Sigma (12-16 Hz) and beta (20-28 Hz) EEG discriminate NREM and REM sleep.

Abstract

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 Hz) EEG showed strongly oscillating patterns across the night. The scattergram of sigma versus beta revealed two separate clusters. One cluster demonstrated a positive linear correlation between sigma and beta. The second cluster showed a range of beta, but a stable, low level of sigma activity. Points in the former cluster consisted of those from NREM epochs, and in the latter, from REM epochs. The present results suggest that REM and NREM EEG are composed of two sets of EEG frequency components, perhaps reflecting different neuronal pools.
