General Information
Term adult antennal lobe projection neuron VP4 vPN ID (Ontology) FBbt:00049752 (Fly Anatomy)
Definition Adult unilateral, uniglomerular antennal lobe projection neuron that develops from the ventral neuroblast (ALv1) and has dendrites that mainly innervate antennal lobe glomerulus VP4 (Marin et al., 2020; Bates et al., 2020). It follows the mediolateral antennal lobe tract to the mushroom body calyx and lateral horn (Marin et al., 2020). There is one of these cells per hemisphere and it is GABAergic (Marin et al., 2020; Bates et al., 2020).[ FlyBase:FBrf0246456 FlyBase:FBrf0246460 ]
Also Known As "VP4 vPN" ; "VP4_vPN"
Comment Bates et al. (2020) lists tract as trans-mlALT.
