It fasciculates with the posterior dorsal mesothoracic nerve, extends ventrally and medially, bifurcates and follows the main course of the pathway anteriorly, extending halfway along the prothoracic neuromere, and posteriorly, up to the bifurcation of the metathoracic crossbranch. The main crossbranch extends contralaterally. Occasionally, anterior and posterior crossbranches are observed. The central branches form mostly terminal but also en passant synapses. Presynaptic terminals are enriched near the midline, along the anterior branch, contralateral branches and on four stereotypic locations on the posterior projecting branch. sensory perception detection of mechanical stimulus bilateral
