General Information
Term adult medulla visual projection neuron MeVP15 ID (Ontology) FBbt:20007615 (Fly Anatomy)
Definition Adult visual projection neuron with its soma lateral to the lateral horn (Schlegel et al., 2024; Dorkenwald et al., 2024). In the optic lobe, it is mainly postsynaptic in medulla layers M6-M7, in around 15 columns (Nern et al., 2025). In the central brain, it remains ipsilateral, and sends output to the posterior lateral protocerebrum and mushroom body calyx (Schlegel et al., 2024; Dorkenwald et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 10 of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ]
Also Known As "adult medulla tangential neuron e06" ; "adult MTe06 neuron" ; "MeVP15" (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.
