A polygraphic study of bioelectrical brain maturation in preterm infants / Renate NOLTE in Developmental Medicine & Child Neurology, 20-2 (April 1978)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 20-2 (April 1978) . - p.167-182 Titre : A polygraphic study of bioelectrical brain maturation in preterm infants Type de document : Texte imprimé et/ou numérique Auteurs : Renate NOLTE, Auteur ; Gerhard HAAS, Auteur Année de publication : 1978 Article en page(s) : p.167-182 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Bioelectrical brain maturation was studied in 26 low-risk preterm infants by serial polygraphic recordings. A modified method of visual EEG analysis was used, based on Parmelee's coding system, which allowed quantification. It gave the following results: (1) The main characteristics of EEG maturation in preterm infants were a progressive spatio-temporal differentiation, with an increase of rhythmic activities and a decrease of discontinuity. (2) A strong relationship was found between post-menstrual age of the infants and EEG maturity, but there were exceptions to this rule. (3) longer duration of extra-uterine life had a small accelerating influence on EEG maturation. (4) Certain basic types of EEG patterns were closely related to behavioural states, whereas EEG maturity was not state-dependent. (5) The relationship between EEG pattern types and behavioural states becomes more stable with increasing age.
