General Information
Term adult olfactory receptor neuron Ir64a ID (Ontology) FBbt:00110019 (Fly Anatomy)
Definition Bilateral olfactory receptor neuron that expresses the ionotropic glutamate receptor (Ir) 64a and the co-receptor Ir8a (Benton et al., 2025). There are two subtypes, one that innervates the DC4 glomerulus and one that innervates DP1m (Ai et al., 2010). Its dendrite transduces signals from a grooved sensillum of chamber III of the sacculus (Shanbhag et al., 1995).[ FlyBase:FBrf0084361 FlyBase:FBrf0212455 FlyBase:FBrf0215822 FlyBase:FBrf0262710 ]
Also Known As"ionotropic receptor neuron Ir64a" ; "ORN (Dp1m)" ; "ORN Ir64a"
