The Relationship Between Somatosensory Processing and Handwriting Proficiency
… aspect of sensory processing for penmanship is somatosensation. The contribution of somatosensory processing to handwriting proficiency has not been adequately researched. Therefore, this study evaluated the contribution of somatosensory processing to handwriting proficiency. Seventy-four …

Graded lines: using genetic variation in neuronal projections to understand functional organization
… as vision, navigation, motor control and somatosensation showed a similar variation in gene expression, which was functionally relevant. This establishes a common reference frame for diverse modalities of cognition. Secondly, I began an ongoing investigation of the signals that motor …

Effects of Neck Muscle Fatigue on the Vestibulo-Ocular Reflex
… the literature, contribution of cervical spine somatosensation on visual stability is not fully understood. The overall aim of the present work was to investigate whether impaired somatosensory information from the cervical spine, caused by neck muscle fatigue, directly influences dynamic visual …

Slow Touch and Fast Nociception: Exploration of the Interactions Between Noxious and Innocuous Mechanical Touch Sensation
Human cutaneous somatosensation is a multimodal physiological process by which physical stimuli on the body surface activate neural substrates that consequently give rise to perceptions such as pressure/vibration, temperature, itch, and pain. When considering skin mechanosensation, the canonical …

Mechanisms for Inactivation in Piezo Ion Channels
… In vertebrates, the molecular mechanisms of somatosensation has remained an important and unresolved neurobiological question. In the past decade, Piezo ion channels have emerged as the first vertebrate ion channels identified responsible for transforming somatosensory stimuli into excitatory …

The Effect of Subthreshold Vibration on Lateral Reactive Balance
… that display worsened balance from decreased somatosensation

Soaking Sensual Nakedness: Haptic Bathhouse Explorations
… encounters will remind us of our wonderful somatosensation. How we feel during these sensual unions will add vividness to our lives and a desire to again search for more tactile stimuli feeding our rejuvenated mindfulness.

Quantifying gait stability based on body segment coordination relationships measured with wireless sensors
… measured through postural response latencies and somatosensation thresholds. Clinical disability and mobility were measured by self-report fall history and clinical questionnaires. In Aim 3, GSI cutoff values and amount of overground walking needed to separate MS fallers from MS non-fallers were …

Foot, ankle and lower limb somatosensory dysfunction in stroke
… oriented measures that assess higher-level somatosensation is encouraged.

Sensorimotor Recovery, Functional and Structural Brain Plasticity, and the Development of Chronic Pain Following Upper Limb Peripheral Nerve Transection and Microsurgical Repair
… in brain regions involved in pain perception and somatosensation. These results provide insight into peripheral regeneration, the development of chronic pain, brain plasticity and structure-function-behavioural relationships following nerve injury and have important therapeutic implications.

Force-Myography Based Estimation of Energy Absorption Capabilities of the Human Arm for Robotic Tele-Rehabilitation Therapy
… total loss of kinesthesia, proprioception, and somatosensation. Telerobotic therapy should be safe and easy to perform by therapists and patients, and this remote interaction must be realistic enough for therapy to work. Hence, a proper control system needs to be developed. Some controllers have …

Postural control and adaptation to threats to balance stability
… was dependant on ones own mechanoreceptive somatosensation and availability of visual information. Decreasing attention and alertness through sleep deprivation decreased adaptive capabilities, suggesting an important role for sleep in memory and consolidation of a new motor skill.

Somatosensory Involvement in the Conceptual Representation of Objects
… of objects. Interestingly, however, although somatosensation provides the first means of acquiring information from our environments and thus is integral to the development of conceptual representation, research has generally focused on motor system contributions to object processing. …

Molecular Mechanisms of Itch Sensations
… neuronal circuits. However, itch is a distinct somatosensation and has opposite characteristics to pain. Itch elicits scratching but pain causes withdrawal reflex. Interestingly, minor pain induced by scratching reduces itch and suppression of pain by opioid analgesics such as morphine elicits …

Modulation of synaptic transmission by TRP channels
… like hippocampus that are not tightly linked to somatosensation. In this study, I first determined the functionality of TRP channels at the first sensory synapse and hippocampus using pharmacological activators. I then determined if putatively endogenous TRP channel activators modulate synaptic …

ms-Scale temporal coding in the thalamus predicted by whisker dispersive vibrational transduction
Whether stimulus information is encoded in the whisker system has been a question of debate. Considering the remarkable temporal precision in the whisker system with spike timing as small as 10μs, there is potential for ultrahigh capacity information channel in kb/s. To study temporal structures in …

Sound-to-Touch Sensory Substitution and Beyond
Deafness affects an estimated 2 million people in the United States and 53 million worldwide. Cochlear implants are an effective therapeutic solution but suffer from a number of drawbacks: they are expensive, require an invasive surgery, have low efficacy in early-onset deaf adults, and not …

Cross-Modal Projections from Auditory to Visual Cortices in the Ferret
Recent studies have shown that neuronal connections occur between primary auditory and visual cortices of the primate (Falchier et al., 2002; Rockland and Ojima, 2003), and it has been suggested that these projections are involved in multisensory processing in these lower-level, core areas of …

Unique Features and Neuronal Properties in a Multisensory Cortex
UNIQUE FEAUTRES OF ORGANIZATION AND NEURONAL PROPERTIES IN A MULTISENSORY CORTEX Multisensory processing is a ubiquitous sensory effect that underlies a wide variety of behaviors, such as detection and orientation, as well as perceptual phenomena from speech comprehension to binding. Such …
