Central 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 ...

Prematurity and prenatal growth restriction differently affects brain connectivity at age 6 years.

Jean-Philippe Thiran, Elda Fischi Gomez, Reto Meuli, Patric Hagmann, Djalel Eddine Meskaldji, Leila Cammoun, François Lazeyras

Survival of children born prematurely or with very low birth weight has increased dramatically but the long term developmental outcome remains a concern with many children having deficits in their cognitive capacities, in particular involving executive dom ...

A 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 ...

Spatial analysis of karst conduit networks and determination of parameters controlling the speleogenesis along preferential lithostratigraphic horizons

Marco Filipponi

The main objective of this thesis is to improve the understanding of the position and characteristics of karst conduits within a rock massif. Such a characterisation is an important issue in civil engineering and in hydrogeology. Today in practice dissolut ...

Brain Surface Segmentation of Magnetic Resonance Images of the Fetus

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer, Dominique Zosso, Nawal Houhou, Damien Ferrario

In this work we present a method for the image analysis of Magnetic Resonance Imaging (MRI) of fetuses. Our goal is to segment the brain surface from multiple volumes (axial, coronal and sagittal acquisitions) of a fetus. To this end we propose a two-step ...

Immunocytochemical expression of monocarboxylate transporters in the human visual cortex at midgestation

Pierre Magistretti, Maxime Olivier Baud, Luc Pellerin

Lactate and the other monocarboxylates are a major energy source for the developing brain. We investigated the immunocytochemical expression of two monocarboxylate transporters, MCT1 and MCT2, in the human visual cortex between 13 and 26 post-ovulatory wee ...

PPARgamma/RXRalpha heterodimers control human trophoblast invasion

Johan Auwerx, Kristina Schoonjans

The ligand-dependent nuclear receptors PPARgamma and RXRalpha/beta were recently determined to be essential for murine placental development and trophoblast differentiation. In the current study we examined the expression and role of the PPARgamma/RXRalpha ...

Structural Brain Network Reorganization and Social Cognition Related to Adverse Perinatal Condition from Infancy to Early Adolescence

Jean-Philippe Thiran, Elda Fischi Gomez

Adverse conditions during fetal life have been associated to both structural and functional changes in neurodevelopment from the neonatal period to adolescence. In this study, connectomics was used to assess the evolution of brain networks from infancy to ...
