1. 1. Mind your Language, All Right? Performance-dependent neural patterns of language

   Författare :Helene van Ettinger-Veenstra; Maria Engström; Peter Lundberg; Thomas Karlsson; Anita McAllister; Karsten Specht; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Language ability; performance; fMRI; functional magnetic resonance imaging; Broca; Wernicke; temporal lobe; inferior frontal gyrus; reading; fluency; lateralization; lateralisation; right hemisphere; performance-dependent; neural activation;

   Sammanfattning : The main aim of this dissertation was to investigate the difference in neural language patternsrelated to language ability in healthy adults. The focus lies on unraveling the contributions of theright‐hemispheric homologues to Broca’s area in the inferior frontal gyrus (IFG) and Wernicke’s areain the posterior temporal and inferior parietal lobes.

3. 2. Visual and tactile neglect

   Författare :Haukur Hjaltason; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Visual neglect; tactile neglect; premotor neglect; perceptual neglect; bisection tasks; darkness; tactile exploration; right hand use; right hemisphere activation; three-dimensionality; figure-ground contrast; chronic;

   Sammanfattning : Neglect patients typically fail to report, respond, or orient to information presented in locations further away from the side of the brain lesion. Neglect is most often reported after acute stroke, and is more severe and more frequent after right hemisphere damage. LÄS MER

4. 3. Focal spasticity therapy : effects on motor function, health related quality of life, and central nervous system plasticity

   Författare :Ulla Bergfeldt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Adults; cerebral palsy; stroke; traumatic injury; spasticity; botulinum toxin -type A ; physical therapy; health-related quality of life; functional MRI; reproducibility; healthy subjects; motor task; data-glove;

   Sammanfattning : The overall aim of the thesis was to obtain knowledge about the effects of a comprehensive spasticity management from several perspectives. To achieve this goal, we investigated the effects on motor functions, health-related quality of life, and the central nervous system correlates to a motor task. LÄS MER

5. 4. Molecular Adaptations in the Endogenous Opioid System in Human and Rodent Brain

   Författare :Muhammad Zubair Hussain; Georgy Bakalkin; Anita Hansson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endogenous Opioid System; Dynorphins; Lateralization; Alcohol Dependence; Emotions; Traumatic Brain Injury; Anterior Cingulate Cortex; Dorsal Striatum; Neuroscience; Neurovetenskap;

   Sammanfattning : The aims of the thesis were to examine i) whether the endogenous opioid system (EOS) is lateralized in human brain areas involved in processing of emotions and pain; ii) whether EOS responses to unilateral brain injury depend on side of lesion, and iii) whether in human alcoholics, this system is involved in molecular adaptations in brain areas relevant for cognitive control of addictive behavior and habit formation.The main findings were that (1) opioid peptides but not opioid receptors and classic neurotransmitters are markedly lateralized in the anterior cingulate cortex involved in processing of  positive and negative emotions and affective component of pain.

7. 5. 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
