General Information
Term mushroom body calyx ID (Ontology) FBbt:00003685 (Fly Anatomy)
Definition A synaptic neuropil domain containing dendrites of Kenyon cells and receiving sensory interneuron afferents, mainly from the antennal lobes (Ito et al., 2014; Saumweber et al., 2018). It is located on the posterior side of the brain, close to the cortex where the cell bodies of the Kenyon cells are located (Lee et al., 1999; Saumweber et al., 2018). The peduncle extends anteriorly from the calyx to the base of the lobes (Ito et al., 2014; Saumweber et al., 2018).[ FlyBase:FBrf0111409 FlyBase:FBrf0224194 FlyBase:FBrf0238440 ]
Also Known As"CA" ; "calyx of corpora pedunculata" ; "calyx of mushroom body"
