- Identification of growth seeds in the neonate brain through surfacic Helmholtz decompositionJulien Lefevre
LNAO, Neurospin, CEA, Saclay, France
Inf Process Med Imaging 21:252-63. 2009..We show the reproducibility of such growth seeds across 4 neonates and make a link of this new concept to the "sulcal roots" one proposed to explain the variability of human brain anatomy...
- Larger is twistier: spectral analysis of gyrification (SPANGY) applied to adult brain size polymorphismDavid Germanaud
UMR663, INSERM Université Paris Descartes, Paris, France
Neuroimage 63:1257-72. 2012..Hence, we demonstrate that large brains are twistier than smaller ones because of an increased number of high spatial frequency folds, ramifications and kinks that accommodate the allometric increase of cortical surface...
- Optical flow approaches to the identification of brain dynamicsJulien Lefevre
NeuroSpin Center, Atomic Energy Commission CEA, Saclay, France
Hum Brain Mapp 30:1887-97. 2009..Local dynamic features from a variety of brain systems may also be explored through this methodology, as illustrated by experimental data on fast responses in the visual system as revealed by MEEG source imaging...
