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). intermediate tract of dorsal cervical fasciculus - haltere commissure intermediate tract of dorsal cervical fasciculus - commissure of fine fibers haltere tract adult prothoracic neuromere adult mesothoracic neuromere
