ORN_VA3 [FBbt_00067023]

Adult olfactory receptor neuron (ORN) that expresses Or67b (Benton et al., 2025). Its dendrite transduces signals from antennal basiconic sensillum ab9 and it responds to alcohols (Benton et al., 2025). Its axon innervates antennal lobe glomerulus VA3, bilaterally, fasciculating with the antennal lobe commissure (Kaur et al., 2019). It develops from an Nab precursor (Benton et al., 2025). There are around 15 of these cells on each side (Benton et al., 2025).
