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

    Författare :Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Stroke and Functional Recovery - An experimental study on environmental influence and gene expression after cortical infarcts in the rat

    Författare :Anette Risedal; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; cortical infarct; rat; enriched environment; functional recovery; brain-derived neurotrophic factor; inducible transcription factors; neuropsykologi; neurofysiologi; Neurologi; glucocorticoids; neurophysiology;

    Sammanfattning : Abstract Stroke is the third leading cause of death in the western world, and the number one cause of disability. 85% of all strokes are ischemic. Most stroke survivors will experience recovery of function. The mechanisms behind this improvement are partly unknown, but may involve elements of both compensation and restoration. LÄS MER

  4. 3. Gene Expression Changes and Brain Plasticity after Experimental Stroke

    Författare :Mattias Rickhag; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; apolipoprotein D; regeneration; brain ischemia; functional recovery;

    Sammanfattning : Stroke is the most common life-threatening neurological disease and ranks as the third leading cause of death in major industrialized countries. It is also the leading cause of serious long-term disability and about sixty percent of survivors have disabilities in their extremities. LÄS MER

  5. 4. Children with Cochlear Implants : Cognition and Reading Ability

    Författare :Malin Wass; Björn Lyxell; Birgitta Sahlén; Birgitta Larsby; Anita McAllister; Linköpings universitet; []
    Nyckelord :Cochlear implants; children; working memory; phonological skills; lexical access; reading ability; Cochleaimplantat; barn; arbetsminne; fonologiska färdigheter; lexikal aktivering; läsförmåga.; MEDICINE; MEDICIN;

    Sammanfattning : The present thesis investigated cognitive ability in children with severe to profound hearing impairment who have received cochlear implants (CIs). The auditory stimulation from a cochlear implant early in life influences most cognitive functions as a consequence of the plasticity of the brain in the young child. LÄS MER

  7. 5. Endogenous and treatment-induced neuroplasticity in mouse models of Parkinson's disease

    Författare :Francesco Bez; Basala gangliernas patofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Parkinson´s disease (PD) is an age-related neurodegenerative disorder characterized by a loss of nigral dopamine (DA) neurons that project their axons to the striatum. Striatal DA depletion causes the typical motor symptoms of PD. LÄS MER
