Animals respond to numerous biologically relevant environmental stimuli by performing various behaviours. Organisms such as locusts swarm during unfavorable conditions in complex, dynamic visual environments that requires collision detection systems to successfully orient themselves amongst stationary objects and conspecifics to avoid threats such as an approaching predator. Locusts (Locusta migratoria) and their visual motion-detection pathway, comprised of the lobula giant movement detector (LGMD) and the descending contralateral movement detector (DCMD), responds selectively to objects approaching on a direct collision course. We presented the locusts with biologically relevant stimuli of 3D objects with trajectory changes along the vertical plane. We have found that stimulus that change in trajectory in the vertical plane is consistent with objects that change in trajectory along the horizontal plane. Data shows that there is a slight delay in firing in the motion-detection pathway after the stimulus changes trajectory. This allows us to infer that there is a generalized system within the locust to recognize approaching objects regardless of its origin. Although insects may have less complex neural systems than mammals they are highly capable of processing elaborate visual cues to navigate and orient themselves in their natural environment.
