  1. 1. Fear, Startle, and Fear-Potentiated Startle : Probing Emotion in the Human Brain

    Författare :Anna Pissiota; Mats Fredrikson; Scott Rauch; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psychology; anxiety; attention; brain; fear; fear-potentiated startle; human; neuroimaging; positron emission tomography; posttraumatic stress disorder; regional cerebral blood flow; startle; startle habituation; symptom provocation; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : The present thesis explored the neurobiological basis of three aspects of defense behaviors in humans. Positron emission tomography methodology was used, and changes in regional cerebral blood flow (rCBF) were measured as an index of neural activity. LÄS MER

  3. 3. Non-invasive Functional Neuroimaging for Localizing Epileptic Brain Activity

    Författare :Yazdan Shirvany; Chalmers University of Technology; []
    Nyckelord :Mathematical Dipole; Finite Element Method; Source localization; Structural Magnetic Resonance Imaging; Forward Problem; Inverse Problem; Particle Swarm Optimization; Non-invasive EEG; Somatosensory Evoked Potentials; Epileptic Spike; Functional Neuroimaging;

    Sammanfattning : Surgical therapy has become an important therapeutic alternative for patients with medically intractable epilepsy. Correct and anatomically precise localization of the epileptic focus, preferably with non-invasive methods, is the main goal of the pre-surgical epilepsy diagnosis to decide if resection of brain tissue is possible.

  4. 4. Genotypic and phenotypic spectrum of mitochondrial diseases with focus on early onset mitochondrial encephalopathies

    Författare :Kalliopi Sofou; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondrial diseases; mitochondrial encephalopathy; Alpers syndrome; Leigh syndrome; neuroimaging; whole exome sequencing;

    Sammanfattning : Early-onset mitochondrial encephalopathies comprise a challenging group of neurodegenerative disorders. This is due to their progressive nature, often leading to major disability and premature death, as well as their diagnostic complexity and lack of customized treatments. LÄS MER

  5. 5. Brain Structure and Function in Adolescents with Atypical Anorexia Nervosa

    Författare :Gaia Olivo; Helgi B. Schiöth; Christian Benedict; Jessica Mwinyi; Andreas Jansen; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; MRI; functional MRI; fMRI; magnetic resonance imaging; neuroimaging; brain imaging; anorexia nervosa; eating disorders; neuroscience; adolescents; Medicinsk vetenskap; Medical Science; Neuroscience; Neurovetenskap;

    Sammanfattning : Atypical anorexia nervosa (AAN) has a high incidence in adolescents, resulting in significant morbidity and mortality. The weight loss is generally less pronounced than that experienced in full-syndrome anorexia nervosa (AN), but the medical consequences can be as severe. LÄS MER
