[Rhythmic alpha/theta bursts in the electroencephalogram of early premature infants: (2). Correlation with background EEG activity].
Rhythmic alpha/theta bursts were studied on ninety-five electroencephalographic records of early premature infants, ranging from 25 to 30 weeks of conceptional ages in relation with background EEG activity. When background EEG showed normal, frontal alpha bursts and occipital theta bursts were prominent at 25-26 weeks, and temporal theta bursts at 27-28 weeks. A significant decrease in all rhythmic bursts on the frontal, temporal and occipital areas, was seen in early premature infants showing severe background EEG depression. Incidence of rhythmic alpha/theta bursts varies inversely with depression of background EEG activity.
