We present a comparison of in-vivo connectivity scores: one derived from electrophysiology (EP) signals in human brains monitored with parenchymal electrodes (for epilepsy workup); and the other from imaging connectivity methods such as HARDI and resting state fMRI. Assuming EP represent a gold standard of connectivity, this provides a validation of various connectivity scores derived from MRI.
