  1. 1. On Brain Oedema

    Author : Mårten Jungner; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; brain oedema; fluid therapy; blood-brain barrier;

    Abstract : Traumatic brain injury and bacterial meningitis may at a glance appear as two different disease entities. The host reaction, however, to both trauma and infection involves a strong inflammatory response, with the classical symptomology of rubor, tumor, calor, dolor et functio laesa. READ MORE

  2. 2. Brain morphology and behaviour in the guppy (Poecilia reticulata) : Effects of plasticity and mosaic brain evolution

    Abstract : Understanding how brains have evolved and subsequently culminated in the huge variation in brain morphology among contemporary vertebrate species has fascinated researchers for many decades. It has been recognized that brain morphology is both genetically and environmentally determined. READ MORE

  4. 4. Telomeres and the brain : an investigation into the relationships of leukocyte telomere length with functional and structural attributes of the brain

    Author : Mikael Wikgren; Karl-Fredrik Norrback; Rolf Adolfsson; Göran Roos; Thomas Karlsson; Brenda Penninx; Umeå universitet; []

    Abstract : Telomeres are the outermost parts of linear chromosomes. They consist of tandemly repeated non-coding short nucleotide sequences (TTAGGG in all vertebrates), in humans spanning over the last 2 to 15 kilobase pairs of the chromosome. Due to the end-replication problem, telomeres shorten with each cellular division. READ MORE

  5. 5. Train your brain : updating, transfer, and neural changes

    Author : Erika Dahlin; Lars Nyberg; Anna Stigsdotter Neely; Torkel Klingberg; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; SAMHÄLLSVETENSKAP; MEDICAL AND HEALTH SCIENCES; SOCIAL SCIENCES; cognitive training; executive functioning; transfer; fMRI; brain system; young adults; elderly; practice; neural correlates; individual differences; Experimental brain research; Experimentell hjärnforskning; Cognitive science; Kognitionsforskning; fysiologi; Physiology;

    Abstract : An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks.
