MeVP63 [FBbt_20007657]

Adult unilateral visual projection neuron with its soma ventral to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). In the optic lobe, it receives input in around 50 columns of medulla layer M6 (Nern et al., 2025). Its main output region is the posterior lateral protocerebrum, where it also has some postsynapses (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is GABA (Eckstein et al., 2024; Nern et al., 2025). There is one of these cells per hemisphere (Nern et al., 2025).

Adult GABAergic Nervous system Visual system

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.
