The literature on changes in human sleep patterns with age was recently reviewed in detail (Feinberg, 1976). One of the sleep variables most sensitive to age is the amplitude of the electroencephalogram (EEG), especially that of the phase of sleep characterized by dense, high-voltage slow (delta) waves (stages 3 & 4 in the Dement and Kleitman (1957) classification system). Here we shall present hitherto unpublished data which illustrate the increase in EEG amplitude during infancy and its decline during adolescence, the periods of most rapid change. In addition, we shall show that these and other effects of age on delta activity during sleep can be detected by computer analysis during periods of much slower change, even when the analysis is restricted to a narrow age range.
