Orientation of the head during locomotion tasks with different accuracy demands. A: representative stick figures of one cat (BL) near left forelimb paw contact during simple and complex locomotion. The right side of the body is indicated by the continuous line and the left side, by the dashed line. The trajectory of the GCM is shown by a gray line. Dotted lines show the angle between the long head axis and the vertical. B: averaged head angles during simple and complex locomotion. SDs during simple locomotion exceeded head angle ranges depicted in the plot and therefore are shown for ladder-5 task only. C: intersection: averaged horizontal position of the intersection point between the ground and the head axis during different tasks. SDs were similar across all tasks and for clarity are shown only for simple locomotion. C: fore digits: horizontal displacement of the leading forelimb digits. Other designations as in Fig. 4.
