Abstract: The group level PCC FC and ACC FCs (Fig. 1c and d, Fig. 2c and d) were similar to those repeatedly reported in the literatures (Fox and Raichle, 2007; Margulies et al., 2007). CBF vs PCC-FC correlations were found in orbitofrontal cortex (OFC), visual cortex, PCC/precuneus, bilateral parietal cortex (PA), and left dorsal lateral prefrontal cortex (DLPFC) at both scan sessions (Fig. 1a and b). Most of these posoitive correlated voxels are in the significant PCC FC regions shown in Fig. 1c and d. Correlations in other brain regions were not repeated in the retest session. No significant CBF correlations were found for vACC FCs using the 3 vACC ROIs. CBF vs dACC-FC correlations were consistently demonstrated in bilateral prefrontal cortex in both sessions (Fig. 2a and b). These regions were in the significant dACC FC regions as shown in Fig. 2c and d. No significant correlation was found between global CBF and the FCs.
