Abstract :
Telemetry technology offers possibility to observe physiological activity of animals in a nature state. In this paper, 24 h physiologic signals of rats under different conditions were recorded. New indices for blood pressure evaluation were developed. Meanwhile, approaches to heart rate variability spectrum analysis, linear and non-linear analysis of electroencephalogram (EEG) were developed to estimate the activity of autonomic nervous system and central nervous system, respectively. The results demonstrate that the new parameters extracted from telemetry data may reveal more efficient information of physiological activity, which is impossible by conventional methods. The results also provide the evidence that the activity of central nervous system relates closely to the sympathovagal balance and the sympathetic activity
