Figure 4.

State engagement variability trajectories plotted by sex using data from the MLS datasets. The smoothed curve was generated using the Locally Weighted Least Square Regression technique in R’s ggplot2 package. Activation patterns associated with each brain state are again shown above the trajectories. Across all four brain states, state engagement variability increased with age before reaching its peak in adolescence. Plotting trajectories by group additionally indicated that female participants appeared to reach a stabilization point before male participants.
