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). FBbt:00110157
