Responses of a locust visual interneuron correlate with simple and compound object motion within the vertical plane.

ABSTRACT: Animals living in complex visual environments must contend with multiple visual cues that signal potential threats by detecting approaching objects and generating adaptive avoidance responses. One collision detection system in locusts is composed of the lobula giant movement detector (LGMD) and its postsynaptic partner, the descending contralateral movement detector (DCMD). Extensive work on this pathway has revealed that it is preferentially selective to visual stimuli generated by an approaching object (looming) and triggers avoidance behaviours such as jumping and flight steering. Recent work has shown that this pathway also responds characteristically to complex object motion that includes trajectory changes in the horizontal plane. To test the hypothesis that responses of this pathway
