Evidence for Functional Groupings of Vibrissae across the Rodent Mystacial Pad
Fig 18
Head pitch, intrinsic curvature, and implications for simulation patterns.
A. The intrinsic curvature for each vibrissa is shown relative to the head at a level pitch (left), the head pitched down (middle), and the head pitched up (right). Gray traces correspond to the direction of intrinsic curvature at rest and black corresponds to the direction of intrinsic curvature after a protraction of 60°. B. In a burrow most of the vibrissae are in resting contact with a surface, but the force exerted by the surface on the whiskers is in different directions for different rows.
