Term |
adult olfactory receptor neuron Ir84a |
ID (Ontology) |
FBbt:00110007 (Fly Anatomy) |
Definition |
Bilateral olfactory receptor neuron that expresses the Ionotropic receptor (Ir) 84a (FBgn0037501) and the co-receptor Ir8a (FBgn0052704). Its axon branches, with one branch innervating the ipsilateral antennal lobe glomerulus VL2a and the other fasciculating with the antennal commissure and innervating the contralateral antennal lobe glomerulus VL2a (Grosjean et al., 2011; Silbering et al., 2011). Its dendrite transduces signals from the antennal coeloconic sensillum ac4 (Benton et al., 2009). The numbers of these neurons have been estimated to 29.5 in females and 24 in males (Grabe et al., 2016).[ FlyBase:FBrf0206496 FlyBase:FBrf0215822 FlyBase:FBrf0216424 FlyBase:FBrf0233453 ] |
Also Known As |
"ionotropic receptor neuron Ir84a" ; "Ir84a ac4" ; "ORN (VL2a)" (for all, see Synonyms field below) |
Comment |
This neuron was indirectly shown to be olfactory by electrophysiological recordings of a single coeloconic sensillum (Grosjean et al., 2011). |
