General Information
Term adult medial equatorial fascicle ID (Ontology) FBbt:00100342 (Fly Anatomy)
Definition Thick fascicle of the adult brain that emerges from cells in the medial posterior rind region below the mushroom body calyx (several lineages) and also contains fibers from the protocerebral bridge (Ito et al., 2014). It branches out in the region inferior-lateral to the fan-shaped body and demarcates the boundaries of the inferior bridge (lateral region), inferior clamp (superior-medial), superior posterior slope (superior region), gorget (superior region) and fan-shaped body (inferior-lateral region) (Ito et al., 2014). Similar to its larval counterpart, it contains components of the CM1/3/4 (DM4-6) and DPMpl3 lineages (Lovick et al., 2013; Hartenstein et al., 2015).[ FlyBase:FBrf0223329 FlyBase:FBrf0224194 FlyBase:FBrf0229672 ]
Also Known As "adult median equatorial fascicle" ; "MEF" ; "protocerebral bridge - lateral protuberance tract"
Comment This fascicle corresponds to the protocerebral bridge-lateral protuberance tract. The name was changed because the fascicle contains many fibers that are not derived from the protocerebral bridge and because the term protuberance is no longer used (Ito et al., 2014).
