While it is obvious that nonlinear mechanisms are crucial in neural systems, there has been strong criticism of attempts to identify at strange attractors in brain signals and to measure their fractal dimensions, Lyapunov exponents, etc. Conventional methods analyzing brain dynamics are largely based on linear models and on Fourier spectra. Regardless of the existence of strange attractors in brain activity, the neurosciences should benefit greatly from alternative methods that have been developed in recent years for the analysis of nonlinear and chaotic behavior Notes "The workshop was organized by the John von Neumann Institute for Computing (NIC) at the Forschungszentrum Jülich and the Department of Epileptology of the Bonn University Medical Center"--Preface Bibliography Includes bibliographical references Notes Print version record Subject Electroencephalography -- Congresses Chaotic behavior in systems -- Congresses Brain -- Mathematical models -- Congresses Time-series analysis -- Congresses Nonlinear theories -- Congresses Electroencephalography.
