General Information
Term adult medulla visual projection neuron MeVP21 ID (Ontology) FBbt:20007621 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "adult medulla tangential neuron e12" ; "adult MTe12 neuron" ; "MeVP21" (for all, see Synonyms field below)
Comment 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.
