Fractal dimension in human cortical surface: multiple regression analysis with cortical thickness, sulcal depth, and folding area.


Fractal dimension (FD) has been widely used to provide a quantitative description of structural complexity in the cerebral cortex. FD is an extremely compact measure of shape complexity, condensing all details into a single numeric value. We interpreted the variation of the FD in the cortical surface of normal controls through multiple regression analysis… (More)
