Fig. 5: Main effects of age on late alpha/beta oscillatory dynamics.

(middle): Whole-brain statistical maps showing the significant main effects of age in the late alpha/beta window. Scatterplots display the associations between age and the strength of neural oscillations at the peak voxel in the left dorsomedial prefrontal cortex (dmPFC; top left), left sensorimotor cortex (bottom left), right sensorimotor cortex (top right), and right cerebellum (bottom right) collapsed across the three expressions. Pseudo-t values with the number of trials per condition regressed out are displayed on the y-axis and age in years on the x-axis. Shaded areas around regression lines indicate 95% confidence intervals. To enhance visualization (i.e., data spread), data points that were >3 SD from the mean were excluded from the scatterplots. Note that all data were included in the statistical analyses and that the results remained the same regardless of including/excluding these data.
