  2. 1. Quantitative Magnetic Resonance Imaging of the Brain : Applications for Tissue Segmentation and Multiple Sclerosis

    Author : Janne West; Peter Lundberg; Anne-Marie Landtblom; Marcel Jan Bertus Warntjes; Örjan Smedby; Olof Dahlqvist Leinhard; Per Thunberg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Magnetic resonance imaging (MRI) is a sensitive technique for assessing white matter (WM) lesions in multiple sclerosis (MS), but there is a low correlation between MRI findings and clinical disability. Because of this, other pathological changes are of interest, including changes in normal appearing white matter (NAWM) and diffusely abnormal white matter (DAWM). READ MORE

  4. 2. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

    Author : Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; brain plasticity; structural plasticity; magnetic resonance imaging; voxel-based morphometry; tractography; connectivity; motor cortex; posterior parietal cortex; cerebellum; vesicular glutamate transporter;

    Abstract : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. READ MORE

  5. 3. Radiological studies of LMNB1-related autosomal dominant leukodystrophy and Marinesco-Sjögren syndrome

    Author : Johannes Finnsson; Raili Raininko; Eva Kumlien; Isabella Björkman-Burtscher; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Leukoencephalopathies; hereditary central nervous system demyelinating diseases; autonomic dysfunction; adult-onset; neuromuscular disease; pediatric; neuro-ophtalmology; ataxia;

    Abstract : There are approximately 6000 to 8000 rare diseases, each with a prevalence of less than 1 / 10 000, but in aggregate affecting 6 to 8% of the population. It is important to evaluate disease development and progression to know the natural course of any disease. READ MORE

  6. 4. Brain Plasticity and Upper Limb Function After Stroke: Some Implications for Rehabilitation

    Author : Påvel Lindberg; Jörgen Borg; Hans Forssberg; Margareta Engardt; Cornelius Weiller; Uppsala universitet; []
    Keywords : Neurosciences; Stroke; Upper Limb; Brain Plasticity; Functional MRI; Diffusion Tensor Imaging; Transcranial Magnetic Stimulation; Neurovetenskap;

    Abstract : Neuroimaging and neurophysiology techniques were used to study some aspects of cortical sensory and motor system reorganisation in patients in the chronic phase after stroke. Using Diffusion Tensor Imaging, we found that the degree of white matter integrity of the corticofugal tracts (CFT) was positively related to grip strength. READ MORE

  7. 5. Amyloid precursor protein : cellular studies and animal models

    Author : Tatjana Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterised by a number of neuropathological features, including extracellular deposits composed primarily of amyloid-β (Aβ) peptides. Aβ is derived from proteolysis of the amyloid precursor protein (APP) by consecutive action of β and γ-secretases. READ MORE
