(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. Mi18 Sm32 FBbt:20007269 CB3854 VFB:FBbt_20007269 Mi18 adult CB3854 neuron Adult unilateral medulla intrinsic neuron with its soma ventral to the medulla (Schlegel et al., 2024; Dorkenwald et al., 2024; Nern et al., 2025). It spans around 50 columns, having postsynapses and a smaller number of presynapses in layers M1-2 and M3-4 (Nern et al., 2025). It also receives a small amount of input in layers M7-M8 (Nern et al., 2025). Its predicted neurotransmitter is GABA (Eckstein et al., 2024; Nern et al., 2025). There are approximately 30 of these cells per hemisphere (Nern et al., 2025). fly_anatomy.ontology unilateral
