Reproducibility of oxy-Hb-based functional network properties over time.

<p>The mean correlation matrices derived from sub-dataset 1 (A) and sub-dataset 1 (B) are highly similar to each other (C). The regional nodal metrics also exhibited strong correlations between the two sub-datasets (D) over a wide range of sparsity thresholds (degree: r = 0.79±0.06; efficiency: r = 0.81±0.08; and betweenness: r = 0.68±0.14). These results suggest a high reproducibility of fNIRS-based brain network metrics over time.
