OA-VPM4 [FBbt_00110152]

Octopaminergic neuron of the VM cluster, whose cell body is located posterior to that of OA-VPM3, and slightly lateral, in the labial segment of the adult brain. Its main neurite projects to the ventral esophagus where it crosses the midline. Its secondary neurite shares the tract with OA-VPM3, running further along the posterior margin of the antennal lobe to the anterior superior medial protocerebrum. There it turns posteriorly and medially to cross the midline again along the dorsal margin of the fan-shaped body. Various processes branch off the main and secondary neurites, innervating the contralateral superior, inferior and ventrolateral protocerebra, the whole contralateral gamma lobe and spur of the mushroom body, the subesophageal zone and the ipsilateral middle inferior lateral and middle inferior medial protocerebra (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 and is involved in food odor attraction (Sayin et al., 2019. (Busch and Tanimoto, 2010, Busch et al., 2009, Aso et al., 2014, Sayin et al., 2019)

Octopaminergic neuron of the VM cluster, whose cell body is located posterior to that of OA-VPM3, and slightly lateral, in the labial segment of the adult brain.

(Busch and Tanimoto, 2010, Busch et al., 2009, Aso et al., 2014, Sayin et al., 2019)

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.
