General Information
Term MB-alpha neuron of the dopaminergic PPL1 cluster ID (Ontology) FBbt:00110320 (Fly Anatomy)
Definition PPL1 cluster dopaminergic neuron with axonal projections to the tip of the mushroom body alpha lobe (segment 3) (Mao and Davis, 2009; Aso et al., 2014) in both hemispheres (Li et al., 2020). Most of its dendritic arborizations are found in the superior medial and lateral protocerebrum, with a smaller amount in the superior intermediate protocerebrum and lateral horn (Aso et al., 2014). There is one neuron of this type in each hemisphere (Aso et al., 2014; Li et al., 2020) and it develops from the first intermediate neuronal progenitor the CP3 (DL2) neuroblast to be born during larval development (Wang et al., 2014; Ren et al., 2016).[ FlyBase:FBrf0208427 FlyBase:FBrf0223600 FlyBase:FBrf0227179 FlyBase:FBrf0233706 FlyBase:FBrf0248215 ]
Also Known As"PPL1-06" ; "PPL1-alpha3" ; "PPL106"
CommentThe PPL1 cluster was identified by TH immunostaining and using a TH-GAL4 driver (FBtp0020119).
