Significant Clusters in the Voxel-Wise Two-Sample t-test Comparing Functional Connectivity of the Default-Mode Network in Heroin Users (HU) versus Controls (CN).

a. Coordinates in Talairach space (Left to Right, Posterior to Anterior, Inferior to Superior).b. Within-group mean-values and standard deviations of z-scores for each cluster; for each participant, the z-score for each cluster was calculated by averaging z-scores of all voxels in that cluster. BA = Brodmann's Area, ACC = anterior cingulate cortex.a. 塔莱拉什空间（Talairach space）内的坐标，轴方向依次为左至右、后至前、下至上。b. 各簇的z分数的组内均值与标准差；针对每名被试，其对应簇的z分数通过计算该簇内所有体素的z分数的平均值得到。其中，BA为布罗德曼分区（Brodmann's Area），ACC为前扣带回皮层（anterior cingulate cortex）。
