(A) Group-averaged correlation maps (using a t-SPM scale) of voxels showing correlation with the PCC seed. (B) Statistically significant anti-correlations were observed between the Task-Positive Network and the Default Mode Network by applying a multiple comparisons corrected threshold of t=5.17 following the regression of either the GAS or the PC-based global effect estimator. The anti-correlations obtained following the regression of the PC-based global effect estimator were less extended than those obtained by regression the GAS. PCC, posterior cingulate cortex.
