General Information
Term medial lobe of larval mushroom body ID (Ontology) FBbt:00110188 (Fly Anatomy)
Definition The medial lobe of the larval mushroom body. It is associated with appetitive memory (Eschbach et al., 2020).[ FlyBase:FBrf0211533 FlyBase:FBrf0245294 ]
Also Known As "horizontal lobe of larval mushroom body"
Comment At third instar, the medial lobe comprise three types of Kenyon cells: embryonic-born gamma neurons, larval-born gamma neurons and larval born alpha'/beta' neurons (Pauls et al., 2010).
