A good example of this is the fact that the male drosophila's lateral horn is 1% larger than females of the same species. The male lateral horn has abundant connections with the projecting neurons that come from the DA1, VA1lm and VL2a glomeruli of the antenal lobe (all of which are also larger in males). Each of these glomeruli are associated with the specific olfactory neurons that pick up pheromones. In moths the male-specific projecting pheromone-processing neurons innervate with glomeruli outside of the macroglomerular complex of the antennal lobe. Other studies in drosophila found that it is not just the neurons responsible for incoming information that are sexually dimorphic but also the lateral horn neurons that are sending information to the rest of the fly. The lateral horn neurons that synapse with the ventral nerve cord are dimorphic in their structure and respond to the drosophila sex pheromone cVA.
