Relationship between autonomic nervous system activity and chaotic attractor on biological signal

Describes the effect of autonomic nervous activity on heart rate variability and peripheral blood pressure with power spectral analysis and its characteristics of chaotic attractors. The authors' aim is to access the applicability of spectral and dimensional analysis of biological signals, attributed to changes in autonomic nervous system activity. Heart rates and peripheral blood pressure were recorded while various mental and physical conditions. Spectral and dimensional analysis of experimental data are processed. The results show the availability to evaluate the autonomic nervous activities and some mental and physical failures.
