Graph theory reveals dysconnected hubs in 22q11DS and altered nodal efficiency in patients with hallucinations
Jean-Philippe Thiran, Leila Cammoun, Marie Schaer
Schizophrenia is postulated to be the prototypical dysconnection disorder, in which hallucinations are the core symptom. Due to high heterogeneity in methodology across studies and the clinical phenotype, it remains unclear whether the structural brain dys ...
Frontiers Research Foundation2013How to Measure Cortical Folding from MR Images: a Step-by-Step Tutorial to Compute Local Gyrification Index
Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer
Cortical folding (gyrification) is determined during the first months of life, so that adverse events occurring during this period leave traces that will be identifiable at any age. As recently reviewed by Mangin and colleagues2, several methods exist to q ...
2012Central and Cortical Gray Mater Segmentation of Magnetic Resonance Images of the Fetal Brain
Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer, Gabriele Vincenzo Bonanno, Anouk André
Motivation. The study of human brain development in its early stage is today possible thanks to in vivo fetal magnetic resonance imaging (MRI) techniques. A quantitative analysis of fetal cortical surface represents a new approach which can be used as a ma ...
2010A post-processing pipeline to reconstruct the developing fetal brain using low-resolution MRI
Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer
Introduction. Development of the fetal brain surface with concomitant gyrification is one of the major maturational processes of the human brain. First delineated by postmortem studies or by ultrasound, MRI has recently become a powerful tool for studying ...
2010Prefrontal Plasticity and Stress Inoculation-Induced Resilience
Coping with mild early life stress tends to make subsequent coping efforts more effective and therefore more likely to be used as a means of arousal regulation and resilience. Here we show that this developmental learning-like process of stress inoculation ...
2009Smaller Global and Regional Cortical Volume in Combat-Related Posttraumatic Stress Disorder
Context Two sets of findings predict smaller cerebral cortical gray matter volume in adult posttraumatic stress disorder (PTSD). Measures of intracranial tissue volume and cerebral tissue volume have been observed to be smaller in adolescents with maltreat ...
2009Congenital heart disease affects local gyrification in 22q11.2 deletion syndrome
Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer
22q11.2 deletion syndrome (22q11.2DS) is a common genetic condition associated with cognitive and learning impairments. In this study, we applied a threedimensional method for quantifying gyrification at thousands of points over the cortical surface to ima ...
