General Information
|
| Term |
EB neuron of the dopaminergic PPM3 cluster |
ID (Ontology) |
FBbt:00110327 (Fly Anatomy) |
| Definition |
Extrinsic ring neuron that is part of the dopaminergic PPM3 cluster and innervates the bulb and the lateral surface of the lateral accessory lobe, bilaterally (Omoto et al., 2018). It projects along the lateral ellipsoid fascicle, entering the ellipsoid body at a dorsolateral position (Omoto et al., 2018). It has mainly postsynaptic terminals in the lateral accessory lobe and mixed terminals in the outer central (sparse) and outer posterior (concentrated) domains of the ellipsoid body (Omoto et al., 2018; Hulse et al., 2021). Its terminals in the bulb are mostly presynaptic (Hulse et al., 2021). There are two of these cells per hemisphere and they develop from neuroblast DM6 (Kandimalla et al., 2023).[ FlyBase:FBrf0049409 FlyBase:FBrf0220041 FlyBase:FBrf0240929 FlyBase:FBrf0254510 FlyBase:FBrf0257023 ] |
| Also Known As |
"ExR2" ; "extrinsic ring neuron ExR2" ; "PPM3-EB" |
| Comment |
ExR2 was not fully reconstructed by Hanesch et al. (1989), so although it is thought that they are represented by this class, it is possible that the Hanesch et al. (1989) ExR2 neurons are the Omoto et al. (2018) ExR4 neurons (Omoto et al., 2018). |
