  1. 1. Tactile Sensory Control of Dexterous Manipulation in Humans

    Författare :Ingvars Birznieks; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; cutaneous sensibility; tactile afferents; fingertip force; grasp stability; human hand; manipulation; object shape; precision grip; sensorimotor control; coding; Fysiologi; Physiology; Fysiologi; fysiologi; Physiology;

    Sammanfattning : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. LÄS MER

  3. 2. Measuring the tactile sense: Cortical mechanisms and clinical applications of tactile direction discrimination

    Författare :Linda Lundblad; Göteborgs universitet; []
    Nyckelord :AIC; diabetic neuropathy; DLPFC; fMRI; hairy skin; psychophysics; QST testing; somatosensory cortex; tactile direction discrimination;

    Sammanfattning : Most of the studies aiming to investigate the human tactile sense are done on the glabrous skin. Still, there is a need for a quantitative method for evaluating nervous function of the hairy skin. LÄS MER

  4. 3. The Perception and Evaluation of Pleasant Touch and the Development of "Satiety" for Hedonic Tactile Experiences

    Författare :Chantal Triscoli; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pleasant touch; CT afferents; Top-down mechanisms; Satiety; Liking; Wanting;

    Sammanfattning : Pleasant touch is a hedonic experience and one of the most powerful means for social bonding and for communicating affection. Touch similar to a human caress is detected by the “C tactile (CT) afferents”, a class of mechanoreceptors which respond preferentially to stroking velocities between 1 and 10 cm/s. LÄS MER

  5. 4. Physiological properties of unmyelinated low-threshold tactile (CT) afferents in the human hairy skin

    Författare :Katarina Wiklund Fernström; Göteborgs universitet; []
    Nyckelord :Human; microneurography; mechanoafferent; unmyelinated; sensory; touch; temperature; capsaicin;

    Sammanfattning : For more than a decade it has been known that human skin is supplied with a system of slowly conducting unmyelinated afferents that respond strongly to innocuous skin deformation (Nordin, 1990; Vallbo et al., 1993). LÄS MER

  7. 5. Affective touch throughout life: from cortical processing in infancy to touch perception in adulthood

    Författare :Emma H. Jönsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affective touch; Touch perception; Cortical activation; C-tactile afferents;

    Sammanfattning : Affective, interpersonal touch is important for forming and maintaining social bonds. In the hairy skin of humans there is a specific type of nerve fibers called C-tactile (CT) afferents which are optimally activated by a light stroking of the skin, like a caress. LÄS MER
