General Information
Term adult multiglomerular antennal lobe projection neuron VP4+VP2+VL1 l2PN ID (Ontology) FBbt:00111341 (Fly Anatomy)
Definition Adult multiglomerular antennal lobe projection neuron whose dendrites mainly innervate the antennal lobe glomeruli VP4, VP2 and VL1 in both hemispheres (Marin et al., 2020; Bates et al., 2020). There is one of these cells per hemisphere and it belongs to the ALl1 (BAlc) ventral hemilineage (Marin et al., 2020; Bates et al., 2020). It fasciculates with the ipsilateral transverse antennal lobe t3ALT tract to innervate the lateral horn, posterior slope and posterior lateral protocerebrum, unilaterally (Frank et al., 2015; Liu et al., 2015; Marin et al., 2020). This neuron responds to fast increases and decreases in temperature (Liu et al., 2015).[ FlyBase:FBrf0227880 FlyBase:FBrf0227881 FlyBase:FBrf0246456 FlyBase:FBrf0246460 ]
Also Known As "VP4+VL1_l2PN" ; "VP4+VP2+VL1 l2PN" ; "warm-cool-PN"
Comment Glomeruli of arborization updated in Marin et al. (2020). Mapped to VP4+VL1_l2PN based on body ID in Marin et al. (2020) and neuprint notes.
