DMN-SN intra-network connectivity correlations with psychological state. The improved CES-D depression score (negative change marks improvement in the depression score for the post vs. pre assessment) was correlated with increased negative internetwork DMN-SN rsFC. Additionally, the improved MHC_SF, general mental Health score (positive change marks improvement), was correlated with increased negative internetwork DMN-SN rsFC. This suggests a correlation between the extent to which individuals improved in their psychological state and the extent in which their connectivity pattern became healthier.
