Histograms from the bootstrap analyses of the difference in Spearman correlation of the imaginary component of the coherence (ICOH) during NREM sleep, using the T3-Cz electrode pair, and Bayley-III language scores, with and without maternal voice playback, for 32 infants (panel A: 4 to <8Hz; panel B: 8 to <12Hz; panel C: 12 to <16Hz; panel D: 16-30Hz). The vertical blue lines indicate the 2.5 and 97.5 percentile values. Differences in ICOH with and without maternal voice playback were greater for higher EEG frequencies.
