1. 1. fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications

   Författare :Andreas Weibull; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smoothing; physiological noise; spatial resolution; primary somatosensory cortex; cortical reorganisation; brain plasticity; fMRI; partial volume effects;

   Sammanfattning : Functional magnetic resonance imaging (fMRI) is a widely used tool for studying brain function in vivo. The technique is based on acquiring brain images sensitive to the physiological response following neural activation, and hence, allows brain activity to be examined and documented. LÄS MER

3. 2. Advanced clinical MRI for better outcome in epilepsy surgery. Focusing on fMRI and prediction of verbal memory decline

   Författare :Maria Strandberg; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3T MRI; surface coils; epilepsy surgery; fMRI; TLE; lateralization index; MTL; verbal encoding;

   Sammanfattning : Abstract Aim: The aim of the thesis was to evaluate the use of advanced MRI technology to improve results of epilepsy surgery, with focus on language and memory functions. Methods: In paper I, 25 patients with drug-resistant epilepsy were retrospectively included in the study for having been referred to high resolution 3T MRI with and without surface coils. LÄS MER

4. 3. Functional brain imaging of sensorimotor dysfunction and restoration : investigations of discomplete spinal cord injury and deep brain stimulation for essential tremor

   Författare :Amar Awad; Johan Eriksson; Patric Blomstedt; Richard Levi; Lars Nyberg; Rick Helmich; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sensorimotor control; fMRI; discomplete spinal cord injury; essential tremor; deep brain stimulation; cerebello-thalamo-cerebral circuit; Physiology; fysiologi; neurokirurgi; Neurosurgery; Neurology; neurologi; rehabiliteringsmedicin; Rehabilitation Medicine;

   Sammanfattning : The nervous system exists to generate adaptive behaviour by processing sensory input from the body and the environment in order to produce appropriate motor output, and vice versa. Consequently, sensorimotor dysfunction is the basis of disability in most neurological pathologies. LÄS MER

5. 4. Scalable Bayesian spatial analysis with Gaussian Markov random fields

   Författare :Per Sidén; Mattias Villani; Anders Eklund; Håvard Rue; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial statistics; Bayesian statistics; Gaussian Markov random fields; fMRI; Machine learning; Spatial statistik; Bayesiansk statistik; Gaussiska Markov-fält; fMRI; Maskininlärning;

   Sammanfattning : Accurate statistical analysis of spatial data is important in many applications. Failing to properly account for spatial autocorrelation may often lead to false conclusions. LÄS MER

7. 5. Brain reactivity in leading and following, and the SSP in Japanese : A minimal model of rhythm tapping for leading and following showing temporal and insular reactivity, and a Swedish to Japanese translation of an inventory to assess personality factors for leaders and followers

   Författare :Lykke Silfwerbrand; Malin Gingnell; Lisa Ekselius; Yasuharu Koike; Pär Nyström; Stina Bergman Blix; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Leading; Following; fMRI; finger tapping; Swedish Universities Scales of Personality; SSP; SSPJ-11; reliability; cross-cultural translation;

   Sammanfattning : To understand more about the neural underpinnings for leading and following is the driving force behind this thesis. To do so, there is a need to study leading and following on a basic level. LÄS MER
