Abstract
Monopolar recordings of the EEG during sleep from each occipital area in normal volunteers indicated a consistent prevalence of spindles over the right hemisphere and more pronounced slow wave activity over the left. Asymmetry in the slow wave activity was confirmed by an analysis of the secondary components of the visually evoked potentials. The data indicated that the hemisphere generally considered to be “subdominant” during the awake state is subject to less intense non-REM sleep, suggesting a reversal in the “dominance” of hemispheres in sleep.
