Cumulative distribution of resting times in human motor activity.

<p>Double logarithmic plots represent (panels a, c) cumulative distribution of rest periods as a function of duration time and (panels b, d) cumulative distribution of rescaled rest periods as a function of rescaled duration time for all RW subjects (black symbols) and all SD (red symbols). Here, stands for the individual mean of rest period duration. Each curve corresponds to one of six consecutive days. Continuous lines show slopes of the fitted power-laws. Top panels (5+16) mode; bottom panels (16+5)mode. The threshold separating state of activity versus rest .
