medulla-lobula neuron 1 obsolete adult medulla-lobula neuron MeLo1 2024-02-05T12:00:00Z true MLt1 MeLo1 fly_anatomy.ontology FBbt:20007248 adult CB3833 neuron Cell type from Schlegel et al. (2024), based on FlyWire v783 (FAFB) data (Dorkenwald et al., 2024; Schlegel et al., 2024), obsoleted as this is mapped to ML1 (FBbt:20007248) in Matsliah et al. (2024) - FBrf0260545. CB3833 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, but also has presynapses, primarily in medulla layers M1-3, but also in M7-8 in around 10 columns (Nern et al., 2025). In the lobula, it has presynapses in a few columns of layer 6 (Nern et al., 2025). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024; Nern et al., 2025). There are approximately 50 of these cells per hemisphere (Nern et al., 2025).
