Fig 3. Scheme of the power-spectral density (PSD) of inter-beat interval (IBI) time series.

Fig 3

A. The combination of a long-range correlated clock and motor process (dashed lines) superpose to a V-shaped PSD of the IBIs (solid line). The characteristic frequency (or time scale, see upper axis) at the minimum determines the turnover between the clock-dominated and motor-dominated regime. B. Same as panel A, but assuming that both, the clock and motor process are uncorrelated. C. Sketch of genre-induced differences in the PSD.
