  1. 21. Neural correlates of skilled movement : functional mapping of the human brain with fMRI and PET

    Författare :H Henrik Ehrsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Brain; manual dexterity inter-limb coordination; kinesthesia; motor imagery;

    Sammanfattning : Humans have unique abilities to perform certain types of skilled voluntary movements. In this thesis we examine the neural substrates of. (i) fine digit actions, in particular the control of fingertip forces during manipulation, and (ii) the coordination of voluntary movements of different limbs. LÄS MER

  3. 22. Atlas-Based Fusion of Medical Brain Images : Methods and Applications

    Författare :Roger Lundqvist; Hans Knutsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Bildanalys; Image analysis; Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Sammanfattning : This thesis focuses on the development of methods for fusion of information from medical brain scans. The concept of medical image fusion refers to the process of extracting and utilising information from several scans simultaneously in the analysis and diagnosis of patients. LÄS MER

  4. 23. The neurophysiology of working memory : functional mapping of the human brain with positron emission tomography

    Författare :Torkel Klingberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Working memory (WM) refers to the retention, or keeping on-line, of information over short periods of time. WM is thought to be important for a variety of cognitive functions, including problem solving, learning and reading. LÄS MER

  5. 24. Estrogen receptor gene activity within the brain and the relation to psychiatric disorders : mapping and function

    Författare :Marie Österlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :steroid hormone; ER system; in situ hybridization; rnRNA; ER serotonin; depression; affective disorders;

    Sammanfattning : Estrogens have for a long time been known to regulate neuroendocrine functions in the central nervous system (CNS), primarily related to reproduction. In recent years estrogens have been found to also modulate many other brain functions, for example mood and cognition. LÄS MER

  7. 25. On mapping the human somatosensory cortex : fMRI and PET imaging

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

    Sammanfattning : 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.
