General Information
Term larval maxillary VPM neuron ID (Ontology) FBbt:00047749 (Fly Anatomy)
Definition Octopaminergic, bilaterally-paired neuron of the maxillary neuromere of the larval subesophageal ganglion. There is one of these neurons per hemisphere. They form a cluster with the VUM neuron cell bodies, but unlike the VUM neurons, the VPM neurons are restricted to the CNS (Selcho et al., 2014). The maxillary VPM neuron has its postsynaptic sites mainly in the subesophageal ganglia of both hemispheres and presynaptic sites in the contralateral mushroom body lower vertical lobe (V1 region), as well as the centroposterior lateral compartment (clamp) and the dorsoanterior and dorsoposterior compartments (superior medial protocerebrum) (Saumweber et al., 2018). It receives input from FAN-2, FB2N-20 and FFN-35 (Eschbach et al., 2020). During metamorphosis, it becomes an adult octopaminergic VPM3 neuron (Truman et al., 2023).[ FlyBase:FBrf0225919 FlyBase:FBrf0238440 FlyBase:FBrf0245294 FlyBase:FBrf0255928 ]
