General Information
Term adult mushroom body lateral accessory calyx ID (Ontology) FBbt:00048332 (Fly Anatomy)
Definition A small bar-shaped subregion of the adult mushroom body that protrudes from the anterior dorsolateral edge of the calyx, lateral to the dorsal accessory calyx (Jenett et al., 2012). It contains the postsynaptic terminals of a subpopulation of around 14 alpha'/beta' Kenyon cells (Yagi et al., 2016; Li et al., 2020), some of which only receive input in this region (Marin et al., 2020). It also contains some of the postsynaptic terminals of the gamma-s2 Kenyon cell (Marin et al., 2020; Li et al., 2020). The vast majority of presynapses in this region are from the temperature-sensitive antennal lobe VP3 vPN and VP2 adPN projection neurons (Marin et al., 2020; Li et al., 2020).[ FlyBase:FBrf0219813 FlyBase:FBrf0232885 FlyBase:FBrf0246456 FlyBase:FBrf0248215 ]
