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

    Author : Anna Pissiota; Mats Fredrikson; Scott Rauch; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Yazdan Shirvany; Chalmers University of Technology; []
    Keywords : 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;

    Abstract : 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. Autism and ADHD in children with cerebral palsy

    Author : Magnus Påhlman; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; cerebral palsy; autism spectrum disorder; attention-deficit hyperactivity disorder; children; impairments; screening; prevalence; neuroimaging;

    Abstract : BACKGROUND: Autism spectrum disorder (autism) and attention-deficit/hyperactivity disorder (ADHD) are likely underdiagnosed in children with cerebral palsy (CP). Early identification of impairments is important for adequate understanding and support. READ MORE

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

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

    Abstract : 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. READ MORE
