Mean accuracy values ± standard deviation for different fMRI extra active area’s amplitude when the whole fMRI signal and high spatial frequencies of fMRI are considered as prior for EEG source localization with p-value <0.05.

Accuracy evaluates a method for identifying true activation. A higher value of the Accuracy means better identification of the sources. The third column of the table represents the accuracy improvement percentage, comparing the fMRI and SIMF-based EEG source localization.
