General Information
Term adult Kenyon cell ID (Ontology) FBbt:00049825 (Fly Anatomy)
Definition Kenyon cell of the adult mushroom body. It has its soma in the mushroom body cell body rind (above the calyx) and has dendrites in the main calyx and/or an accessory calyx (Lee et al., 1999; Aso et al., 2014). There are three main subtypes that project their axons to the gamma lobe, the alpha and beta lobes, and the alpha' and beta' lobes (Lee et al., 1999; Aso et al., 2014). All three subtypes are cholinergic (Barnstedt et al., 2016; Croset et al., 2018). In the pedunculus, the Kenyon cell axons are organized by birth order, with gamma neuron axons more peripheral and the last-born (alpha/beta) neurons in the center (Li et al., 2020). There are close to 2000 Kenyon cells per adult mushroom body (Li et al., 2020).[ FlyBase:FBrf0111409 FlyBase:FBrf0227179 FlyBase:FBrf0231313 FlyBase:FBrf0238777 FlyBase:FBrf0248215 ]
