Statistical shape analysis of neuroanatomical structures based on spherical wavelet transformation
… multi-scale shape models and study the localized cortical folding variations in a normal population using Principal Component Analysis (PCA). We then build a shape-based classification framework for detecting pathological changes of cortical surfaces using advanced classification methods, such as …

Magnetic resonance imaging and surface-based analysis techniques to quantify growth of the developing brain
… gyrencephalic: folded) to accommodate a large cortical surface within the limited volume of the skull. Abnormal folding of the cerebral cortex in humans is associated with a number of neurological dysfunctions and diseases such as schizophrenia and Williams syndrome. To understand the mechanism …

ADDUCINS AFFECT CORTICAL NEUROGENESIS BY REGULATING PROGENITORS¿ MORPHOLOGY AND FATE
… reason for this change can be found during neocortical development in an increased neuronal production during a prolonged neurogenic period. Neocortical development starts during embryogenesis with the main neural progenitor cells, classified as apical (APs) and basal progenitors (BPs). BPs are …

The Brains of Babies: A Surface Based Approach To Study Cortical Development in Term and Preterm Human Infants
… that we improve our understanding of normal cortical development and develop tools to evaluate injury. Using a surface based approach we have characterized normal cortical development in healthy term infants and analyzed abnormalities associated with preterm birth. Accurate cortical surface …

Network Dynamics of Visual Object Recognition
… transient interactions between the disseminated cortical substrates within category-specific networks. Employing novel techniques for the topologically accurate and statistically robust analysis of grouped icEEG, we found that category-selective regions were spatially arranged with respect to …

Neurobiological mechanisms of hallucinations in schizophrenia
… matter reductions, I turn to the contribution of cortical sulcation, a product of second and third trimester neurodevelopmental processes, which has been robustly implicated in schizophrenia pathology, and, more recently, in hallucinations. Sulcal patterns derived from structural MRI provide a …

Effects of HIV and different anti-retroviral therapy (ART) regimes on brain structure in HIV infected children at age 7
… (http://freesurfer.net/) to generate measures of cortical thickness, local gyrification index (LGI), and regional (corpus callosum, bilateral caudate, hippocampus, putamen, thalamus, and lateral ventricle) and global brain volumes. Vertex-wise and region of interest (ROI) comparisons were …
