General Information
|
| Term |
adult medulla visual centrifugal neuron MeVC21 |
ID (Ontology) |
FBbt:20007301 (Fly Anatomy) |
| Definition |
Adult unilateral visual centrifugal neuron with its soma dorsal to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). In the central brain, it receives input in the posterior lateral protocerebrum (Schlegel et al., 2024; Dorkenwald et al., 2024). In the optic lobe, it has postsynapses in lobula layer 6, across around 30 columns, and pre- and post-synapses in medulla layers M7-M8 across around 60 columns (Nern et al., 2025). Distinct branches innervate each optic neuropil region without passing through the optic chiasm (Nern et al., 2025). There are approximately 3 of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0260535 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ] |
| Also Known As |
"adult cM08a neuron" ; "adult medulla visual centrifugal neuron 08a" ; "cM08a" (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. Discrepancy in predicted NT between EM datasets. |
