rats in all frequencies in PCTX and all but beta in FCTX as compared to adult rats. Periadolescent humans were found to have significantly lower synchrony than adults as indexed by lower PLI levels in the delta and theta frequency ranges in all three electrode sites (FZ, CZ, PZ). Periadolescent humans had significantly lower PDLI levels (FZ-PZ) than adults in all frequency ranges. Periadolescent rats also had lower PLI values than adults in the alpha frequencies in PCTX, and lower PDLI levels than adults in the theta, alpha, and beta frequency ranges. Taken together these findings are consistent with the hypothesis that adolescent remodeling of the brain includes decreases in energy and increases in synchrony over a wide frequency range both within and between neuronal networks and that these effects are conserved over evolution.
