ReHo values in bilateral sensorimotor cortex across participants: mean value (standard deviation) in different conditions of ‘Slow vs. Rest’.

aCont: Contralateral hemisphere to the tapping finger (Left hemisphere);
bIpsi: Ipsilateral hemisphere to the tapping finger (Right hemisphere);
cSD: Standard deviation;
dDiff: ReHo Difference in each ROI between ‘Slow’ and ‘Rest’ states. The difference value was first calculated within subject and then averaged across subjects.
We made cubic region of interests (ROIs) (27 voxels) in bilateral primary sensorimotor cortex (PSMC). The bilateral peak voxels in different conditions, which showed significant difference in ‘Slow vs. Rest’ (Figure 2), were picked as center for cubic ROIs. For each participant, the mean ReHo value of each mask for ‘Slow’, ‘Rest’ and ‘Tonic’ states, as well as difference ReHo value between ‘Slow’ and ‘Rest’ states (Diff) were calculated. The group mean values and standard deviations were then calculated across subjects as showed in the table.

aCont：与敲击手指对侧的大脑半球（左侧大脑半球）；
bIpsi：与敲击手指同侧的大脑半球（右侧大脑半球）；
cSD：标准差（Standard deviation）；
dDiff：“慢节律”与“静息”状态下各感兴趣区（Region of Interest, ROI）的局部一致性（Regional Homogeneity, ReHo）差异值。该差异值首先在个体层面计算，随后跨被试取平均。
我们在双侧初级感觉运动皮层（Primary Sensorimotor Cortex, PSMC）内构建了立方体状感兴趣区，每个ROI包含27个体素。将不同任务条件下在“慢节律vs.静息”状态下存在显著差异的双侧峰值体素（见图2）作为各立方体ROI的中心。
针对每名被试，我们分别计算了“慢节律”“静息”与“紧张性”三种状态下各掩膜的平均ReHo值，以及“慢节律”与“静息”状态间的ReHo差异值（即Diff）。随后跨被试计算组平均值与标准差，结果如表中所示。
