• Evoked potentials in the Atlantic cod following putatively innocuous and putatively noxious electrical stimulation: a minimally invasive approach 

      Ludvigsen, Stian; Stenklev, Niels Chr.; Johnsen, Helge K.; Laukli, Einar; Matre, Dagfinn; Aas-Hansen, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Aspects of peripheral and central nociception have previously been studied through recording of somatosensory evoked potentials (SEPs) to putative noxious stimuli in specific brain regions in a few freshwater fish species. In the present study, we describe a novel, minimally invasive method for recording SEPs from the central nervous system of the Atlantic cod (Gadus morhua). Cutaneous ...
    • Shift work, low-grade inflammation, and chronic pain: a 7-year prospective study

      <i>Objectives</i> - We investigated prospective associations of shift work with chronic pain and C‐reactive protein (CRP), an indicator of inflammation. Furthermore, we elucidated CRP as a possible mediator and/or moderator of effects of shift work on pain.<br><br> <i>Methods</i> - Data from a 7 years follow‐up study were analyzed (<i>N</i> = 2323). Shift work and chronic pain of “neck/shoulder”, ...
