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). cell body rind of larval maxillary neuromere larval mushroom body modulatory input neuron mushroom body octopaminergic neuron larval mushroom body feed across neuron 2 larval mushroom body two-step feedback neuron 20 larval mushroom body feedforward neuron 35 gnathal ganglion neuron larval gnathal ganglion V1 segment of the vertical lobe embryonic/larval superior clamp bilateral
