Neurulation and the cortical tractor model for epithelial folding
Development, 1986ABSTRACT We present here a new model for epithelial morphogenesis, which we call the ‘cortical tractor model’. This model assumes that the motile activities of epithelial cells are similar to those of mesenchymal cells, with the added constraint that the cells in an epithelial sheet remain attached at their apical circumference.

A geometric model for the cortical folding pattern of simple folded brains
Journal of Theoretical Biology, 1982Abstract A model for the folding of the cerebral cortex is described which effects a direct link between the geometry of the brain and its folding pattern. Using some simple approximations to the brain's geometry the model is able to predict folding patterns.

Cortical Folding: When, Where, How, and Why?
Annual Review of Neuroscience, 2015Why the cerebral cortex folds in some mammals but not in others has long fascinated and mystified neurobiologists. Over the past century—especially the past decade—researchers have used theory and experiment to support different folding mechanisms such as tissue buckling from mechanical stress, axon tethering, localized proliferation, and external ...

Evidence for alterations of cortical folding in anorexia nervosa
European Archives of Psychiatry and Clinical Neuroscience, 2015Anorexia nervosa (AN) is highly heritable, and the perspective on the etiology of AN has changed from a behavioral to a neurobiological and neurodevelopmental view. However, cortical folding as an important marker for deviations in brain development has yet rarely been explored in AN. Hence, in order to determine potential cortical folding alterations,

A Biomechanical Model of Cortical Folding
2015A principal characteristic of the geometry of the brain is its folding pattern which is composed of gyri (outward hills) and sulci (inward valleys). We present a preliminary two-dimensional biomechanical model of cortical folding that is implemented computationally using finite elements. This model uses mechanical properties such as stress, strain, and

Shape analysis of cortical folds
2011The cortical surface in humans is comprised of several folds which are juxtaposed together to form a biologically meaningful pattern. For many biological reasons, the geometry of this pattern changes in time: folds get longer, wider and deeper. The relationship between the shape of cortical folds and biological factors such as gender and aging can be ...

Cortical folding and the evolution of the human brain
Journal of Human Evolution, 1993Abstract The degree of cortical folding can be measured by the gyrification index (GI) and has undergone a previous comparative analysis. In this paper the ontogenetic features of cortical folding that are of interest for an analysis of human brain evolution are examined.
