Differences in the functional connectivity of the regions with altered ALFF value between HD and NC (p<0.01, AlphaSim corrected, T>2.7633 or <−2.7633, cluster>16).

Notes: X, Y, Z: coordinates in the Talairach-Tournoux atlas. BA: Broadmann area. L, R: Left and right. T values from the t-test of a peak voxel (showing the greatest statistical differences within a cluster), a positive T value indicates increased functional connectivity in heroin dependent individuals.
