neuron (ORN) that expresses Or88a (Benton et al., 2025). Its dendrite transduces signals from antennal trichoid sensillum at4 (Couto et al., 2005; Grabe et al., 2016). It responds to a pheromone secreted by males and females (van der Goes et al., 2007). It innervates the antennal lobe glomerulus VA1d bilaterally, fasciculating with the antennal lobe commissure (Kaur et al., 2019). It develops from an Naa precursor (Benton et al., 2025). There are approximately 40-50 on each side (Benton et al., 2025).[ FlyBase:FBrf0187305 FlyBase:FBrf0192555 FlyBase:FBrf0233453 FlyBase:FBrf0243918 FlyBase:FBrf0262710 ] | |||||||||||||||||||||||||||||||||||||||||||
| Also Known As | "adult ORN Or88a" ; "odorant receptor neuron Or88a" ; "odorant receptor neuron VA1d" (for all, see Synonyms field below) | |||||||||||||||||||||||||||||||||||||||||||
| Comment | ORN Or88a designated as 'at4B' neuron in Gonzales et al. (2021) - FBrf0250923 based on having second largest soma in three-neuron sensillum and presence in two-neuron at4 sensilla. Designated as 'at4C' in Benton et al. (2025) - FBrf0262710. | |||||||||||||||||||||||||||||||||||||||||||
