Abstract
Sleep electroencephalograms (EEG) of healthy male subjects were analyzed by the correlation dimension. The mean correlation dimensions significantly d ecreased from stage 'awake' to stages 1, 2 and 3 and increased during rapid eye movement sleep. The mean correlation dimensions of the sleep EEG in th e second half of the night were significantly higher than those in the firs t half of the night. These significant changes were also seen during sleep stage 2.
