General Information
Term adult olfactory receptor neuron Ir75d ac2 ID (Ontology) FBbt:00110014 (Fly Anatomy)
Definition Olfactory receptor neuron Ir75d with its sensory dendrite in an antennal coeloconic sensillum ac2 (Silbering et al., 2011). It responds strongly to changes in humidity (Yao et al., 2005).[ FlyBase:FBrf0187906 FlyBase:FBrf0206496 FlyBase:FBrf0215822 ]
Also Known As"ionotropic receptor neuron Ir75d ac2" ; "Ir75d ac2" ; "ORN ac2Z" (for all, see Synonyms field below)
CommentThis neuron was indirectly shown to be olfactory by electrophysiological recordings of a single coeloconic sensillum (Benton et al., 2009).
