It is intriguing to explore the relationship among different connectivity measures in the brain. The current study compared the volume based connectivity and functional connectivity from 152 (volume based dataset) and 42 (functional dataset) rats, and revealed significant correlation between those two connectivity measures. Although both connectivity measures were negatively correlated with physical distances between ROIs, their robust correlation still remains after regression of physical distances.
