Abstract:		"Sex pheromones orient male moths toward conspecific female moths; the presence of visual information modulates this behavior. In the current study, we explore candidate neuronal pathways for the interaction between vision and the locomotor signal for pheromone orientation. We describe the connectivity between visual neuropils and brain premotor centers, the posterior slope (PS) and the lateral accessory lobe (LAL), in the silkmoth Bombyx mori. Using a single-cell labeling technique, we analyze visual projection neurons supplying these areas. Neurons from both the medulla and lobula complex projected to the PS but only the neurons originating in the lobula complex had additional processes to the LAL. Further, we identified populations of putative feedback neurons from the premotor centers to the optic lobe. Neurons originating in the PS were likely to project to the medulla, whereas those originating in the LAL were likely to project to the lobula complex. The anatomical study contributes to further understanding of integration of visual information on the locomotor control in the insect brain"
