Table 1.
Positive correlations of fMRI BOLD signal with orthogonalized EEG-derived regressors early (time window starting 200 ms after stimulus onset and ending with the individual median RT) and late (time window starting 100 ms prior to RT and ending 300 ms after RT).

The region in which the cluster’s local maximum is located in hemispheres Right (R), Left (L), or Central (C); the peak location in MNI coordinates (x, y, z); cluster extend in number of voxels (k); maximum Z-score; and FWE-corrected p-values (cluster level corrected,
*
small volume corrected) are reported for each significantly activated cluster separately. IFG, inferior frontal cortex. SMA, supplementary motor area.
