octopaminergic VPM2 neuron obsolete descending neuron of the gnathal ganglion DNg104 2024-02-05T12:00:00Z true DNxn072 FBbt:20007475 fly_anatomy.ontology Obsoleted, as mapped to OA-VPM2 in Bates et al. (2025) - doi:10.1101/2025.07.31.667571. Type identified at light level and matched across EM datasets by Sturner et al. (2025). Pre- or post-synapse locations are those with the highest total count of these neurons in FlyWire FAFB. Adult descending neuron with its soma in the gnathal ganglion, ventral to the prow (Schlegel et al., 2024; Dorkenwald et al., 2024). It is a putative embryonic-born neuron (Schlegel et al., 2024; Dorkenwald et al., 2024). It has its postsynapses and presynapses mainly in the contralateral anterior ventrolateral protocerebrum and the gnathal ganglion (Schlegel et al., 2024; Dorkenwald et al., 2024). In the VNC, it follows the dorsal lateral tract of ventral cervical fasciculus (Sturner et al., 2025). Its predicted neurotransmitter is octopamine (Eckstein et al., 2024). There are approximately 2 of these cells per organism (Schlegel et al., 2024; Dorkenwald et al., 2024; Sturner et al., 2025).
