Conductivity mapping of a human brain is important to enhance accuracy of EEG or MEG source localization in brain function studies. In this study, we have experimentally shown cross-property relation among electrical conductivity, diffusion, and T2, using a silk yarn phantom which mimics neuronal tissues. It has been observed that the electrical conductivity, diffusion, and T2 are strongly correlated among them and all the three physical constants are strongly dependent on the compartmental structure of biological tissues. We think that electrical conductivity of biological tissues can be estimated from their diffusion and T2 values measured with MRI.
