General Information
Term alpha/beta surface/core Kenyon cell ID (Ontology) FBbt:00049838 (Fly Anatomy)
Definition Alpha/beta mushroom body neuron that has dendrites in the main calyx and whose axons form concentrically layered regions of the alpha and beta lobes (Takemura et al., 2017). They are born after the alpha/beta posterior neurons and are organized by birth order, with later-born neurons located more centrally (Takemura et al., 2017; Li et al., 2020). There are around 800-900 of these neurons in each hemisphere (Aso et al., 2014; Takemura et al., 2017; Li et al., 2020).[ FlyBase:FBrf0205263 FlyBase:FBrf0227179 FlyBase:FBrf0236382 FlyBase:FBrf0248215 ]
Also Known As "alpha/beta sc KC" ; "alpha/beta sc Kenyon cell" ; "alpha/beta surface/core KC" (for all, see Synonyms field below)
Comment Sizes of layers are inconsistent between papers: ~500 surface, ~130 outer core, ~260 inner core in Tanaka et al. (2008); Aso et al. (2014); Takemura et al. (2017), ~220 surface, ~350 middle, ~250 core in Li et al. (2020).
