The variability found in physiological signals was initially considered noise. Later, it was realized that there was meaning in this noise. Even more astonishing is that the phenomenon of variability that we find in physiological signals is found widely in nature. It can be said that the events we find in physiological (and natural) behaviors are not equal, but neither are they independent. The Theory of Dynamic Systems and Chaos has served as a support to explain these events over time and what is their connection with health. Events over time constitute temporal series whose structure contains precious meaning about motor and physiological behavior. This seminar aims to show how this meaning is highly associated with variability over time.

Luís Miguel Domingues Ferreira Silva is a postdoctoral researcher at the Department of Physics at the Faculty of Science and Technology at Universidade NOVA de Lisboa, and is a member of the Laboratory for Instrumentation, Biomedical Engineering and Radiation Physics (LIBPhys). Previously, he was a postdoctoral researcher at the Department of Biomechanics at the University of Nebraska, USA and did his PhD in Human Motricity at the Faculty of Human Motricity at the University of Lisbon. His research interests focus on the interpretation of the physiological meaning of biosignals and their relationship with human behavior using the construction of processing algorithms and artificial intelligence.
