Eugene Stanley (BU | | Abstract: | We propose a general approach to the question of how biological rhythms spontaneously self-regulate, based on the concept of ``stochastic feedback’’. We illustrate this approach by considering the neuroautonomic regulation of the heart rate. The model generates complex dynamics and successfully accounts for key characteristics of cardiac variability, including the $1/f$ power spectrum, the functional form and scaling of the distribution of variations, and correlations in the Fourier phases. Our results suggest that in healthy systems the control mechanisms operate to drive the system away from extreme values while not allowing it to settle down to a constant output. | | Source: | arXiv, cond-mat/9710325 | | Services: | Forum | Review | PDF | Favorites | |
