All angular positions are represented in degrees relative to the rostral-caudal axis, with θ = 0° pointing caudal and θ = 180° pointing rostral. Column 1: The identity of the whisker. Column 2: The angle θ_FR is the angular position at which the whisker is fully retracted against the head. Any further retraction would cause a portion of the whisker to penetrate the head. Column 3: The angle θ_rest is the angular position of biomechanical rest. This is the angular position of the whiskers when none of the facial muscles are contracted. Column 4: The angle θ_FP is the angular position at which the whisker is fully protracted in the large-amplitude simulations. Column 5: The magnitude of the angular difference between the maximum retracted position and the whisker’s resting position. The mappings corresponding to this range are shown in Fig 15B. Column 6: Protraction amplitudes (θ_protraction) for simulations in which the central and caudal vibrissae were allowed to move through larger angles than the rostral-most vibrissae. The mappings corresponding to this range are shown in Fig 15C. Column 7: The full angular range covered, from θ_FR to θ_FP.
