Hairs and vibrissae in the Rhinocerotidae
Journal of Zoology, 1969Evidence is reviewed and observations are submitted concerning the occurrence and distribution of body hair in rhinoceroses. Absence of externally visible hair is shown to be not necessarily indicative of absence of hair follicles and to be part of a morphological cooling mechanism necessitated by the dynamics of the large body.

What's on the vibrissa abscissa?
Journal of Experimental Biology, 2016![Graphic][1] The face of a rat is peppered with stiff, conical hairs called vibrissae, more commonly known as whiskers. As nocturnal animals that live in dingy, cramped hovels, rats rely on tactile information from their whiskers to get through the night.

The role of vibrissae in behavior: A status review
Veterinary Research Communications, 1986Vibrissae or tactile hairs are an important part of the tactile sensory apparatus of many mammals. A wide range of suggested functions found in the literature include food acquisition, prey attack, aggression and attack behavior, facial expression in intraspecies communications, dispersion of pheromones, maintaining head position in swimming, and a ...

Finite degree-of-freedom models for animal vibrissae
2009 European Control Conference (ECC), 2009The reception of vibrations is a special sense of touch, important for many insects and vertebrata. The latter realize this reception by means of hair-shaped vibrissae. Disregarding different types of such sensors we set up a principal mechanical model to describe their modes of operation (passive and active vibrissae).

The sensory contribution of a single vibrissa's cortical barrel
Journal of Neurophysiology, 1986The sensory contribution of the cortex containing the cortical barrel of the C1 vibrissa was studied in rats using the ablation-behavior method. Three independent experiments were performed, each requiring stimulus transduction by the C1 vibrissa but varying in their perceptual demands.

The growth of vibrissa dermal papilla cells in vitro
British Journal of Dermatology, 1981SUMMARY Vibrissa dermal papilla cells have been successfully grown and serially cultured and their early behaviour compared with cultured feather dermal papillae. Initially the vibrissa cells demonstrated singular characteristics, including poor spreading ability, before eventually forming a fibroblast-like population of cells.

The multipotency of adult vibrissa follicle stem cells
Differentiation, 2009Several studies focused on the characterization of bulge keratinocytes have proved that they are multipotent stem cells, being recruited not only to regenerate the hair follicle itself, but also the sebaceous gland and the epidermis. However, due to the difficulty in preparing transplantable cell sheets harvested with conventional enzymatic digestion ...

Plasticity and the Mystacial Vibrissae of Rodents
1991The neural pathway linking the mystacial vibrissae of rats and mice with the face region of the contralateral SI cerebral cortex has been used more extensively for studying the plasticity of neural connections than any other part of the somatosensory system. To the experimenter this system offers three unique advantages.

Innervation of a single vibrissa in the whisker-pad of rats
NeuroReport, 2000Innervation of the gamma straddler vibrissa and distribution of individual gamma vibrissal sensory nerve fibers within infraorbital nerve branches were investigated in adult rats. In the close vicinity (2 mm) of the whisker-pad, one-fifth of the nerve fibers innervating the gamma vibrissa were still located in nerves to neighboring (beta, delta, C1 and

Effect of castration and testosterone propionate on mouse vibrissae
British Journal of Dermatology, 1983Vibrissae of normal mice were measured for six cycles starting at birth. Groups of immature male albino mice were castrated at 21 days of age when E, F, G and H (Danforth nomenclature, 1925) vibrissae were in their first cycle of growth. Levels of testosterone in their peripheral plasma were reduced to about one tenth of the normal.
