| Abstract: | Objective：A regional homogeneity approach was applied to investigate the hemispheric asymmetries of regional function patterns.Materials and Methods：We recorded continuous fMRI data for six minutes from 21 undergraduates at resting-state.Results：The right hemisphere showed significantly greater regional coordination strength than the right hemisphere in inferior frontal gyrus and inferior parietal lobule.In contrast,the left hemisphere was stronger than the right in superior temporal gyrus and cuneus.Conclusion：It is not a consistent hemispheric asymmetry in brain function patterns.Most of right hemisphere areas have higher regional coordination than the left to processing cognitive function,but the lower at occipital areas. |
