Fig. 1.

Illustration of data from one neonate with normal MRI (top row of panels) and one neonate with abnormal MRI (bottom row of panels). (a & e) Examples of simultaneously recorded 20-hour aEEG (in μV) and SctO2 (in %) tracings with a sampling rate of 0.21 Hz. (b & f) Continuous wavelet transform (CWT) of the corresponding tracings from (a) and (e), where y-axes represent the scale in minute and the color gradient represents the amplitude of power after CWT. (c & g) Time-scale coherence maps of NVC of the selected infants; x-axis in all panels represents time in hour; y-axes represent scale in minute; color gradient scale indicates the amplitude of WTC coherence, R². The areas with significant NVC (p < 0.05) are red. (d & h) T1 weighted axial brain MRI slices obtained on day 5 of life. Arrows in (h) indicate the basal ganglia abnormalities consistent with HIE.
