    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...

    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...

    ..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...
