1. Imaging imagining actions
Sammanfattning : Mental training has been studied extensively for the past century but we are still not completely sure how it affects brain and behavior. The aim of this doctoral thesis was to examine one aspect of mental training i.e. motor imagery. LÄS MER
2. Brain Structure and Function in Adolescents with Atypical Anorexia Nervosa
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
3. Functional Magnetic Resonance Imaging for Clinical Diagnosis : Exploring and Improving the Examination Chain
Sammanfattning : Functional Magnetic Resonance Imaging (fMRI) is a relatively new imaging technique, first reported in 1992, which enables mapping of brain functions with high spatial resolution. Functionally active areas are distinguished by a small signal increase mediated by changes in local blood oxygenation in response to neural activity. LÄS MER
4. Innate and Conditioned Fear : Investigating Responses to Threat using Psychophysiology, Functional Magnetic Resonance Imaging, and Twin Methodology
Sammanfattning : Evolution has shaped systems in the human brain to respond to danger. Some of these systems are innate or hard-wired, while others are learned throughout the entire life span. One commonly studied type of learned threat, conditioned fear, is acquired from experiencing aversive consequences. LÄS MER
5. Mind your Language, All Right? Performance-dependent neural patterns of language
Sammanfattning : The main aim of this dissertation was to investigate the difference in neural language patternsrelated to language ability in healthy adults. The focus lies on unraveling the contributions of theright‐hemispheric homologues to Broca’s area in the inferior frontal gyrus (IFG) and Wernicke’s areain the posterior temporal and inferior parietal lobes.
