  3. 2. Imaging imagining actions

    Författare :CJ Olsson; Lars Nyberg; A.Mark Williams; Umeå universitet; []
    Nyckelord :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

  4. 3. Imaging Anxiety : Neurochemistry in Anxiety Disorders Assessed by Positron Emission Tomography

    Författare :Andreas Frick; Mats Fredrikson; Tomas Furmark; David J Nutt; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fear; Brain; Serotonin; Neurokinin; Substance P; Psychology; Psykologi;

    Sammanfattning : Anxiety disorders, including social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD) are common and disabling conditions. Largely based on animal and pharmacological studies, both the serotonergic and substance P/neurokinin-1 (SP/NK1) systems have been implicated in their underlying pathology. LÄS MER

  5. 4. Coherent Diffractive Imaging with X-ray Lasers

    Författare :Max Felix Hantke; Filipe R. N. C. Maia; Janos Hajdu; Martin Svenda; Edgar Weckert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

    Sammanfattning : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. LÄS MER

  7. 5. PET and MR imaging in prostate cancer

    Författare :Kristina Sandgren; Tufve Nyholm; Joakim Jonsson; Camilla Thellenberg-Karlsson; Lennart Blomqvist; Heidi Lyng; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; PSMA; MRI; PET MRI; imaging; prostate cancer; intraprostatic tumour detection; radiofysik; radiation physics;

    Sammanfattning : The current risk assessment of prostate cancer (PC) relies on histopathological samples from biopsies and clinical variables such as prostate-specific antigen (PSA). However, this comes with uncertainties and in some cases it can be challenging to separate patients who would benefit from radical treatment and those who would not. LÄS MER
