Abstract

Spectral and coherent analyses of bioelectrical activity of the brain of 560 pregnant women during gestation and the early postnatal period and 35 women during a menstrual cycle were carried out. The EEG examination of 184 women participating in the in vitro fertilization (IVF) program was carried out. The conclusion that one-fetus pregnancy is accompanied by the formation of the gestational dominant, a constellation of nerve centers, whose central components are located in the limbic-diencephalic and neocortical structures, is substantiated theoretically and experimentally. The neocortical representation is formed within the anterior (temporal and frontal) and central regions of the hemisphere contralateral to the side of the placenta’s location. The electrographic phenomena that are direct experimental proofs of these phenomena were identified. It is suggested that the study of the mechanisms of central-peripheral integration in the female reproduction system is one of the ways of increasing the effectiveness of the IVF method.
