  1. 1. Effects of adult aging on socioemotional perception : Evidence from behavior and brain

    Författare :Diana Persson; Håkan Fischer; Petri Laukka; Louise Phillips; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; age-related differences; social attributes; emotion recognition; oxytocin; fMRI; Psychology; psykologi;

    Sammanfattning : Social perception plays a key role in our everyday interactions. It encompasses the ability to identify, understand, and react to the social cues that others express. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Neurotoxic Effects of Nicotine During Neonatal Brain Development : Critical Period and Adult Susceptibility

    Författare :Emma Ankarberg; Per Eriksson; Richard F. Seegal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; nicotine; neonatal development; behaviour; nicotinic receptors; susceptibility; cholinergic system; paraoxon; PBDE; Biologi; Biology; Biologi;

    Sammanfattning : This thesis examined neurotoxic effects of nicotine exposure during a defined critical period of neonatal brain development in mice.In our environment there are numerous hazardous contaminants that an individual can be exposed to during its entire lifetime. LÄS MER

  5. 4. Adult Neural Stem Cells-Influence of Stroke, Inflammation and Aging

    Författare :Henrik Ahlenius; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammation; Neural stem cells; adult; neurogenesis; stroke; aging; TNF-R1; TNF-α;

    Sammanfattning : Neural stem cells (NSCs) in the embryo generate neurons, astrocytes and oligodendrocytes, the principal cells of the central nervous system (CNS), which contribute to the full diversity of the brain. Some NSCs persist in the adult brain and ensures neurogenesis throughout adult life in the subventricular zone (SVZ) and the subgranular zone (SGZ). LÄS MER

  7. 5. New neurons and astrocytes in the adult brain. Studies on adult rat neural progenitors in vivo and in vitro with special reference to the effects of IGF-I and CNTF regarding proliferation and lineage determination

    Författare :Maria A I Åberg; Göteborgs universitet; []
    Nyckelord :Brain; hippocampus; rat; neurogenesis; progenitor cell; stem cell; ciliary neurotrophic factor; insulin-like growth factor-I; PI3-K; MAPK.;

    Sammanfattning : The hippocampal dentate gyrus in several species, including man, continues to produce new neurons and glial cells in adulthood. The generation of new neurons and glial cells in the adult hippocampus is under strict regulation. Two major events of significance for cell genesis from progenitor cells are proliferation and lineage determination. LÄS MER
