Changes in cortico-cortical functional connectivity as a function of birth gestational age. a The main effect of group shows higher long-range connectivity in the alpha band in EP infants compared with HC. The corresponding widespread network is composed of temporal (green), central (pink), occipital (black), and frontal (orange) cortices (pFWER < 0.0001, paired two-tailed t-test). b The line shows the distribution (kernel density estimate) of functional connections lengths, where p is the fraction of edges (normalized to the whole network). Bar plots show participation of broad cortical areas in each sleep-related network. c Spectral fingerprints of EP (left) and HC (right) infants. Colors show the effect size (Cohen’s d) of group contrasts for all combinations of carrier vs. amplitude frequencies (f). Darkest blue shade marks the cases where there were no suprathreshold edges (null)
