Abstract

The complexities exhibited by biological systems are highly intriguing. Their activity can span both micro and macroscopic scales simultaneously. Often noise plays an important role. So, the analysis of the dynamical properties of such systems poses a major challenge. In this paper we introduce an approach that is applicable within both the micro and macroscopic worlds, where a large number of oscillators acting on a similar time scale can be represented as an ensemble that, on the macroscopic scale, may be taken as a single oscillator. On the macroscopic scale they interact with other similar type of oscillators, but usually on widely different time scales. We use recently introduced nonlinear dynamics methods and methods derived from information theory, and extend their application to oscillations acting on micro and macroscopic scales at the same time. We demonstrate such interactions using numerical examples and real physiological data related to cardiac, respiratory and brain activities.
