Using resting state fMRI for individual brain mapping in preneurosurgical planning is discussed. The purpose of our study was to compare the localization of eloquent cortex (motor, speech and executive areas) obtained from resting state fMRI (rsfMRI) and from task based fMRI (tbfMRI). The average percent of overlap of motor areas obtained by the two fMRI methods was appreciable (median 41 - 70), but the overlap revealed for speech and executive areas was very small (median 0 - 23). A significant correlation was revealed between the laterality indexes obtained from tbfMRI and seed-based analysis of rsfMRI. The substantial inter-individual variability in overlap for areas of eloquent cortex mapped by the two different fMRI methods appeals to the necessity of verification of rsfMRI data by direct cortical electrostimulation before using this method in routine clinical applications.
