Functional Connectivity and Integration–Segregation Difference (ISD) Across Conditions. The cortex was parcellated into 400 regions using the Schaefer 400-parcel atlas and organized according to the Yeo seven-network parcellation, while the subcortex was defined by 56 regions from the Tian subcortical atlas. fMRI time series were extracted from all 456 regions of interest (ROIs). Pairwise Pearson correlation coefficients were Fisher z-transformed to generate functional connectivity matrices for each experimental condition. The ISD metric was calculated as the difference between integration and segregation, where integration was quantified by multi-level global efficiency and segregation by the multi-level clustering coefficient. Asterisks (*) indicate statistically significant differences after FDR correction (p < 0.05); hash marks (#) indicate uncorrected significance (p < 0.05); and n.s. denotes non-significant differences. Abbreviations: VIS = visual, SMN = somatomotor, DAN = dorsal attention, VAN = ventral attention, LIM = limbic, FPN = frontoparietal, DMN = default mode network, SUB = subcortical, LH = left hemisphere, RH = right hemisphere.
