General Information
Term adult mushroom body ID (Ontology) FBbt:00003684 (Fly Anatomy)
Definition Bilaterally paired neuropil structure situated postero-dorsally in the protocerebrum that functions in olfactory associative learning and memory. The mushroom body is divided into: the calyx, which is closest to the cell body rind and receives sensory interneuron afferents; the pedunculus, which is a thick axon bundle extending from the calyx to the base of the lobes; and the mushroom body lobe system, which consists of a vertical branch composed of two intertwined lobes (alpha and alpha') and a medial branch consisting of three parallel lobes (beta, beta' and gamma) (Crittenden et al., 1998; Ito et al., 2014).[ FlyBase:FBrf0105215 FlyBase:FBrf0224194 FlyBase:FBrf0248215 ]
