    cut with a butter knife. From the outside‚ the brain’s most distinguishing features are its convolutions‚ or folds. These wrinkles are part of the cerebral cortex (Latin for “bark” or “rind”). The cerebral cortex is the orange-peel thick outer covering to maximize surface area (more cells per square inch). In fact‚ if it were laid out‚ the cortex would be about the size of an unfolded single page from a daily newspaper. Yet it is only a grapefruit-sized organ. Its importance can be attributed to

    matter (GM)‚ increases in the myelination of cortico-cortical connections and changes in the architecture of large-scale cortical networks. It is currently unclear‚ however‚ how the ongoing developmental processes impact upon the folding of the cerebral cortex and how changes in gyrification relate to maturation of GM/WM-volume‚ thickness and surface area. In the current study‚ we acquired high-resolution (3 Tesla) magnetic resonance imaging (MRI) data from 79 healthy subjects (34 males and 45 females)
