  1. 21. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

    Författare :Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

    Sammanfattning : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

  4. 23. Methodological developments in small animal PET neuroimaging

    Författare :Miklós Tóth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Positron emission tomography (PET) is a nuclear imaging technique using a multidisciplinary approach to functionally visualize processes in the brain or other living tissue. It is capable to determine the pharmacokinetic and pharmacodynamic properties of a molecule in the CNS, with a low risk of side effects on the subject. LÄS MER

  5. 24. Measuring brain functions : statistical tests for neuroimaging data

    Författare :Anders Ledberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis is about statistical methods for functional neuroimaging data. With functional neuroimaging, here understood as PET and fMRI, the activity of the human brain can be studied in vivo. LÄS MER

  7. 25. Depression and cognition in the elderly : neuroimaging perspective

    Författare :Aleksandra Lebedeva; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis examines the relationship between depression and brain structure in the elderly with (Study I, III) and without (Study II, IV) cognitive impairment (Alzheimer’s disease and mild cognitive impairment). Individuals from four independent cohorts were included. LÄS MER
