This abstract focus on finding comprehensive set of measures of functional connectivity in order to improve the localization of the seizure focus in temporal lobe epilepsy patients. The measurement includes resting state functional connectivity, regional homogeneity, amplitude of low frequency fluctuation, fractional amplitude of low frequency fluctuation and voxel-mirrored homotopic connectivity. We have found that, not only the whole brain hippocampal functional connectivity, but also other high level features of resting state fMRI signal, such as regional homogeneity, amplitude of low frequency fluctuation differ between left and right temporal lobe epilepsy groups. These results can be incorporated in pattern classification methods as prior knowledge to increase the classification accuracy.
