General Information
Term adult olfactory receptor neuron Ir75d ac1 ID (Ontology) FBbt:00110011 (Fly Anatomy)
Definition Olfactory receptor neuron Ir75d with its sensory dendrite in an antennal coeloconic sensillum ac1 (Silbering et al., 2011). It responds strongly to changes in humidity (Yao et al., 2005). There are around 15 of these cells per hemisphere (Grabe et al., 2016).[ FlyBase:FBrf0187906 FlyBase:FBrf0206496 FlyBase:FBrf0215822 FlyBase:FBrf0233453 ]
Also Known As"ionotropic receptor neuron Ir75d ac1" ; "Ir75d ac1" ; "ORN ac1Z" (for all, see Synonyms field below)
CommentNava Gonzales et al. (2021) - FBrf0250923 unsure whether this is ac1C or ac1D.
