  2. 1. Somatosensory Circuits in the Central Nervous System

    Author : Hannah M. Weman; Malin C. Lagerström; Sarah E. Ross; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glycine receptor alpha 3; urocortin 3; vesicular monoaminergic transporter 2; nociception; pruriception; spinal cord; somatosensory cortex; DREADD; rabies tracing; transcriptomics; Neuroscience; Neurovetenskap;

    Abstract : Spinal glycinergic neurons prevent spontaneous sensations of pain and itch, and development of persistent pain and itch conditions. The glycine receptor alpha 3 subunit (GLRA3) is suggested to be involved in certain inflammatory models, but not in acute nociception. READ MORE

  4. 2. Affective touch throughout life: from cortical processing in infancy to touch perception in adulthood

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

    Abstract : 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. READ MORE

  5. 3. Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis

    Author : Elin Eriksson Hagberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aβ afferent; C-tactile; touch; EEG; MEG; SEEG;

    Abstract : The present work summarizes investigations of the temporal correlates of brain activity elicited by gentle, moving touch on the hairy skin in healthy participants and in epilepsy patients. Light touch to the hairy skin activates two distinct afferent classes: fast conducting, Aβ afferents and slowly conducting C-tactile (CT) afferents. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Hedonic, neural, and autonomic responses to prolonged gentle touch

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

    Abstract : 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). READ MORE
