Fig. 3: Transient and nonlinear changes in periodic power between 12 and 35 Hz.
From: Developmental trajectories of EEG aperiodic and periodic components in children 2–44 months of age
a, b Individual periodic power spectra 6–8 months, and 18–20 months old. Red markers show peaks between 12 and 20 Hz. Green markers show peaks between 20 and 35 Hz. c Proportion of infants with peak identified between 12 and 20 Hz at each age bin, with shaded areas representing 95% confidence intervals. d–h GAMMS modeled trajectories for males (orange) and females (blue). Lines are the model predicted value with the shaded area representing 95% confidence intervals. Relative inflection points are shown with circular markers. Source data are provided as a Source Data file. Below, heatmaps show the standardized change in offset or slope per day, defined as [change per day]/[standard deviation of measures across full age range].
