Its dendrite transduces signals from antennal basiconic sensillum ab2 and it responds to acetates and ketones (Benton et al., 2025). Its axon innervates antennal lobe glomerulus DM4, bilaterally (Benton et al., 2025). It develops from an Nba precursor (Benton et al., 2025). There are around 20-30 of these cells on each side (Benton et al., 2025). DoOR:Or59b odorant receptor neuron Or59b
