General Information
Term adult hygrosensory neuron Ir68a ID (Ontology) FBbt:00047222 (Fly Anatomy)
Definition Ipsilateral hygrosensory neuron that expresses the Ionotropic receptor (Ir) 68a as well as the co-receptor Ir93a (Frank et al., 2017; Knecht et al., 2017). There are two subtypes, with dendrites in chamber I or II of the sacculus, projecting to glomeruli VP1m or VP5, respectively (Frank et al., 2017; Marin et al., 2020).[ FlyBase:FBrf0235932 FlyBase:FBrf0236232 FlyBase:FBrf0246456 ]
Also Known As "HRN Ir68a" ; "ionotropic receptor neuron Ir68a"
Comment FBrf0235932 and FBrf0236232 have contradictory results regarding expression of Ir25a in these cells.
