Figure 6. Examples of the six elementary modes of fly locomotor behavior.
A) Fixed-front-on-Straight-Path (‘A’), B) Rotation-on-Straight-Path (‘B’), C) Fixated-Front-on-Curved-Path (‘C’), D) Rotation-on-Curved-Path (‘D’), E) Lingering (‘L’) and F) Rotation-in-place (‘R’). Quiver plots: blue lines represent the path traced by the mouse centre. The arrows represent the orientation of the fly's body axis.
