General Information
Term larval mushroom body octopaminergic/tyraminergic neuron e1 ID (Ontology) FBbt:00047973 (Fly Anatomy)
Definition Larval neuron with its soma posterior to the vertical lobe, presynapses in the dorsal tip (V3 segment) of the ipsilateral vertical lobe of the mushroom body and postsynaptic sites in the anterior and posterior superior medial protocerebrum (Saumweber et al., 2018). This neuron is tyraminergic (Eichler et al., 2017). It receives input from FBNs, FB2Ns and FFNs (Eschbach et al., 2020). It develops from the CP3 (DL2) neuroblast and develops into an adult PPL1 SMP-gamma neuron during metamorphosis (Saumweber et al., 2018; Truman et al., 2023).[ FlyBase:FBrf0236359 FlyBase:FBrf0238440 FlyBase:FBrf0245294 FlyBase:FBrf0255928 ]
Also Known As"larval MBE9a" ; "larval OAN-e1"
CommentEichler et al. (2017) refer to this as octopaminergic based on anti-TDC (tyrosine decarboxylase) staining, but this only demonstrates production of tyramine. MBE9a synonym from catmaid.
