A EEG amplitudes modulation in frequencies 1–40 Hz as a function of time. B The amplitude modulation of the spindle band (14–18 Hz) across time for physical activity (red line) and rest (blue line). Shaded areas represent the standard error of the mean across subjects. The gray shading indicates the interval displaying significant differences between rest and PA. Time 0 represents stimulus onset.
