Evidence for Functional Groupings of Vibrissae across the Rodent Mystacial Pad
Fig 6
Mappings between distance, yaw, and θimpact.
A. Values of θimpact mapped to yaw and distance for the 31 vibrissae of the left array at pitch = 0°. Resting-contacts are shown in black, while whisking-contacts are color coded according to θimpact. A yaw value of +90 means that the left whiskers were turned towards the wall, resulting in a large number of resting-contacts. A yaw value of -90 means that the left whiskers were turned away from the wall, resulting in no contacts (white). B. The difference between the number of left and right vibrissae (nL—nR) in contact with the surface is shown as a function of yaw and distance. Each color represents a different pitch value. This difference is seen to increase as the yaw increases, providing the rat with information about yaw.
