Development of computational and experimental tools to study mechanotransduction in C.elegans and primates
… in the skin tissue. These nerve endings, called mechanoreceptors, transduce the mechanical signals to generate a neural code of the incident stimuli enabling us to feel the object. The neural codes, generated by the spatial distribution of responding mechanoreceptors, are in the form of a …

Tactile sensing of shape : biomechanics of contact investigated using imaging and modeling
… pertains to human tactile sense. During touch, mechanoreceptors beneath the skin surface are mechanically loaded due to physical contact of the skin with an object and respond with a series of neural impulses. This neural population response is decoded by the central nervous system to result in …

Modulation of mechanosensitive gastro-oesophageal vagal afferents by novel targets.
… of signals from peripheral vagal afferent mechanoreceptors to the central nervous system has been identified as the most accessible target for control of neuronal pathways and reflexes central to gastrointestinal disorders such as GORD, disordered food intake and functional dyspepsia. There …

Tactile sensor design optimization for footwear applications from piezoresistive elastomer to Hall-effect integrated sensing methods
… environment. Understanding how to best replicate mechanoreceptors in feet can lead to major improvements in plantar sensing for athletic performance analysis and medical devices. However, current plantar sensing technologies are unable to meet the associated demands for accuracy, sensitivity, and …

The effect of neck muscle fatigue on shoulder humeral rotation proprioception
… to disrupt afferent feedback from postural mechanoreceptors as it has been observed to cause decrements in upper limb proprioceptive accuracy. There has been limited research to quantify this interaction at the shoulder; thus further investigation into the effect of neck fatigue on shoulder …

Influence of Vibratory Plantar Stimulation on Cortical Motor Planning and Spatiotemporal Step Parameters
… supports movement preparation, while plantar mechanoreceptors provide essential input for anticipatory postural adjustments and gait initiation. Although previous literature suggests that plantar vibratory stimulation can improve balance and reduce gait variability, its influence on cortical …

Mechanosensory structures in the beaks of probe-foraging birds in relation to their foraging ecology
… that facilitates remote-touch is made up of mechanoreceptors housed in dense clusters of foramina in the distal portions of the beak bones (each unit of foramen and associated receptors is referred to as a “sensory pit”). Previous research showed that in ibises (Family: Threskiornithidae), …

Otolith morphologies in the genus sinocyclocheilus
… including the increase in size and number of mechanoreceptors. Sinocyclocheilus are hearing specialists, and it is possible that cave species of this genus have increased reliance on hearing when compared to their surface-living relatives. The central hypothesis that motivates this work is …

Evaluation of the role of odontoblasts in dental pain
… the dentine fluid, which are detected through mechanoreceptors on dental sensory neurons. However, initial studies have identified tentative links between TRP channels and dental pain, suggesting that TRP channels in dental nociceptive neurons may be directly activated by temperature changes …

Minimally invasive neuromodulation using mechanically-sensitive ion channels and magnetically-actuated nanotransducers
… observed neuromodulatory effects for a gamut of mechanoreceptors and stimulation conditions. Calcium imaging results demonstrate that this method of nanotransducer targeting can elicit neuronal responses at 40mT even via endogenous ion channels, and that greater amplitudes of response can be …

Mechanisms of thermal sensitivity in rodent primary afferent neurons innervating the skin
… sensitivity in a proportion of low threshold mechanoreceptors and increased the cold responses in a proportion of cold sensitive A and C fibre nociceptors. Interestingly 4-AP or TEA had no effect on the cold responses of innocuous cold thermoreceptors. Drug induced cold sensitivity was …

bio-inspired attitude control of micro air vehicles using rich information from airflow sensors
… biologists found that birds and bats use their mechanoreceptors to sense the airflow information and use this information directly to achieve their agile flight performance. Inspired by this phenomenon, an attitude control system for micro air vehicles using rich amount of airflow sensor …

Assessment of Proprioceptive Acuity in Patients with Stroke with Left Hemiplegia Compared to Healthy Controls
Proprioceptive information from mechanoreceptors within muscles, tendons, and skin, gives rise to kinesthesia and the sense of joint position. This information is not only crucial for bodily awareness, but it also impacts voluntary motor control, the maintenance of muscle tone and posture. Cortical …

Investigating the Illusion of Wetness: Cold Dry Stimuli in Sensory Perception
… pressure that are sensed by thermoreceptors and mechanoreceptors in the skin. In addition to perceiving the wetness of damp fabrics in contact with the skin or the presence of sweat on the skin, humans can perceive wetness in the absence of any moisture, a phenomenon known as illusory wetness. …

Proprioceptive acuity in patients with a torn anterior cruciate ligament following a rehabilitation programme
… in turn hasbeen credited to disruption of the mechanoreceptors. Although several studies show thatproprioception is improved by neuromuscular training, most studies use the contra-laterallimb as a control, which raises the question of whether there may be a pre-disposingproprioceptive deficit …

Developmental And Signaling Mechanisms Of Touch Neurons
… are conveyed by cutaneous low-threshold mechanoreceptors (LTMRs), which convey innocuous tactile sensations to local spinal circuits and to regions of the brain through direct connections. However, under pathological conditions, these neurons can aberrantly activate noxious pain …

Evidence for the Sensory Receptor(s) of the Mounting Sex Pheromone in Two Species of Ixodid Ticks, <i>Dermacentor variabilis</i> (Say) and <i>Dermacentor andersoni</i> Stiles
… while the ventral pair are strictly mechanoreceptors. The dorsal and middle sensory setae exhibit a single pore-like structure located at their tip, a feature characteristic of gustatory or mechanogustatory sensilla similar to those found on the palps that are believed to function as …

Liquid crystal thermography in neuropathic assessment of the diabetic foot.
