adult uniglomerular antennal lobe projection neuron V ilPN obsolete adult bilateral ventral projection neuron 2020-05-27T09:02:47Z true Atypical projection neuron of the adult that connects carbon dioxide sensory inputs to the mushroom body calyx (Bracker et al., 2013). There is one of these neurons per hemisphere, with its cell body located lateral to the gnathal ganglion, and it is cholinergic (Bracker et al., 2013). It extends towards the midline, then bifurcates, branching into both hemispheres with a symmetrical morphology (Bracker et al., 2013). It receives input in both V glomeruli, then follows the lALT (oACT), bifurcates, and sends processes into the mushroom body calyx and the lateral horn (Bracker et al., 2013). It synapses to multiple types of Kenyon cell and is required for carbon dioxide avoidance in starved, but not fed flies (Bracker et al., 2013). fly_anatomy.ontology Obsoleted due to equivalence with V ilPN, these two neurons have matching descriptions and only one corresponding type found by Bates et al. (2020) - FBrf0246460 in a comprehensive EM analysis. FBbt:00049525 adult biVPN neuron
