Both males and females exhibit a general decrease in theta ERO power from ages 12 to 25. Pervasive differences between male and female growth patterns during this age range are the most striking feature of our results. (See Figure 1). In contrast to the decrease in power with age, the correlations between the power values increased from age 12 to age 25 for correlations within each modality between locations (intramodal), and increased from some age between 17 and 20 to age 25 for correlations between modalities at both the same and different locations (intermodal), with the trajectories of intramodal correlations having a different pattern than the trajectories of the intermodal correlations. The differences between males and females in the trajectories of the correlations of the power values is much less than in the trajectories of the power values themselves.
