| Term | medulla-lobula neuron 1 | ID (Ontology) | FBbt:00052137 (Fly Anatomy) | ||||||||
| Definition | Optic lobe neuron that has its soma in the anterior medulla cell body rind, multicolumnar dendritic innervation of the medulla, and an axon that reaches the anterior lobula without passing through the second optic chiasm (Kind et al., 2021). Its dendritic arborization spans approximately 20 optic columns, ramifying in layers M1-4 and M8 from vertical processes (Kind et al., 2021). It receives synaptic input from R8 photoreceptors, mainly in pale optic columns (Kind et al., 2021). Its axon leaves the distal medulla and travels anteriorly to reach layer 6 of the lobula, where it has postsynapses in a few columns (Kind et al., 2021; Nern et al., 2025). In a subpopulation of these cells its axon also innervates the central brain (Kind et al., 2021). It is predicted to be cholinergic (Eckstein et al., 2024; Nern et al., 2025). There are around 45 of these cells per optic lobe (Kind et al., 2021; Nern et al., 2025).[ FlyBase:FBrf0252485 FlyBase:FBrf0259490 FlyBase:FBrf0262545 ] | ||||||||||
