General Information
Term adult antennal lobe projection neuron VA4 lPN ID (Ontology) FBbt:00007446 (Fly Anatomy)
Definition Adult uniglomerular antennal lobe projection neuron from the ALl1 dorsal hemilineage with dendrites that mainly innervate antennal lobe glomerulus VA4 (Bates et al., 2020). The axons of these neurons innervate a small area at the dorsoposterior edge of the lateral horn. There is around one of these per hemisphere, it fasciculates with the medial antennal lobe tract and it is cholinergic (Bates et al., 2020).[ FlyBase:FBrf0146916 FlyBase:FBrf0174482 FlyBase:FBrf0209355 FlyBase:FBrf0246460 ]
Also Known As "iACT (VA4)" ; "mALT (VA4)" ; "VA4 lPN" (for all, see Synonyms field below)
