AB  - During locomotion, animals employ visual and mechanical cues in
order to establish the orientation of their head, which reflects the
orientation of the visual coordinate system. However, in certain
situations, contradictory cues may suggest different orientations
relative to the environment. We recorded blowflies walking on a
horizontal or tilted surface surrounded by visual cues suggesting a
variety of orientations.We found that the different orientations relative
to gravity of visual cues and walking surface were integrated, with the
orientation of the surface being the major contributor to head
orientation, while visual cues and gravity also play an important
role. In contrast, visual cues did not affect body orientation much. Cue
integration was modeled as the weighted sum of orientations
suggested by the different cues. Our model suggests that in the
case of lacking visual cues, more weight is given to gravity.
