    Sammanfattning : Magnetic resonance imaging (MRI) is a very versatile imaging modality which can be used to acquire several different types of images. Some examples include anatomical images, images showing local brain activation and images depicting different types of pathologies. LÄS MER

  4. 8. Adaptive analysis of functional MRI data

    Författare :Ola Friman; William M. Wells III; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Functional Magnetic Resonance Imaging (fMRI) is a recently developed neuroimaging technique with capacity to map neural activity with high spatial precision. To locate active brain areas, the method utilizes local blood oxygenation changes which are reflected as small intensity changes in a special type of MR images. LÄS MER

  5. 9. Neural Mechanisms Determining Visuospatial Working Memory Tasks : Biophysical Modeling, Functional MRI and EEG

    Författare :Fredrik Edin; Jesper Tegnér; Klaas Stephan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

    Sammanfattning : Visuospatial working memory (vsWM) is the ability to temporarily retain goal-relevant visuospatial information in memory. It is a key cognitive function related to general intelligence, and it improves throughout childhood and through WM training. LÄS MER

  7. 10. Design of Functional Polymeric Nanoparticles for Biomedical Applications

    Författare :Heba Asem; Eva Malmström; Tim Bowden; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biodegradable polymers; SPION; PISA; RAFT; nanoparticles; drug delivery; cytotoxicity; MRI; in vivo fluorescence imaging; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Most of the devastating diseases such as cancer are relatively incurable and have high risks of relapse. Therefore, persistent endeavors have been devoted to improve patient survival rate and quality of life. LÄS MER
