Localization and statistics of the peak voxels for the main effect of load (ROI analyses).

Note. Threshold of < 0.05 (FWE-corrected according to SPM8, small volume correction). indicates results surviving a Bonferroni-correction for the set of ROIs ( < 0.005). All coordinates () are given in MNI space. DLPFC = dorsolateral prefrontal cortex; VLPFC = ventrolateral prefrontal cortex; aPFC = anterior prefrontal cortex; ROI = region of interest; BA = Brodmann area; L = left; R = right.
