General Information
Term larval mushroom body input neuron b1 ID (Ontology) FBbt:00047958 (Fly Anatomy)
Definition Larval neuron with postsynaptic terminals in the centroposterior lateral compartment (clamp), centroposterior medial compartment (posterior inferior protocerebrum) and basoposterior medial compartment (ventromedial cerebrum) and presynaptic terminals in the mushroom body pedunculus (Saumweber et al., 2018). It receives input from FFN-31 (Eschbach et al., 2020). It develops from the DPLd neuroblast (Saumweber et al., 2018) and remodels into a dopaminergic PAL neuron that innervates the optic lobe during the pupal stage (Truman et al., 2023).[ FlyBase:FBrf0238440 FlyBase:FBrf0245294 FlyBase:FBrf0255928 ]
Also Known As"MBE10a" ; "MBIN-b1"
CommentMBE10a synonym from catmaid.
