General Information
Term larval mushroom body output neuron n1 ID (Ontology) FBbt:00047989 (Fly Anatomy)
Definition Larval neuron with postsynaptic terminals ipsilaterally in all three mushroom body vertical lobe regions (V1, V2 and V3) and in the dorsoposterior compartment (posterior superior medial protocerebrum) (Saumweber et al., 2018). It also has postsynapses and presynapses in the dorsoanterior compartment (anterior superior medial protocerebrum) and basocentral compartment (ventromedial cerebrum) (Saumweber et al., 2018). It develops from neuroblast BAmd1 (Saumweber et al., 2018). It outputs onto FAN-1 (Eschbach et al., 2020).[ FlyBase:FBrf0238440 FlyBase:FBrf0245294 ]
Also Known As"larval MBON-n1" ; "MBE23"
CommentMBE23 synonym from catmaid.
