Characteristics of spontaneous bioelectrical activity of the brain in women with normal gestation and gestosis.

摘要

Pregnant women were examined during I, II, and III trimesters in order to detect EEG correlations of gestation dominant in health and threatened abortion. Single uncomplicated pregnancy was characterized by predominant activation in the central and temporal areas contralateral to the location of the placenta. Threatened abortion was associated with inversion of interhemispheric asymmetry of activation with respect to the placenta location.
