General Information
Term adult hygrosensory neuron Ir68a VP5 ID (Ontology) FBbt:00049659 (Fly Anatomy)
Definition Adult hygrosensory neuron Ir68a that innervates antennal lobe glomerulus VP5 and innervates a sensillum housed in chamber II of the sacculus (Frank et al., 2017; Knecht et al., 2017; Marin et al., 2020). In VP5, it synapses to antennal lobe projection neuron VP1m+VP5 (Frank et al., 2017). It develops from an Naa precursor (Benton et al., 2025). There are around 7-9 of these cells per hemisphere (Marin et al., 2020).[ FlyBase:FBrf0235932 FlyBase:FBrf0236232 FlyBase:FBrf0246456 ]
Also Known As "HRN Ir68a VP5" ; "HRN_VP5" ; "ionotropic receptor neuron Ir68a VP5" (for all, see Synonyms field below)
Comment FBrf0235932 and FBrf0236232 have contradictory results regarding expression of Ir25a in these cells. Synapsing with PN in VP5 shown by GRASP (Frank et al., 2017).
