Abstract

The aim of this paper is to report on a new attempt at characterizing the electroencephalogram (EEG), which is based on recent progress in the theory of nonlinear dynamical systems (Brandstäter et al. 1983; Nicolis and Nicolis 1984, 1986; Babloyantz et al. 1985). The method is independent of any modeling of brain activity. It relies solely on the analysis of data obtained from a single-variable time series. From such a “one-dimensional” view of the system, one reconstructs the {X k} (where k = 1,..., n) variables necessary for the description of systems dynamics. With the help of these variables, phase-space trajectories are drawn. Provided that the dynamics of the system can be reduced to a set of deterministic laws, the system reaches in time a state of permanent regime. This fact is reflected by the convergence of families of phase trajectories toward a subset of the phase space. This invariant subset is called an “attractor.”
