General Information
Term alpha/beta surface Kenyon cell ID (Ontology) FBbt:00110930 (Fly Anatomy)
Definition Alpha/beta mushroom body neuron that has dendrites in the main calyx and projects axons to the surface layer of the alpha and beta lobes, where they form a continuous layer surrounding the alpha/beta core (Aso et al., 2014). There are around 500 of these neurons in each hemisphere (Aso et al., 2014; Takemura et al., 2017).[ FlyBase:FBrf0162233 FlyBase:FBrf0174482 FlyBase:FBrf0227179 ]
Also Known As "alpha/beta s KC" ; "alpha/beta s Kenyon cell" ; "alpha/beta surface KC" (for all, see Synonyms field below)
Comment Li et al.(2020) - FBrf0248215 only class ~220 cells as surface, rest likely to be 'middle' group.
