General Information
Term mushroom body output neuron 20 ID (Ontology) FBbt:00111013 (Fly Anatomy)
Definition Mushroom body output neuron whose dendrites arborize in gamma lobe slices 1 and 2, similar to MBON25 (Aso et al., 2014; Li et al., 2020). It also has dendritic arborization outside of the mushroom body, predominantly in the crepine and lateral accessory lobe (Li et al., 2020). Its presynaptic terminals are found in several regions, including the superior and inferior clamp, the superior lateral, posterior lateral and anterior ventrolateral protocerebra, and the superior posterior slope (Li et al., 2020). There is 1 neuron of this type in each hemisphere (Aso et al., 2014; Li et al., 2020).[ FlyBase:FBrf0227179 FlyBase:FBrf0248215 ]
Also Known As"atypical MBON20" ; "MBON-20" ; "MBON20"
