It sends a posterior projection towards the midline, where it bifurcates, branching into both hemispheres with a symmetrical morphology (Stocker et al., 1990; Bracker et al., 2013). After receiving input in the V glomerulus, it follows the lateral antennal lobe tract, bifurcates, and sends processes into the mushroom body calyx and the lateral horn (Bracker et al., 2013). In the calyx, it synapses to multiple types of Kenyon cell (Bracker et al., 2013). There is one of these per hemisphere and it is cholinergic (Bracker et al., 2013; Bates et al., 2020). It responds to carbon dioxide (Lin et al., 2013) and is required for carbon dioxide avoidance in starved, but not fed flies (Bracker et al., 2013). Equivalent to the biVPN in Bracker et al. (2013), as these two neurons have matching descriptions and only one corresponding type found by Bates et al. (2020) in a comprehensive EM analysis. fly_anatomy.ontology bilateral V relay interneuron PNV-1 V ilPN VFB:FBbt_00003995 bilateral V-relay interneuron adult biVPN neuron V_ilPN FlyBrain_NDB:10366 FBbt:00003995 adult bilateral ventral projection neuron bVI V_ilPN uniglomerular antennal lobe projection neuron calyx of adult mushroom body chemosensory system neuron cell body rind of adult subesophageal zone adult uniglomerular antennal lobe projection neuron of SEZ bilateral antennal lobe projection neuron antennal lobe projection neuron to mushroom body adult antennal lobe projection neuron to lateral horn adult cholinergic neuron lateral antennal lobe tract projection neuron adult uniglomerular antennal lobe projection neuron V adult subesophageal zone chemosensory behavior
