Fig. 7

Girls with Rett syndrome demonstrate a significantly more negative 1/ƒ slope of the power spectrum when compared to typically developing controls. a The slope of the power spectrum was calculated and compared between girls with RTT and TD controls (top panel) as well as among TD controls, girls with RTT in active regression (AR), and girls with RTT that are postregression (PR) (bottom panel). b For girls with RTT, Spearman’s rho correlations (with fitted line) were utilized to relate slope to performance on the Mullen Scales of Early Learning (MSEL) in the receptive language, visual reception, fine motor, and expressive language domains (clockwise from top left).
