Two laterally projecting neurites that originate in the ventral esophagus arborize in the ventrolateral protocerebrum, antennal nerve, the subesophageal ganglion and the antennal motor and mechanosensory center. A pair of descending axons project from the ventral esophagus into the cervical connective (Busch et al., 2009).
