General Information
Term adult mushroom body dorsal accessory calyx ID (Ontology) FBbt:00045007 (Fly Anatomy)
Definition A small subregion of the adult mushroom body that protrudes from the anterior-dorsal edge of the calyx into the superior lateral protocerebrum (SLP) (Ito et al., 2014). It contains the terminals of the alpha/beta posterior Kenyon cells (Tanaka et al., 2008; Ito et al., 2014; Aso et al., 2014) and it is not separated from the SLP by a glial sheath (Ito et al., 2014). It receives mainly visual input with little, if any, olfactory or gustatory input (Li et al., 2020).[ FlyBase:FBrf0205263 FlyBase:FBrf0224194 FlyBase:FBrf0227179 FlyBase:FBrf0248215 ]
Also Known As"ACA" ; "dACA" ; "dorsal accessory calyx" (for all, see Synonyms field below)
CommentPreviously named the accessory calyx, this was renamed to the dorsal accessory calyx to distinguish it from the ventral accessory calyx (Aso et al., 2014).
