1. 6. 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

3. 7. Upper extremity disability after stroke. Psychometric properties of outcome measures and perceived ability to perform daily hand activities

   Sammanfattning : Disability of the upper extremity is common after stroke. To be able to evaluate recovery and effects of interventions there is a need for stable and precise outcome measures. In order to design and target efficient rehabilitation interventions it is important to know which factors that affect the ability to perform daily hand activities. LÄS MER

4. 8. Hedonic, neural, and autonomic responses to prolonged gentle touch

   Författare :Chantal Triscoli; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; long-lasting touch; CT afferents; pleasantness; liking; wanting; satiety; orbitofrontal cortex; reward; heart rate variability;

   Sammanfattning : Physical contact among individuals, such as caressing and cuddling, is connoted by a strong emotional value, and is usually perceived as a pleasant and rewarding experience. C tactile (CT) afferents are a class of fibres that are specific channels for detecting touch at a caress-like veloc-ity (between 1 and 10 cm/s). LÄS MER

5. 9. Expressing emotions through vibration for perception and control

   Sammanfattning : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. LÄS MER

7. 10. Pain influences somatosensory perception : an experimental and clinical study

   Författare :Ann-Sofie Leffler; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Muscle pain; referred pain; hypoaesthesia; allodynia; musculoskeletal; pain; sensory abnormality; quantitative sensory testing; trapezius myalgia; somatosensory perception; perception thresholds; diffuse noxious inhibitory controls DNIC ; central hyperexcitability; tourniquet test; cold-pressor test.;

   Sammanfattning : The underlying mechanisms maintaining long-term pain localised to musculoskeletal structures and joints are not infrequently unknown. In routine clinical work with such patients insufficient attention has been paid to phenomena indicating altered excitability of the central nervous system (CNS). LÄS MER
