6. Neuropsychological Function in Relation to Structural and Functional Brain Changes in Alzheimer’s Disease
Abstract : The aim of this doctoral thesis was to study neuropsychological function in relation to structural and functional brain changes in Alzheimer´s disease (AD). In the first study relations between hippocampal volume, neuropsychological function and limbic-hypothalamic-pituitary-adrenal (LHPA) axis disturbances in AD were investigated with magnetic resonance imaging (MRI).

7. Cross-functional brain imaging of attention, memory, and executive functions : Unity and diversity of neurocognitive component processes
Abstract : The central theme of the present thesis revolves around the exploration of similarities and differences in brain activity patterns invoked by the component processes underlying mnemonic, executive and attentional functions. The primary aim was to identify and functionally characterize commonly recruited brain regions in terms of shared component processes, which has been a largely neglected area of research in cognitive neuroscience.

8. Neurocognitive and endocrine dysfunction in women with exhaustion syndrome
Abstract : Stress has emerged as one of the most important factors to consider in psychiatric diagnoses and has become a common reason for long-term sick leave (LTSL). Roughly 50% of LTSL due to psychiatric diseases are thought to be associated with work-related stress. READ MORE

9. The conscious brain : Empirical investigations of the neural correlates of perceptual awareness
Abstract : Although consciousness has been studied since ancient time, how the brain implements consciousness is still considered a great mystery by most. This thesis investigates the neural correlates of consciousness by measuring brain activity with functional magnetic resonance imaging (fMRI) while specific contents of consciousness are defined and maintained in various experimental settings.

10. The effect of intermittent theta-burst stimulation over the dorsomedial prefrontal cortext on brain activity in depression
Abstract : Repetitive transcranial magnetic stimulation is an emerging alternative for treatment-resistant depression, with ongoing developments in stimulation protocols and treatment targets. As such, intermittent theta-burst stimulation (iTBS) delivered over the dorsomedial prefrontal cortex (dmPFC) has shown promise, however establishing a need for neuroimaging studies to further understand the treatment mechanisms.
