adult olfactory receptor neuron Or9a [FBbt_00067009]
Bilateral olfactory receptor neuron (ORN) that expresses Or9a (FBgn0030204). Its axon branches, with one branch innervating the ipsilateral antennal lobe glomerulus VM3 and the other fasciculating with the antennal commissure and innervating the contralateral antennal lobe glomerulus VM3. Its dendrite transduces signals from antennal basiconic sensillum ab8. The numbers of these neurons have been estimated to 18 in females and 15 in males (Grabe et al., 2016). Antennal basiconic sensillum ab4 is bidendritic. According to Hallem et al., 2004, adult ORN 43b corresponds to the functionally defined ORN ab8A. We can therefore deduce that adult ORN 9a corresponds to ORN ab8B.
