  1. 6. Spotting pain in the brain. Towards a useful animal model of pain

    Författare :Tanja Jensen; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; analgesics; freely moving rat; microelectrode; Nociception; Primary somatosensory cortex; Sedatives;

    Sammanfattning : Current models of pain in conscious animals usually scores nocifensive responses. However, it is still unclear to what extent these responses are related to, for instance, the sensory discriminative or affective aspects of pain. LÄS MER

  3. 7. Management of thoracoabdominal aortic aneurysms and dissections : with emphasis on spinal cord protection in aneurysm repair and non-surgical treatment of type-B dissection

    Författare :Anders Winnerkvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Aortic cross-clamping; cerebrospinal fluid drainage; GFAp; NFL; retrograde venous spinal cord perfusion; somatosensory evoked potentials; S100B; thoracoabdominal aortic aneurysm; type B aortic dissection.;

    Sammanfattning : Thoraco-abdominal aortic aneurysms and dissections are two very serious disease processes which entail a high risk of vessel rupture and death. Their specific treatment strategies have several similarities which have formed a base for this thesis. LÄS MER

  4. 8. Idiopathic scoliosis : radiographic, neurophysiologic and psychologic aspects

    Författare :Yngvi Ólafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :idiopathic scoliosis; brace treatment; back surface analysis; self-image; somatosensory testing;

    Sammanfattning : The aim of this thesis was to study brace treatment outcome, the brace effect on electromyographic muscle responses and self image, possible occurrence of somatosensory dysfunction and the descriptive power of surface topography contra radiography, in idiopathic scoliosis. There were 64 patients in a retrospective 4. LÄS MER

  5. 9. New functional and anatomical aspects of the organisation of human peripheral nerve

    Författare :Rolf Ekedahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Somatosensory system; Peripheral nerve organisation; somatotopy; modalitysegregation; cutaneous mechanoreceptors; Human.Huddinge 1996;

    Sammanfattning : The functional topography of peripheral nerves has been studied by various indirect electrophysiological and histological methods. Even though some studies have suggested the presence of a somatotopical arrangement of nerve fibres, the prevailing view is that a random distribution of nerve fibres develops in the nerve due to the repeated rearrangement of nerve fascicles along their centripetal course.

  7. 10. Different neurophysiological methods for studying the vestibular system : evaluation of old methods and development of a new test procedure

    Författare :Birgitta Larsby; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Different methods were used to study the physiology and anatomy of the vestibular system. 1) A primary vestibular cortical area in the cat was located and tested for somatosensory inflow by recordings of vestibular evoked potentials and extracellular single unit activity.
