Abstract
We discuss multiple-time scale properties of neurophysiological contro l mechanisms, using heart rate and gait regulation as model systems. W e find that scaling exponents can be used as prognostic indicators. Fu rthermore, detection of more subtle degradation of scaling properties may provide a novel early warning system in subjects with a variety of pathologies including those at high risk of sudden death.
