  2. 1. fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications

    Author : Andreas Weibull; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smoothing; physiological noise; spatial resolution; primary somatosensory cortex; cortical reorganisation; brain plasticity; fMRI; partial volume effects;

    Abstract : Functional magnetic resonance imaging (fMRI) is a widely used tool for studying brain function in vivo. The technique is based on acquiring brain images sensitive to the physiological response following neural activation, and hence, allows brain activity to be examined and documented. READ MORE

  4. 2. On mapping the human somatosensory cortex : fMRI and PET imaging

    Author : Jeremy Young; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Mapping; anatomy; connectivity; somatosensory; attention; organisation; somatotopy; fMRI; PET; rCBF; cytoarchitecture.;

    Abstract : This work is based on experiments and simulations for the purpose of mapping the human somatosensory cortex. By using a combination of structural mapping (cytoarchitecture), connectivity mapping, functional mapping, and somatotopical mapping an overview of the organisation of the human somatosensory cortex at different levels is possible.

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

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

    Abstract : 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.

  6. 4. Spinal Cord Processing of Sensory Information: Spatial Organization and Adaptive Mechanisms

    Author : Anders Levinsson; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; transplantatioin; pain; sensorimotor; plasticity; reflex; neuropsykologi; neurofysiologi;

    Abstract : Principles for sensorimotor transformation and plasticity in the spinal cord and functional repair in the root-avulsed spinal cord were studied. A comparative study confirmed that the nociceptive withdrawal reflex (NWR) system is composed of reflex modules, with each performing a finely tuned transformation of skin sensory input to activity in one muscle.
