  2. 11. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference

    Author : Karin Rylander; Göteborgs universitet; []
    Keywords : CT afferent; thin fibre; autonomic; insula; fMRI;

    Abstract : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. READ MORE

  4. 12. Functional organisation and population behaviour of human peripheral nerve fibres : a microneurography study

    Author : Gung Wu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : human somatosensory system; nerve organisation; peripheral nerve; cutaneous mechanoreceptors; skin innervation; microneurography; microelectrode;

    Abstract : With regard to the intraneural organisation of peripheral nerves findings obtained from previous anatomical and physiological studies appear to be controversial. The conventional concept seems to be that peripheral nerves lack a detailed topographical organisation. READ MORE

  5. 13. A pathway for pleasant touch: linking peripheral receptors to central processing and hedonic experience

    Author : Line Sofie Löken; Göteborgs universitet; []
    Keywords : pleasant; touch; microneurography; human; CT afferent; unmyelinated;

    Abstract : This thesis investigates the mechanisms underpinning pleasant touch, describes a pathway from peripheral nerve endings in the skin to the insular cortex, and relates these findings to the subjective hedonic experience of touch. In Paper I, the relationship between primary afferent encoding and perception of pleasantness was investigated by combining microneurography recordings from human mechanoreceptors with psychophysical measurements during soft brush stroking at 6 different velocities between 0.

  6. 14. Intrathecal adenosine for treatment of acute pain : safety assessments and evaluation in experimental, surgical and labour pain

    Author : Kerstin Rane Lindgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adenosine; intrathecal; central sensitisation; neurotoxicity; spinal cord blood flow; analgesia; anaesthetic requirement; postoperative pain; labour pain.;

    Abstract : Adenosine is an endogenous compound present in all cells in the body with a wide range of physiological effects. Exogenous administration of adenosine is used clinically as an antiarrytmic agent and as a vasodilator. READ MORE
