[The normal E.E.G. of the neonate (author's transl)]

This study is the statement of the present knowledge of the normal EEG activity of the full term and the premature neonates. The criteria for normality of the records are based on transversal studies of normal newborn babies, born after a normal pregnancy and a normal delivery (Apgar 9 and 10). Follow up studies of children over of period of 3 years or more have allowed to appreciate the variability of the neonatal EEG, especially in premature babies having a later normal psycho-motor development. The variability of bioelectric activity is considerable from child to child and in the same child from one moment to another especially during quiet sleep. EEG activity varies according to the states of vigilance and sleep. Organisation of sleep is independent of the recording methods, as shown by a comparative study using different technics of electrode application.
