Mean metric values within the precuneus region for both resting and task states.

Global mean metrics across all states were calculated for each subject and averaged as group means. Eglob, global efficiency; Eloc, local efficiency; K, average degree;(mean ± SD).针对每名被试，计算其在所有状态下的全局平均指标，再以组为单位求取组均值。其中Eglob代表全局效率（global efficiency），Eloc代表局部效率（local efficiency），K代表平均度（average degree），结果以均值±标准差（mean ± SD）表示。
