Our confocal three‐dimensional analyses revealed substantial differences in the innervation to vibrissal follicle‐sinus complexes (FSCs) in the rat and cat. This is the first study using anti‐protein gene product 9.5 (PGP9.5) immunolabeling and confocal microscopy on thick sections to examine systematically the terminal arborizations of the various FSC endings and to compare them between two species, the rat and the cat, that have similar‐appearing FSCs but different exploratory behaviors, such… 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
Microstructure and innervation of the mystacial vibrissal follicle-sinus complex in bearded seals, Erignathus barbatus (Pinnipedia: Phocidae).
TLDR
The premise that pinniped vibrissae are sensitive active-touch receptor systems, and that structural differences in bearded seals, relative to other phocids, may be adaptations for benthic foraging adaptations, is supported. Expand
Adaptations in the structure and innervation of follicle‐sinus complexes to an aquatic environment as seen in the Florida manatee (Trichechus manatus latirostris)
TLDR
The largest perioral vibrissae, which are used for grasping, have exceptionally well‐developed medullary cores that have a structure and dense small‐fiber innervation resembling that of tooth pulp, which differ from that seen in terrestrial mammals. Expand
Structure-function correlations of rat trigeminal primary neurons: Emphasis on club-like endings, a vibrissal mechanoreceptor
This study focuses on the structure and function of the primary sensory neurons that innervate vibrissal follicles in the rat. Both the peripheral and central terminations, as well as their firingExpand
How many hair follicles are innervated by one afferent axon? A confocal microscopic analysis of palisade endings in the auricular skin of thy1-YFP transgenic mouse
TLDR
In this study, innervation of the palisade endings was investigated in the auricular skin of thy1-YFP transgenic mouse to find out how their original primary neurons make up a part of the ending. Expand

This study focuses on the structure and function of the primary sensory neurons that innervate vibrissal follicles in the rat. Both the peripheral and central terminations, as well as their firingExpand
Confocal Microscopic Analysis of Merkel Innervation in the Cat Mystacial Vibrissa Follicles
Three-dimensional morphology of the Merkel innervation in very thick sections of the cat mystacial vibrissa follicles as well as in whole mounted tissues were demonstrated by using a confocal laserExpand
The Morphology of the Rat Vibrissal Follicle-Sinus Complex Revealed by Three-Dimensional Computer-Aided Reconstruction
TLDR
This study has demonstrated the previously underappreciated 3-dimensional structure of the vibrissal FSC, which differs from previously reported descriptions, and provides data that will enhance the understanding of vibrISSal function. Expand
The follicle‐sinus complex of the bottlenose dolphin (Tursiops truncatus). Functional anatomy and possible evolutional significance of its somato‐sensory innervation
TLDR
The FSC of the bottlenose dolphin possesses a rich somatomotor innervation and a set of peptidergic visceromotor fibers, which suggests a mechanoreceptor function in the newborns, possibly finalized to search for the opening of the mother's nipples. Expand
Elaboration and Innervation of the Vibrissal System in the Rock Hyrax (Procavia capensis)
TLDR
The possibility that hyraxes, like manatees, are tactile specialists with vibrissae that cover the entire postfacial body is investigated, indicating that this distribution may represent the ancestral condition for the supraorder Paenungulata. Expand

The innervation of the mystacial pad in the adult rat studied by anterograde transport of HRP conjugates
TLDR
The results reveal that the innervation of the mystacial pad especially by fine-caliber axons is far more extensive and complex than previously described. 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
Comprehensive immunofluorescence and lectin binding analysis of vibrissal follicle sinus complex innervation in the mystacial pad of the rat
TLDR
The innervation of the vibrissal follicle sinus complexes in the mystacial pad of the rat was examined and some previous hypotheses about biochemical and morphological relationships between peripheral innervation and sensory ganglion cells are refuted. 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
A comparative light microscopic analysis of the sensory innervation of the mystacial pad. I. Innervation of vibrissal follicle‐sinus complexes
TLDR
This comparative study was conducted 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. Expand
The innervation of the mystacial pad of the rat as revealed by PGP 9.5 immunofluorescence
TLDR
The innervation of the mystacial pad in the rat was investigated with the aid of antihuman protein gene product (PGP) 9.5 immunofluorescence, which revealed all previously known innervation as well as a wide variety of small‐caliber axons and some endings of large‐caliber afferents that had not been observed before.

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
