As mentioned before, the correlation matrices of ΔHbO2, ΔHb and ΔtHb were obtained from fOT data to analyze the connection properties between male and female groups. In this study, the ΔtHb was chose to perform the hemispheric functional connectivity analysis. Figure 6 demonstrates the functional connectivity patterns (group-level correlation network) of left-side and right-side PFC regions in resting-state of male (Fig. 6(a)) and female (Fig. 6(b)) groups. The functional connectivity were identified as the values of correction coefficients greater than 0.6. In the results, 203 lines (left-side: 102 lines, right-side: 101 lines) and 139 lines (left-side: 68 lines, right-side: 71 lines) brain functional connectivity of PFC were presented in male and female groups, respectively.
