General Information
Term adult olfactory receptor neuron Ir64a DC4 ID (Ontology) FBbt:00111210 (Fly Anatomy)
Definition Adult olfactory receptor neuron Ir64a that innervates the antennal lobe DC4 glomerulus, bilaterally (Ai et al., 2010; Silbering et al., 2011). Its dendrite transduces signals from a grooved sensillum of the ventral compartment of chamber III of sacculus (Shanbhag et al., 1995). It responds to acid (H+ ions) and carbon dioxide (Ai et al., 2010). There are around 10 of these cells on each side (Benton et al., 2025).[ FlyBase:FBrf0084361 FlyBase:FBrf0212455 FlyBase:FBrf0215822 FlyBase:FBrf0222046 FlyBase:FBrf0262710 ]
Also Known As "ionotropic receptor neuron DC4" ; "ORN_DC4"
