combined with the difference between intramodal and intermodal correlation trajectories suggest a significant divergence in developmental pattern between the auditory and visual systems from age 16 to age 20 followed by a reconvergence. (We note the somewhat anomalous behavior of intramodal visual Cz – Pz and intermodal auditory Fz – visual Cz). Differences between male and female trajectories were small compared to those in the power trajectories.
