General Information
Term adult antennal lobe projection neuron VP5+VP2 l2PN ID (Ontology) FBbt:00111340 (Fly Anatomy)
Definition Adult unilateral antennal lobe projection neuron whose dendrites mainly innervate the antennal lobe glomeruli VP5 and VP2 (Marin et al., 2020). It fasciculates with the transverse antennal lobe t10ALT tract and innervates the posterior slope and posterior lateral protocerebrum, in some cases reaching the lateral horn (Frank et al., 2015; Liu et al., 2015; Marin et al., 2020). This neuron responds to heating (Frank et al., 2015; Liu et al., 2015). There are one or two of these cells per hemisphere and they are part of the ALl1 (BAlc) ventral hemilineage (Bates et al., 2020; Marin et al., 2020).[ FlyBase:FBrf0227880 FlyBase:FBrf0227881 FlyBase:FBrf0246456 FlyBase:FBrf0246460 ]
Also Known As "VP5+VP2 l2PN" ; "VP5+VP2_l2PN" ; "warm-PN"
Comment Tract and glomeruli updated according to Marin et al. (2020). Classified as uniglomerular by Bates et al. (2020), despite two glomeruli in name.
