General Information
Term adult bilateral antennal lobe projection neuron VP1l+VP3 ilPN ID (Ontology) FBbt:00111339 (Fly Anatomy)
Definition Bilateral adult antennal lobe projection neuron with its soma in the lateral subesophageal zone (SEZ) and dendrites that innervate antennal lobe glomeruli VP3 (Stocker et al., 1990) and VP1l (Marin et al., 2020). It crosses the midline in the SEZ and has symmetrical innervation in both hemispheres (Marin et al., 2020). It fasciculates with the medial antennal lobe tract mALT (Stocker et al., 1990) to innervate the mushroom body calyx and lateral horn (Marin et al., 2020). There is one of these cells per hemisphere (Marin et al., 2020).[ FlyBase:FBrf0051437 FlyBase:FBrf0246456 ]
Also Known As "VP1l+VP3_ilPN" ; "VP3 bACTI" ; "VP3 bilateral PN"
Comment Previously called adPN in label, but references say bilateral VP3 neuron is subesophageal (Stocker et al., 1990; Marin et al., 2020). Originally thought to be an AL-mPN2 (Tanaka et al., 2012 - FBrf0219809), but later discovered to be biglomerular (Marin et al., 2020).
