Default mode network (DMN). Two components were identified: Ant-DMN (A) and post-DMN (B). The anterior component included MPFC, anterior cingulate, hippocampal formation, and superior temporal and inferior parietal regions, whereas the posterior component encompassed PCC, precuneus, dorsal MFPC, and bilateral posterior parietal regions. One sample t test images display the spatial pattern of the ICs identified (P < .005 uncorrected). TC represents the temporal profile of DMN for each component (continuous line) overlaid on the paradigm of working memory design (dashed line). Color bar indicates T-scores.
