OA-VUMa2 [FBbt_00110157]

Octopaminergic neuron of the VUMa cluster with bilaterally symmetrical projections that branch from the primary neurite at the region ventrolateral to the esophagus foramen (Busch et al., 2009. In each hemisphere, it extends to the posterior margin of the antennal lobe and bifurcates (Busch et al., 2009. One branch ramifies within the antennal lobe, with panglomerular arborization (Bates et al., 2020 and runs further to the anterior subesophageal ganglion (Busch et al., 2009. The second branch joins the medial antennal lobe tract and innervates the lateral horn (Busch et al., 2009; Bates et al., 2020. In addition, there are numerous terminals in the calyx of the mushroom body (Busch et al., 2009. There are two neurons of this type (Aso et al., 2014; Bates et al., 2020. They develop from the larval OAN-a1 and OAN-a2 neurons (maxillary and mandibular sVUM1 neurons) (Truman et al., 2023. (Busch et al., 2009, Truman et al., 2023, Frechter et al., 2019, Aso et al., 2014, Bates et al., 2020)

Octopaminergic neuron of the VUMa cluster with bilaterally symmetrical projections that branch from the primary neurite at the region ventrolateral to the esophagus foramen (Busch et al., 2009.

(Busch et al., 2009, Truman et al., 2023, Frechter et al., 2019, Aso et al., 2014, Bates et al., 2020)

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.
