  1. 1. Aerobic fitness and healthy brain aging : cognition, brain structure, and dopamine

    Author : Lars Jonasson; Carl-Johan Boraxbekk; Katrine Riklund; Emrah Düzel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerobic exercise; VO2; working memory; executive function; freesurfer; striatum; dopamine; D2-receptors; [11C]raclopride;

    Abstract : Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. READ MORE

  2. 2. Brain function and glucocorticoids in obesity and type 2 diabetes including effects of lifestyle interventions

    Author : Andreas Stomby; Tommy Olsson; Mats Ryberg; Carl-Johan Boraxbekk; Alasdair MacLullich; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; type 2 diabetes; glucocorticoid; cortisol; 11beta hydroxysteroid dehydrogenase type 1; episodic memory; functional magnetic resonance imaging; paleolithic diet; exercise; Internal Medicine; invärtesmedicin; medicin; Medicine;

    Abstract : Background Obesity and associated metabolic dysregulation are linked to impaired cognitive function and alterations in brain structure, which increases the risk of age-related dementia. Increased glucocorticoid (GC) exposure may be a potential mediator of these negative effects on the brain. READ MORE

  3. 3. Effects of PGC1a-induced exercise adaptations in muscle on plasticity and recovery mechanisms in the CNS

    Author : Lars O Karlsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle; brain; exercise; transgenic; PGC-1α; FNDC5; irisin;

    Abstract : In this thesis, we sought to determine if muscle-derived exercise-induced signaling via PGC-1α muscle activation influences neuroplasticity under physiological or pathophysiological conditions. For this purpose, transgenic mice with muscle-specific overexpression of PGC-1α that display an endurance exercise muscle phenotype were evaluated in models of cranial irradiation and photothrombotic stroke, as well as in aging and in a voluntary running paradigm.

  4. 4. Physical exercise as a preventive strategy for disorders affecting the brain. The effect on neuroinflammation

    Author : Martina Svensson; Neuroinflammation; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; Exercise; Neuroinflammation; Microglia; Cytokines; Behavior; Dementia; Depression; Brain ischemia; Alzheimer’s disease; Vascular dementia; Parkinson’s disease;

    Abstract : Physical activity is associated with lower risks of developing dementia, Parkinson’s disease (PD) and depression. Furthermore, being physically active prior to brain ischemia appears to help the recovery process. READ MORE

  5. 5. Brain Regeneration - in vitro and in vivo studies of exercise-related effects on brain plasticity

    Author : Cecilia Bull; Göteborgs universitet; []
    Keywords : brain; neural progenitor cells; stem cells; hippocampus; corpus collosum; rat; mouse; regeneration; neurogenesis; oligodendrogenesis; irradiation; exercise;

    Abstract : Neural stem and progenitor cells in the germinal regions of the adult brain, such as the hippocampus, are of great interest, because they provide the possibility for enhanced brain plasticity or can contribute to endogenous cell replacement after injury or disease. Voluntary exercise was recently shown to robustly induce cellular and structural plasticity, thereby contributing to overall brain health. READ MORE
