Abstract :
The authors investigated the autonomic nervous activity during sleep stages by means of power spectrum density of heart rate variability signal. Spectral estimation was performed by autoregressive modelling of RR series. The data obtained suggest an augmented sympathetic activity during REM sleep and a progressive decrease of it when passing from awake state to stages 1,2,3-4
