MeVP21 [FBbt_20007621]

Adult unilateral visual projection neuron with its soma dorsal to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). It has postsynapses in around 80 columns of the ipsilateral medulla layers M6-M7 (Nern et al., 2025). It has presynapses in the posterior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 3 of these cells per hemisphere (Nern et al., 2025).

Adult Cholinergic 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.
