Abstract：To explain how the brain differences between men and women affect people's thinking and behavior, we made an quanti-tative analysis for the brain differences between the sexes based on DTI complex network technology.44 cases of healthy volunteers were divided into female group and male group.The data were collected by magnetic resonance diffusion tensor imaging scan.The differences of brain structural between the sexes and their corresponding functional manifestation were analyzed by constructing brain structure network based on white matter fiber and using graph theory and the characteristics parameters of complex networks.Both groups showed small-world property.There were significant gender differences in the brain regions involved in language, emotional, motor skills and orientation.The brain structural differences between the sexes does lead to the functional difference.The brain func-tional differences between sexes can be thought to be caused by the brain regions difference responsible for related functions.
