Reproducibility of oxy-Hb-based functional network properties across subjects.

<p>The mean correlation matrices derived from subgroup 1 (A) and subgroup 2 (B) are highly similar to each other (C). The regional nodal metrics also exhibited strong correlations between the two subgroups (D) over a wide range of sparsity thresholds (degree: r = 0.56±0.14; efficiency: r = 0.57±0.16; and betweenness: r = 0.57±0.20). These results suggest a high reproducibility of fNIRS-based brain network metrics across subjects.
