It bifurcates near the soma, sending one branch to the medulla and one to the lobula, without passing through the optic chiasm (Nern et al., 2025). It receives input, but also has presynapses, primarily in medulla layers M8-9 in around 30 columns (Nern et al., 2025). It also receives input in the lobula, in around 10 columns of layer 3 (Nern et al., 2025). Its predicted neurotransmitter is glutamate (Eckstein et al., 2024; Nern et al., 2025). There are approximately 40 of these cells per hemisphere (Nern et al., 2025). MeLo9 Cell type from Schlegel et al. (2024), based on FlyWire v783 (FAFB) data (Dorkenwald et al., 2024; Schlegel et al., 2024), identified at light level by Nern et al. (2025). Soma location is based on the closest annotated neuropil region in FlyWire. LMa5 VFB:FBbt_20007233 FBbt:20007233 fly_anatomy.ontology CB3818 adult CB3818 neuron MeLo9 unilateral
