(2018), but does not exactly correspond to Power's (1948) tectulum (FBbt:00007727). Originally named 'upper tectulum', as this was the upper of two 'tectulum' layers in Namiki et al. (2018), but this region is the intermediate layer of Court et al. (2020). IntTct VFB:FBbt_00047519 tectulum FBbt:00047519 fly_anatomy.ontology Adult neuropil region spanning the three thoracic neuromeres, ventral to the neck, wing and haltere neuropils of the upper tectulum and dorsal to the lower tectulum (Namiki et al., 2018; Court et al., 2020). It extends from the prothoracic medial ventral association center to the posterior margin of the mesothoracic neuromere at the commissure of fine fibers (Court et al., 2020). tectulum subdivision adult prothoracic neuromere adult mesothoracic neuromere adult metathoracic neuromere
