  1. 11. Age differences in arousal, perception of affective pictures, and emotional memory enhancement : Appraisal, Electrodermal activity, and Imaging data

    Författare :Joachim Gavazzeni; Håkan Fischer; Richard J. Davidson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aging; Affective function; subjective ratings; SCRs; FMRI; Pictures; Emotional memory enhancement; Bottom-up and Top-down processing; Psychology; Psykologi; psykologi; Psychology;

    Sammanfattning : In contrast to effortful cognitive functions, emotional functioning may remain stable or even be enhanced in older adults. It is unclear how affective functions in aging correspond to subjective experiences and physiological changes. LÄS MER

  3. 12. Functional aspects of tactile directional sensibility

    Författare :Helena Backlund; Göteborgs universitet; []
    Nyckelord :Human; directional sensibility; hairy skin; hemispherectomy; postural control; glabrous skin; fMRI; psychophysics;

    Sammanfattning : Tactile directional sensibility, i.e. the ability to tell the movement direction of a moving tactile stimulus, depends on the parallel processing of spatiotemporal information and information about changes in the pattern of skin tension. LÄS MER

  4. 13. 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.

  5. 14. Advanced MRI Data Processing

    Författare :Joakim Rydell; Magnus Borga; Hans Knutsson; Göran Starck; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging MRI ; functional Magnetic Resonance Imaging fMRI ; spatial filtering; robust correlation estimation; correcting artifacts; Medical informatics; Medicinsk informatik;

    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

  7. 15. Fatigue after traumatic brain injury : exploring novel methods for diagnosis and treatment

    Författare :Nils Berginström; Anna Nordström; Peter Nordström; Lars Nyberg; Jan Lexell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; fatigue; OSU6162; randomized clinical trials; functional magnetic resonance imaging; neuropsychology; structural magnetic resonance imaging; white matter hyperintensities; rehabiliteringsmedicin; Rehabilitation Medicine;

    Sammanfattning : Background: Traumatic brain injury (TBI) is one of the most common causes of disability and mortality. While some patients recover quickly, especially at the mild side of the injury severity continuum, many will experience symptoms for years to come. LÄS MER
