摘要: All night sleep EEG from ten normal students were subjected to FFT spectral analyses. Delta (0.3-3 Hz), sigma (12-16 Hz) and beta (20-28 showed strongly oscillating patterns across the night. The scattergram of versus revealed two separate clusters. One cluster demonstrated a positive linear correlation between beta. second range beta, but stable, low level activity. Points in former consisted those NREM epochs, latter, REM epochs. present results suggest that are composed sets frequency components, perhaps reflecting different neuronal pools.
