We consider the signal compression problem in the peripheral nervous system. We propose a simple mechanism by which the narrow dynamical range observed experimentally in isolated sensory neurons translates into a wide dynamical range as a result of excitable waves and synchronization phenomena which provides self-limited amplification. The mechanism is(More)
Multifractal analysis of heart rate variability (HRV) has been used to discriminate healthy subjects from patients with severe health conditions. We analyzed the fractal structures of the ECG recording of 11 patients who suffered acute myocardial infarction in order to identify those with impaired Left Ventricular Ejection Fraction (LVEF). Was estimated the(More)
There are many different tools and parameter that can be used to analyze RR time series, as the Correlation Dimension, the Lyapunov Exponents, the Higher Reconstruction Step. Here we address the problem of discriminating between two populations: one with some cardiac disease and another with healthy people, in a no invasive way, through RR time series. The(More)
