Physiological Signals and Their Fractal Response to Stress Conditions, Environmental Changes and Neurodegenerative Diseases; Conference paper

摘要

During the last decades nonlinear system theory has been widely applied to the analysis of biomedical time series and given rise to what is known as nonlinear and fractal physiology. Some of these studies have been intended to develop more reliable methodologies for understanding how biological systems respond to peculiar altered conditions induced by internal stress, environment stress and/or disease. Herein, we show some of our results regarding the fractal dependency on different conditions of physiological signals such as inter-breath intervals, heart inter-beat intervals and human stride intervals.
