The rat vibrissal (whisker) system is an increasingly important model for the study of the sense of touch. This paper describes recent results obtained from high-speed videography of rat exploratory behavior and from modeling studies of vibrissal biomechanics. We review several features of vibrissal touch, including the mechanics of contact versus noncontact whisking, the coordination between head and whisker movements, and the use of information obtained from the whiskers to detect, localize… CONTINUE READING
