  1. 1. Diffusion tensor magnetic resonance imaging of the brain : Tractography analysis with application in healthy individuals and patients

    Författare :Johanna Mårtensson; Elna-Marie Larsson; Jimmy Lätt; Danielle van Westen; Tim Dyrby; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Diffusion Tensor Imaging; Tractography; white matter tracts; Radiology; Radiologi;

    Sammanfattning : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. LÄS MER

  3. 2. White matter connections : developmental neuroimaging studies of the associations between genes, brain and behavior

    Författare :Fahimeh Darki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Development of cognitive abilities across childhood and adulthood parallels brain maturation in typically developing samples. Cognitive abilities such as reading and working memory have been linked to neuroimaging measures in relevant brain regions. LÄS MER

  4. 3. Brain imaging in extremely preterm infants : relations to perinatal factors and outcome

    Författare :Georgios Alexandrou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The survival of extremely preterm infants has improved over the last decades along with the advances in perinatal care. These immature children are born at a vulnerable stage of brain development, before entering the third trimester of gestation, and are at an increased risk for brain injuries, atypical brain development and subsequent adverse neurodevelopment.

  5. 4. The relation among aging, dopamine-regulating genes, and neurocognition

    Författare :Xin Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : When people are getting old, they often feel increasingly harder to concentrate, and become slower and more inflexible during tasks that involve focused attention, information maintenance in the face of distractions, and when fast switching according to changing goals is required. These cognitive functions are collectively referred to as working memory (WM). LÄS MER

  7. 5. Diffusion Tensor Imaging and Tractography in Epilepsy Surgery Candidates

    Författare :Daniel Nilsson; Göteborgs universitet; []
    Nyckelord :epilepsy; epilepsy surgery; temporal lobe resection; optic radiation; diffusion tensor imaging; tractography;

    Sammanfattning : In selected patients with medically refractory epilepsy, surgical treatment can render the patients seizure free or significantly reduce seizure frequency. Temporal lobe resection (TLR) for temporal lobe epilepsy (TLE) is the most commonly performed epilepsy surgery procedure. LÄS MER
