General Information
Term larval mushroom body output neuron b1 ID (Ontology) FBbt:00047960 (Fly Anatomy)
Definition Larval neuron that has postsynaptic terminals in the mushroom body pedunculus and presynaptic terminals in the centroposterior lateral and intermediate compartments (clamp) (Saumweber et al., 2018). It is GABAergic (Eichler et al., 2017). It develops from a BLVa neuroblast (Saumweber et al., 2018), then becomes a lateral horn local neuron during metamorphosis (Truman et al., 2023).[ FlyBase:FBrf0236359 FlyBase:FBrf0238440 FlyBase:FBrf0255928 ]
Also Known As "larval MBON-b1" ; "MBE11a"
Comment Lineage given as BLVa3/4 in Saumweber et al. (2018). MBE11a synonym from catmaid.
