intermediate tract of dorsal cervical fasciculus

ID: FBbt_00047534

Intermediate continuation of fibers from the dorsal cervical fascicle into the adult ventral nerve cord (Power, 1948. It runs dorsally through the prothoracic and mesothoracic neuromeres (Power, 1948. Towards the posterior, it becomes subdivided into two separate tracts, with the inner tract turning abruptly medially to form the commissure of fine fibers of the ITD in the mesothoracic neuromere (Power, 1948. The larger, more lateral subdivision splits again more posteriorly, with fibers of the lateral division entering the dorsal metathoracic (haltere) nerve (via the haltere tract) and fibers of the medial division entering the metathoracic anterior intermediate (haltere) commissure (Power, 1948; Court et al., 2020. (Power, 1948, Court et al., 2020, Boerner and Duch, 2010, Namiki et al., 2018)

Court et al., 2020 refer to the medial subdivision (ITD-CFF) of this tract as being the new ITD, but do not provide a replacement name for this combined tract.
