Its dendrite transduces signals from antennal basiconic sensillum ab3 and it responds to esters (Benton et al., 2025). Its axon innervates antennal lobe glomerulus DM2, bilaterally (Benton et al., 2025). It expresses sNPF (Carlsson et al., 2010). It develops from an Nba precursor (Benton et al., 2025). There are approximately 18 of these cells on each side in males and 28 in females (Benton et al., 2025). VFB:FBbt_00067025 FBbt:00067025
