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

    Författare :Erika Dahlin; Lars Nyberg; Anna Stigsdotter Neely; Torkel Klingberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; 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;

    Sammanfattning : 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.

  3. 2. Diving and the brain

    Författare :Anders Rosén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomarkers; brain; central nervous system; decompression sickness; dive research; diving; neuronal damage; saturation diving; tau protein; venous gas embolism; neurofilament light; glial fibrillary acid protein; tau; VGE;

    Sammanfattning : Abstract Introduction There are reports that long-term diving is associated with cognitive impairments. This raises the question if diving itself is harmful to the brain in the absence of decompression sickness or hypoxia. LÄS MER

  4. 3. Cognition, Adherence and Stigma in Schizophrenia. The COAST study

    Författare :Cecilia Brain; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; schizophrenia; adherence; Medication Event Monitoring System; antipsychotics; pill count; drug attitude; stigma; discrimination; relatives´burden;

    Sammanfattning : Schizophrenia is a serious stigmatizing illness. Antipsychotic medication is a cornerstone in treatment. Non-adherence is a predictor of poor outcome leading to relapse, poor functioning, high mortality and costs. Reported adherence rates vary (8-86%). LÄS MER

  5. 4. Cyanide and central nervous system : a study with focus on brain dopamine

    Författare :Gudrun Cassel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CNS; cyanide; dopaminergic system; convulsions; receptor binding; tyrosine hydroxylase; monoamine oxidase; extracellular release; inositol phosphate; GABA; GAD;

    Sammanfattning : The brain is a major target site in acute cyanide intoxication, as indicated by several symptoms and signs. Cyanide inhibits the enzyme cytochrome oxidase. This inhibition causes impaired oxygen utilization in all cells affected, severe metabolic acidosis and inhibited production of energy. LÄS MER

  7. 5. Intracranial Pressure in Traumatic Brain Injury

    Författare :Sima Shahsavari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain Swelling; Cerebral Autoregulation; Secondary Brain Injury; Traumatic Brain Injury; Cerebral Compliance; Intracranial Dynamics; Intracranial Pressure;

    Sammanfattning : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainely focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity (ICP) has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. LÄS MER
