V_ilPN [FBbt_00003995]

Adult uniglomerular antennal lobe projection neuron that arborizes in both V glomeruli and has its soma in the lateral subesophageal zone (Stocker et al., 1990; Bracker et al., 2013; Bates et al., 2020). 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).

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.
