Regional age-related differences in power.

(A) Regional age-related decreases in delta band power. (B) Regional age-related increases in beta band power. Scatter plots contain summed regional age effect (beta weight from Power × Age model) as a function of the region’s anatomical y-coordinate center of mass. (C) Power × Age anatomical gradient as a function of frequency. Error bars represent standard error of the model fit. Red shaded bar denotes delta and beta band regimes from panels A and B. y-Axis represents the beta weight (slope) of the relationship between power and age with the anatomical y-coordinate of the region’s center of mass. See S1 Data for individual data points.
