a The cross-channel Δ[HbD] coherence from two individual neonates: one unaffected (normal MRI no lesions under the NIRS sensors) versus one affected (regional MRI area affected under the NIRS sensor). b Grand-averaged hemodynamic coherence spectrum from the unaffected pairs and the affected pairs (solid lines: mean; shaded areas: standard error). c Mean coherence (averaged locally over s = 200–300 s) was used to compare the unaffected pairs and affected pairs. The Wilcoxon’s test suggests statistical significance in the group comparisons between the affected pairs and unaffected pairs (p = 0.03).
