(A, B) Examples of ripples detected in the scalp EEG that passed visual validation. Histograms of (C) ripple amplitude, (D) ripple duration, and (E) ripple peak frequency. Vertical lines indicate the median across all sleep stages. (F) Spatial distribution of ripple densities for participants >4 months old. The area of each circle is proportional to the density for that bipolar channel pair. (G) Global ripple densities per sleep stage for each participant. Participants are listed in order by increasing age. (H) Boxplots of global ripple densities across all participants <4 months old (left) and > 4 months old (right). The boxplots were generated using data points corresponding to the average value for each participant. (* indicates P-value < 0.05, all P-values are corrected for multiple comparisons using the Bonferroni method).
