In this paper, we acquired in vivo DTI data in order to quantitatively map the axons connected to the cerebral cortices in humans, chimpanzees, and macaque monkeys and applied in-house software tools ( Liu et al.

Thanks to recent technical developments, diffusion tensor imaging (DTI) is now able to quantitatively map axonal fiber connections ( Mori 2006), and DTI-derived fiber tracts are well correlated with axon densities ( Mori et al. In this paper, based on quantitative analysis of macroscale neuroimaging data and microscale microscopic bioimaging data, we present a novel axonal pushing theory of cortical folding. However, due to a lack of joint and quantitative mapping between axonal wiring patterns and gyral and sulcal formations, the underlying mechanisms guiding these processes remain unclear. Therefore, at the conceptual level, it is reasonable to postulate that there is a close relationship between cortical folding and axonal wiring. Among many factors ( Barron 1950 Rakic 1988 Welker 1990 Sur and Rubenstein 2005) that play important roles in complex cortical folding, the axonal wiring process is believed to be a critical determinant ( O’Leary 1989 Van Essen 1997). Neuroscience research has demonstrated that the neural structures of gyri and sulci emerge from complex cortical folding processes during development ( Rakic 1988).
