General Information
Term larval mushroom body output neuron a2 ID (Ontology) FBbt:00047966 (Fly Anatomy)
Definition Larval odd neuron with its soma just posterior to the mushroom body (Mohamed et al., 2023). It receives input in the ipsilateral calyx, predominantly from Kenyon cells (Saumweber et al., 2018; Mohamed et al., 2023), and has presynaptic terminals in the regions surrounding the ipsilateral and contralateral medial lobes (Mohamed et al., 2023). It is involved in odor-based learning (Mohamed et al., 2023) and its activity promotes turning behavior (Eschbach et al., 2021). It develops from neuroblast CP3 (DL2) and becomes adult MBON22 during metamorphosis (Saumweber et al., 2018; Truman et al., 2023).[ FlyBase:FBrf0236359 FlyBase:FBrf0238440 FlyBase:FBrf0251872 FlyBase:FBrf0255928 FlyBase:FBrf0256709 ]
Also Known As "larval MBON-a2" ; "MBE7b"
Comment MBE7b synonym from catmaid.
