Regions of significant activity related to working memory load.
List of significant clusters for load comparisons (averaged over task) for encoding, maintenance and retrieval. Standardized Montreal Neurological Institute (MNI) co-ordinates represent peak maxima of significant clusters (family-wise error (FWE)-corrected threshold). Approximate Brodmann areas are listed.
*Hippocampus cluster was significant upon ROI analysis. Threshold was applied voxel-wise (FWE-corrected) to the region identified with a bilateral hippocampal mask defined using Wake Forest University Pick Atlas.
