There are four significant findings regarding the development of theta EROs in adolescents and young adults reported in this study: Male and female developmental trajectories of theta ERO power were significantly different in their temporal characteristics, with more rapid decreases with age in males than in females during the ages of 12 to 25. The change in the rate of decrease with age was nearly monotonic in males, with greater fluctuations in females.Male and female developmental trajectories of power were not significantly different in their regional characteristics. Relations between power at different locations were similar between males and females and the shapes of trajectories did not depend on location.Both males and females exhibited increasing supraregional (global) functional integration with age in each modality as manifested by increasing intramodal power correlations, with correlations between more distant locations showing the greatest proportional increase over the course of the ages of 12 to 25. Intramodal correlations were always larger than intermodal correlations.Both males and females exhibited a decrease followed by a sharp increase in supramodal functional integration in a span centered at age
