Automated Brain Mapping to Evaluate the Relationship between Neurodegeneration, Cerebral Small Vessel Disease and Structural Covariance Network Disruption in Alzheimer's Disease
… may contribute to AD progression by disrupting structural brain networks that subserve complex cognitive routines. Therefore, the overarching aim of this dissertation is to determine the contribution of cerebral small vessel disease (SVD) versus coexistent neurodegeneration to brain network …

Effects of hormones, genetics, and sex on typical and atypical brain organization
… networks in children with autism or ADHD, using structural covariance magnetic resonance imaging (scMRI). We found overlapping as well as distinct network features across both conditions. Chapter 3 reports an analysis of how gene expression might be associated with the basic building blocs of …

Imaging genetics evidence for the neurodevelopmental model of schizophrenia
… the complex genetic relationship between brain structural phenotypes and schizophrenia. Chapter 1 reviews current imaging and genetic evidence for the neurodevelopmental model of schizophrenia. The neurodevelopmental model of schizophrenia posits that genetic variation and interactions with …

Gray matter covariance networks in the mouse brain
… in several human studies, an approach termed structural covariance MRI (scMRI). Complementary to prevalent brain connectivity modalities like functional and diffusion-weighted imaging, this approach can provide valuable insight into the mutual influence of regional trophic and plastic …

Neurobiological mechanisms of hallucinations in schizophrenia
… of hallucinations, integrating research across structural and functional magnetic resonance imaging (MRI) to elucidate how hallucinations, chiefly in the context of schizophrenia, are supported by the brain, drawing on MRI indices of neurodevelopment. I introduce the phenomenon of hallucinations …

The Measure and Meaning of Structural Similarity in the Brain
… structure. At the same time, recent advances in structural MRI analytics have enabled large-scale mapping of anatomical similarity within individual brains. However, key questions remain that limit the current applicability and interpretability of research using similarity mapping approaches. …
