From: Narrow band quantitative and multivariate electroencephalogram analysis of peri-adolescent period
Fractions of low frequencies/high frequencies in three different scalp locations. The fractions of Low delta (8A) and Delta-Theta (B) Spectral Power are represented. Notice that the fractions of low delta did not have a difference between age groups, while those of delta-theta present a higher value in children than in adults indicating the dramatic decrease of delta-theta power in the adolescent period.
