All four neurons exit the brain via the antennal nerve, which is close to their soma location, and follow it to the frontal nerve junction before taking different routes (Shimada-Niwa and Niwa, 2014). One projects anteriorly to the pharyngeal muscle, the other three innervate the prothoracic gland and the proventriculus (Shimada-Niwa and Niwa, 2014). FBbt:00111310
