It responds to pyrrolidine (Benton et al., 2025). There are three subclasses, which all innervate only the ipsilateral antennal lobe glomerulus VL1, with dendrites transducing signals from different antennal coeloconic sensilla (Silbering et al., 2011; Kaur et al., 2019). They all develop from an Naa precursor (Benton et al., 2025). ionotropic receptor neuron Ir75d DoOR:Ir75d VFB:FBbt_00047054 ORN_VL1 antennal olfactory receptor neuron precursor Naa antennal olfactory receptor neuron of coeloconic sensillum adult antennal lobe receptor neuron unilateral antennal lobe receptor neuron
