Fig 8. Vibrissae in exterior rows constrain values of relative pitch.
A. Vibrissae of the A-row show a relationship between θimpact, pitch, and distance that are close to a mirror image of the mappings for the D and E row vibrissae. Mappings for the E row are not shown, but Fig 7 shows they will closely resemble the mappings of the D row. B. Overlaying the mappings for dorsal and ventral vibrissae constrains the possible values of head pitch. The mappings of both (A) and (B) are shown for a value of yaw = 0°, but similar results were found for all values of yaw. As in all previous figures, resting-contacts are shown in black, while whisking-contacts are color coded according to θimpact.
