General Information
Term adult medulla visual projection neuron MeVP3 ID (Ontology) FBbt:20005420 (Fly Anatomy)
Definition Adult visual projection neuron with its soma ventral to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). It receives input in around 50 columns of medulla layer M8 (Nern et al., 2025). Though it has a projection to the ipsilateral central brain, most of its output is also in medulla layer M8 (Schlegel et al., 2024; Dorkenwald et al., 2024; Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 30 of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "adult medulla tangential neuron e54" ; "adult MTe54 neuron" ; "MeVP3"
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.
