Fig. 1

Results of ASL functional connectivity analysis (group-level analysis). The results of the group analysis (2nd level analysis) are shown in the table, where the presence or absence of functional connectivity between regions is indicated by color (p < 0.05 analysis-level FDR correction). The numbers in the table represent t-values. The red colors indicate significant positive functional connectivity, the blue colors indicate significant negative functional connectivity, and the color intensity reflects the strength of the functional connectivity. The uncolored areas indicate no significant functional connectivity. See Table 1 for abbreviations of ROIs. TAS-20 = The 20-item Toronto Alexithymia Scale; DMN = default mode network; SN = salience network; CEN = central executive network; FDR = false discovery rate; ROI = region of interest
