Abstract

Visually-scored, non-Rapid Eye Movement (REM) sleep electroencephalographic (EEG) waveform activity for each 30-s sleep scored epochincluding the number of sleep spindles, the number of K-complexes, and the percentage of delta waves occupying the epochwas correlated with H215O positron emission tomography. Sleep spindle correlations included positive correlations in the thalamus and right hippocampus. K-complex correlations included positive correlations in the frontomedian prefrontal cortex and cerebellum. Delta wave correlations included negative correlations in the thalamus, frontomedian prefrontal cortex, dorsal pons, and primary visual cortex. Each pattern of correlations may suggest a functional significance for these waveforms that relates to a waking outcome.
