ORN_VA4 [FBbt_00067051]

Adult olfactory receptor neuron (ORN) that expresses Or85d (Benton et al., 2025). Its dendrite transduces signals from maxillary palp basiconic sensillum pb3 and it responds to 2-phenethyl acetate and phenethyl propionate (Benton et al., 2025). It innervates antennal lobe glomerulus VA4, 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 15-20 of these cells on each side (Grabe et al., 2016; Benton et al., 2025).
