  1. 1. Imaging imagining actions

    Författare :CJ Olsson; Lars Nyberg; A.Mark Williams; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mental training; motor training; novices; imaging; athletes; fMRI; internal imagery; motor representation; brain systems; practice; learning; transfer; active; Physiology; Fysiologi;

    Sammanfattning : Mental training has been studied extensively for the past century but we are still not completely sure how it affects brain and behavior. The aim of this doctoral thesis was to examine one aspect of mental training i.e. motor imagery. LÄS MER

  2. 2. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Författare :Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER

  3. 3. Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response

    Författare :Stina Lindqvist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Marine sediments; Early diagenesis; Bioturbation; Functional groups; Benthic fluxes; Imaging; Ecosystem function; Sediment reworking; Transport proxies; Fluorescent particles;

    Sammanfattning : Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in the biosphere (e.g. C, N, P, Fe, Mn and S). LÄS MER

  4. 4. Shared component processes in working memory and long-term memory : Insights from functional brain imaging

    Författare :Petter Marklund; Lars Nyberg; Håkan Fisher; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psychology; Psykologi; Psychology; psykologi;

  5. 5. Stereotactic imaging in functional neurosurgery

    Författare :Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; pallidotomy; thalamotomy; Parkinson s disease; essential tremor; CT; MRI; neurokirurgi; Neurosurgery;

    Sammanfattning : Background: The birth of stereotactic functional neurosurgery in 1947 was to a great extent dependent on the development of ventriculography. The last decades have witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders. LÄS MER
