General Information
|
| Term |
centrifugal neuron C2 |
ID (Ontology) |
FBbt:00003743 (Fly Anatomy) |
| Definition |
Adult centrifugal neuron with arborizations in the medulla layers M1, M5/M6, M8 and M10 and more restricted arborizations in the lamina (Fischbach and Dittrich, 1989; Kind et al., 2021). In the medulla, it makes reciprocal connections to lamina monopolar neuron L1, and is presynaptic to L2 and L5, as well as medullary intrinsic neuron Mi1 (Takemura et al., 2013). It is GABAergic (Fei et al., 2010). There is usually one of these cells per optic column (Nern et al., 2025).[ FlyBase:FBrf0049410 FlyBase:FBrf0054529 FlyBase:FBrf0205531 FlyBase:FBrf0210635 FlyBase:FBrf0216925 FlyBase:FBrf0222324 FlyBase:FBrf0252485 FlyBase:FBrf0262545 ] |

| Comment |
Pre- versus postsynaptic innervation in the proximal medulla was inferred by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB. Connectivity in the medulla was extrapolated from serial EM of 7 columns from a single sample (Takemura et al., 2013). |
