To determine if intra- and extra-DMN parietal regions belonged to different resting state functional networks, we formed five seed ROIs (radius = 6mm), centered on the peaks of memory search-related activations on the left hemisphere, corresponding to the Angular Gyrus (AG), the Posterior Cingulate Cortex-Precuneus (PCC-PreCu), the anterior Intraparietal Sulcus (aIPS), the Postcentral Sulcus (PoCS) and the Posterior Parahippocampal Gyrus (pParaHC). Corrected group voxelwise maps were created for each seed using the same procedure described above. In addition, we calculated the significance of rs-fcMRI between pairs of seed regions. For each subject, the correlation coefficient between the two regional time courses was computed and the Fisher z-transform was applied. A cross-correlation matrix was created showing the group averaged correlation coefficient of any given pair of seed regions. Significant correlation between pairs of seed regions was assessed using a 1-sample t-test on the Fisher z-transformed values from the individual subjects.
