Application of Pinniped Vibrissae to Aeropropulsion [PDF]
Volume 2A: Turbomachinery, 2015 Vibrissae (whiskers) of Phoca Vitulina (Harbor Seal) and Mirounga Angustirostris (Elephant Seal) possess undulations along their length. Harbor Seal Vibrissae have been shown to reduce vortex induced vibrations and reduce drag compared to appropriately scaled cylinders and ellipses.

Non-homogeneous spatial configuration of vibrissae cortical representation in layer IV of the barrel somatosensory cortex [PDF]
Biological Research, 2008 In the present experiments we studied exclusive and overlapping cortical representational áreas of the vibrissae in layer IV cells, across the entire barrel subfield of the rat somatosensory cortex, looking for evidences that would challenge the present ...

An Artificial Vibrissa-Like Sensor for Detection of Flows [PDF]
Sensors, 2019 In nature, there are several examples of sophisticated sensory systems to sense flows, e.g., the vibrissae of mammals. Seals can detect the flow of their prey, and rats are able to perceive the flow of surrounding air.

Fused traditional and geometric morphometrics demonstrate pinniped whisker diversity. [PDF]
PLoS ONE, 2012 Vibrissae (whiskers) are important components of the mammalian tactile sensory system, and primarily function as detectors of vibrotactile information from the environment.

Muscle-Nerve-Nerve Grafting Improves Facial Reanimation in Rats Following Facial Nerve Injury
Frontiers in Neurology, 2021 Nerve injury resulting in muscle paralysis from trauma or surgery is a major medical problem. Repair of such injuries with existing nerve grafting and reconstructive techniques often results in less than optimal outcomes.

Vibrissae-Evoked Behavior and Conditioning before Functional Ontogeny of the Somatosensory Vibrissae Cortex [PDF]
The Journal of Neuroscience, 1999 The following experiments determined that the somatosensory whisker system is functional and capable of experience-dependent behavioral plasticity in the neonate before functional maturation of the somatosensory whisker cortex. First, unilateral whisker stimulation caused increased behavioral activity in both postnatal day (P) 3–4 and P8 pups, whereas ...

Gradient of tactile properties in the rat whisker pad.
PLoS Biology, 2020 The array of vibrissae on a rat's face is the first stage in a high-resolution tactile sensing system. Progressing from rostral to caudal in any vibrissae row results in an increase in whisker length and thickness. This may, in turn, provide a systematic

A penile spine/vibrissa enhancer sequence is missing in modern and extinct humans but is retained in multiple primates with penile spines and sensory vibrissae. [PDF]
PLoS ONE, 2013 Previous studies show that humans have a large genomic deletion downstream of the Androgen Receptor gene that eliminates an ancestral mammalian regulatory enhancer that drives expression in developing penile spines and sensory vibrissae.

A vibrissa pathway that activates the limbic system
eLife, 2021 ABSTRACT Vibrissa sensory inputs play a central role in driving rodent behavior. These inputs transit through the sensory trigeminal nuclei, which give rise to the ascending lemniscal and paralemniscal pathways. While lemniscal projections are somatotopically mapped from brain stem to cortex, those of the paralemniscal pathway are more ...

Role of the motor cortex in the generation of classically conditioned eyelid and vibrissae responses
Scientific Reports, 2021 The eyelid motor system has been used for years as an experimental model for studying the neuronal mechanisms underlying motor and cognitive learning, mainly with classical conditioning procedures. Nonetheless, it is not known yet which brain structures,
