Frequency-Dependent Processing in the Vibrissa Sensory System [PDF]

Journal of Neurophysiology, 2004
The vibrissa sensory system is a key model for investigating principles of sensory processing. Specific frequency ranges of vibrissa motion, generated by rodent sensory behaviors (e.g., active exploration or resting) and by stimulus features, characterize perception by this system.

Morphological diversity of facial vibrissae in Chaetophractus vellerosus (Mammalia, Xenarthra, Dasypodidae) and differential mechanoperception

, 2020
Vibrissae are specialized and complex mechanoreceptor organs present in the skin of most mammals that respond to a diverse mechanical stimuli (e.g. tension, pressure, movement, vibrations) and provide information on distance to the object, its location ...

Consistency of Angular Tuning in the Rat Vibrissa System

Journal of Neurophysiology, 2010
Each region along the rat mystacial vibrissa pathway contains neurons that respond preferentially to vibrissa deflections in a particular direction, a property called angular tuning. Angular tuning is normally defined using responses to deflections of the principal vibrissa, which evokes the largest response magnitude.

Vibrissae and Genetic Background: Their Role in a Water Submersion Task with Mice

, 1967
Four experiments are reported which demonstrate that mice, deprived of their vibrissae and from different species and strains representing inbred, hybrid, and four-way cross genetic backgrounds, are impaired in their survival response on a water ...

Trps1^Δgt/Δgt vibrissae follicles exhibit increased levels of proliferation.

, 2012
(A,B) Keratin 14 staining (red) was consistent in the epithelial compartment of Trps1+/+ and Trps1Δgt/Δgt vibrissae follicles at E16.5. (C,D) Alkaline phosphatase staining (purple) revealed an intact dermal papilla and reduced collagen capsule ...

Structure and Function of Pinniped Vibrissae

, 2013
The vibrissal system of pinnipeds relies on sturdy, specialized vibrissae and supporting neural architecture apparently designed for the reception of waterborne disturbances.

Short‐term reorganization of input‐deprived motor vibrissae representation following motor disconnection in adult rats

, 2006
It has been proposed that abnormal vibrissae input to the motor cortex (M1) mediates short-term cortical reorganization after facial nerve lesion. To test this hypothesis, we cut first the infraorbital nerve (ION cut) and then the facial nerve (VII cut ...

Northern fur seal whisker bioaccumulation and partitioning of polybrominated diphenyl ethers and organochlorines

Emerging Contaminants
The eastern Pacific stock of northern fur seals (Callorhinus ursinus) on the Pribilof Islands, Alaska represents over 50 % of the global breeding population, but it has experienced population declines of unknown cause(s) since 1980.

Determination of the vibration sensitivity of harbour seal (Phoca vitulina) vibrissae

, 1984
Psychophysical techniques were employed to measure the sensitivity of the vibrissae of a harbour seal (Phoca vitulina) to sinusoidal vibrations ranging between 100 and 2500 hertz.

Do Innervation Patterns of Mystacial Vibrissae in Harbor Seals, Phoca Vitulina, Explain Specialization in Trail Following Behavior? [PDF]

, 2019
The microstructure of vibrissae, or whiskers, of terrestrial mammals has been well-studied, but the study of marine mammal vibrissae is relatively overlooked.
