FIGURE 4.

Statistical differences of frequency-specific FCD between two groups. (A) Statistical differences of S-FCD between two groups in three frequency-specific bands. (B) Statistical differences of L-FCD between two groups in three frequency-specific bands. The color bar indicates the t-values, which represent increased (warm) and decreased (cool) S-FCD and L-FCD in the GAD patients compared with HCs. Two sample t-test, significant level was set at P < 0.05, with AlphaSim corrected. The left hemisphere is on the left.
