OA-VPM3 [FBbt_00110151]

Octopaminergic neuron of the VM cluster, whose cell body is located posterior to that of OA-VPM1 and VPM2, in the mandibular segment of the adult brain. Its main neurite projects to the ventral esophagus where it crosses the midline. It then passes the posterior margin of the contralateral antennal lobe and runs further dorsally to the anterior superior medial protocerebrum. There it turns posteriorly and medially to cross the midline again and to terminate in the ipsilateral middle superior medial and lateral protocerebra. Various processes branch off the main neurite innervating the contralateral superior medial and lateral protocerebra, the fan-shaped body, the contralateral noduli, the contralateral gamma lobe and spur (slices 1, 3, 4 and 5) and outer region of the calyx of the mushroom body (Busch et al., 2009, Busch and Tanimoto, 2010. There is one neuron of this type in each hemisphere. It is synapsed to the MVP2 neuron in mushroom body gamma lobe slice 1 (Sayin et al., 2019. It develops from a larval sVPMmx (OAN-g1) cell (Truman et al., 2023. (Busch and Tanimoto, 2010, Aso et al., 2014, Burke et al., 2012, Truman et al., 2023, Sayin et al., 2019, Busch et al., 2009)

The neurotransmitter was assessed by immunostaining with an anti-octopamine (OA) antibody in cells labelled with tdc2-GAL4 (FBti0101786) and NP7088-GAL4 (FBti0037217) (Busch et al., 2009 or only using the tdc2-GAL4 (FBti0101786) (Busch and Tanimoto, 2010.
