General Information
Term lower tectulum ID (Ontology) FBbt:00047174 (Fly Anatomy)
Definition Ventralmost layer of the tectulum that extends posteriorly 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). It is bordered ventrally by the ventral median tract of ventral cervical fasciculus and laterally by the dorsal lateral tract of ventral cervical fasciculus (Court et al., 2020).[ FlyBase:FBrf0239335 FlyBase:FBrf0246815 ]
Also Known As "LTct"
Comment The neuropil referred to as ovoid in Namiki et al. (2018) supplementary file 1 has an identical innervation profile to lower tectulum in Figure 5, so I have added this as a synonym - https://orcid.org/0000-0002-1373-1705.
