The second and third column describe respectively the location of the epileptogenic region and the number of interictal epileptiform discharges (IED) that were identified in the EEG recorded during fMRI scanning. Presented in the fourth till sixth column are the fractions of activated brain voxels resulting from the analysis when VIPH was a predictor (frac${}_{\text{stan}}^{\text{VIPH}}$), when the IED were correlated to BOLD (frac${}_{\text{stan}}^{\text{IED}}$) and when VIPH was added as confounder (frac${}_{\text{VIPH}}^{\text{IED}}$) to the GLM. Column 7 shows the difference between the results of the correlation analyses with and without VIPH taken into account. Column 8 depicts the overlapping ratios as specified in Eq. (4). The last column indicates the localization of the maximal BOLD response present in the overlapping area of these two models. DNET, Dysembryoplastic neuroepithelial tumor; RF, right frontal lobe; RT, right temporal lobe; LT, left temporal lobe.
