This comparative study was conducted (1) to provide a detailed, comprehensive description of the innervation to the follicle‐sinus complex (F‐SC) of mystacial vibrissae and (2) to determine if interspecies variability in the innervation of the F‐SCs may be related to differences in the structure or existence of barrels in the primary somatosensory (SI) cortex. Two silver techniques (Winkelmann on 100μm‐thick‐frozen sections and Sevier‐Munger on 8μ‐thick paraffin sections) were applied to… Expand
A comparative light microscopic analysis of the sensory innervation of the mystacial pad. II. The common fur between the vibrissae
TLDR
The innervation to the common fur between the vibrissae was examined in the hamster, mouse, rat, gerbil, rabbit, guinea pig, and cat to find major unpredictable species‐related variations in the distribution of receptor types, innervation density, and the quantity of innervation in the skin between neighboring vibrISSae.

Structure and innervation of the vibrissal follicle‐sinus complex in the Australian water rat, Hydromys chrysogaster
TLDR
Structural specializations of the water rat F‐SC are discussed as an analogous development in mammals adapted to the aquatic environment, primarily in terms of thermoregulation, whereas its high degree of innervation is assessed to lend support to the hypothesis that the vibrissal system is of special significance in aquatic mammals. Expand
Dual innervation of the rat vibrissa: Responses of trigeminal ganglion cells projecting through deep or superficial nerves
TLDR
Anatomical and electrophysiological methods were used to determine if DVN and SVN fibers have differing response profiles and to test the hypothesis that they form part of a diffuse, multivibrissal system. Expand
Innervation of nonmystacial vibrissae in the adult rat
TLDR
Though there was no correlation between ICB innervation and whisking, the regional variations in F‐SC innervation suggest that functional differences may exist between vibrissae at different locations in the body. Expand
Structure, vascularization, and innervation of the mystacial pad of the rat as revealed by the lectin griffonia simplicifolia
  • F. Rice

  • The Journal of comparative neurology
  • 1993
TLDR
The mystacial pad of the rat is endowed with rows of vibrissal follicle‐sinus complexes that receive a dense and rich variety of innervation, much of which is C fibers, and the peripheral distribution of the afferents that bind GSA I‐B4 mystacial pads was determined. Expand
Innervation of a single vibrissa in the whisker‐pad of rats
TLDR
Innervation of the γ straddler vibrissa and distribution of individual γ vibrissal sensory nerve fibers within infraorbital nerve branches were investigated in adult rats and convergence of γ vibrations to single vibrissa from neighboring nerves is suggested to be a consequence of overlapping vibrISSal representation in the Gasserian ganglion. Expand
Different distributions of the sensory and autonomic innervation among the microvasculature of the rat mystacial pad
TLDR
The perivascular innervation in the mystacial pad of the rat was characterized based upon immunochemical and lectin binding characteristics and distribution, suggesting that separate neuronal mechanisms may be involved in regulating the blood flow to different types of targets even within the confines of a small territory of tissue. Expand
Sequential differentiation of sensory innervation in the mystacial pad of the ferret
TLDR
In the ferret, innervation is virtually lacking in one target—the inner conical body of the F‐SCs, which is densely innervated in the rat, due to a failure of innervation to develop rather than to a secondary elimination of a transient innervation. Expand
Innervation of the maxillary vibrissae in mice as revealed by anterograde and retrograde tract tracing
TLDR
Indocarbocyanine dyes and confocal microscopy were combined to study the innervation of the mystacial vibrissae and vibrissa-specific sensory neuron distribution in the maxillary portion of the trigeminal ganglion of the mouse, revealing denser terminal receptor endings in a different distribution pattern than previously demonstrated in studies using the rat. Expand
Similarities and differences in the innervation of mystacial vibrissal follicle–sinus complexes in the rat and cat: A confocal microscopic study
TLDR
Although the basic structure of the FSCs is similar in the rat and cat, the numerous differences in innervation suggest that these species would have different tactile capabilities and perceptions possibly related to their different vibrissa‐related exploratory behaviors. Expand

TLDR
Identifying the Ruffini complex of the inner conical body and the FNEs of the dense connective tissue below the Ringwulst provide an anatomic explanation for physiological recordings of mystacial primary afferents with slowly adapting type II properties in the rat. Expand
Successive waves of differentiation of cutaneous afferents in rat mystacial skin
TLDR
These maturational changes in peripheral sensory innervation correlate with gradual changes in the structure of barrels in the first somatosensory cortex of postnatal rats. Expand
Development of order in the rat trigeminal system
TLDR
The present study details the development of the trigeminal nerve, its intrinsic organization, and its relationship with its peripheral and central targets, and provides evidence that the discrete brainstem pattern reflecting vibrissae distribution develops after organization is detectable in the nerve.

The ultrastructure and innervation of rat vibrissae
TLDR
The innervation of rat vibrissae has been studied by light and electron microscopy and the neurite‐Merkel cell complex is interpreted as representing a mechanoreceptor. Expand

TLDR
Striated muscles of the mystacial region of the common albino mouse have been described and it is proposed that these bands become stretched during the protraction of vibrissae and contract, by their elasticity, immediately upon the end of the follicular muscles' contraction, executing the fast return of vibrations to their resting, retracted position.

Projections of the common fur of the muzzle upon the cortical area for mystacial vibrissae in rats dewhiskered since birth
TLDR
It is shown that in the absence of the vibrissae since birth, the vibrissa area, and this alone, is invaded by projections from the contralateral fur (damaged side). Expand

The structural features of sinus hair follicles in Sorex unguiculatus were studied by macroscopic dissection, serial section light microscopy and electron microscopy to find the follicle is more specialized as a vibrating system than in other mammals. Expand
