  1. 1. 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

  3. 2. Somatosensory dysfunctin in fibromyaligia : implications for pathophysiological mechanisms

    Författare :Eva Kosek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :allodynia; diffuse noxious inhibitory controls DNIC ; fibromyalgia; hyperesthesia; isometric contraction; pain modulation; pain inhibition; pressure algometry; quantitative sensory testing; sensitivity; sensitization; tourniquet test; v;

    Sammanfattning : Fibromyalgia is a chronic pain syndrome characterized by generalized pain, tenderness, disturbed sleep and pronounced fatigue. The pathophysiology is unknown but peripheral mechanisms (i.e., muscle ischemia) as well as central mechanisms (dysfunction in endogenous pain modulation) have been implicated. LÄS MER

  4. 3. 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

  5. 4. A tailored biocompatible neural interface for long term monitoring in neural networks

    Författare :Per Köhler; Neuronano Research Center (NRC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-machine interfaces; neuroinflammation; somatosensory cortex; hyperalgesia; allodynia;

    Sammanfattning : Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. LÄS MER

  7. 5. Neuropathic pain : somatosensory functions related to spontaneous ongoing pain, mechanical allodynia and pain relief

    Författare :Åsa Landerholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Peripheral neuropathic pain; Central post stroke pain; Dynamic mechanical allodynia; Static mechanical allodynia; Dysesthesia; Quantitative sensory testing; Spinal cord stimulation.;

    Sammanfattning : Introduction and aim: Patients with neuropathic pain suffer from spontaneous ongoing pain and from abnormal stimulus-evoked pain, e.g., allodynia. LÄS MER
