| Term | adult medulla-lobula neuron MeLo2 | ID (Ontology) | FBbt:20007251 (Fly Anatomy) |
| Definition | Adult unilateral optic-lobe-intrinsic neuron with its soma lateral to the accessory medulla (Schlegel et al., 2024; Dorkenwald et al., 2024). It bifurcates near the soma, sending one branch to the medulla and one to the lobula, without passing through the optic chiasm (Nern et al., 2025). It receives input in medulla layers M1-4 in around 10-20 columns and has mixed terminals in a few columns of lobula layers 4 and 5A (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 60 of these cells per hemisphere (Nern et al., 2025).[ FlyBase:FBrf0259490 FlyBase:FBrf0260535 FlyBase:FBrf0260545 FlyBase:FBrf0260546 FlyBase:FBrf0262545 ] | ||
| Also Known As | "adult CB3836 neuron" ; "CB3836" ; "MeLo2" (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. | ||
