[Mechanisms of forming and working reproductive dominant]

Spectral and coherent analyses of biolectrical brain activity in gestational dynamics and in early post-natal period has been made at 560 pregnant women and at 35 women during menstrual cycle. The encephalography (EEG) examination of 184 women participating in the program in vitro fertilization (IVF) has been carried out. According to the theory and the experiments, it can be concluded that the occurance of one-foetus pregnancy is accompanied by the forming ofgestational dominant-constellation of nervous centres. Its central chains are located in limbico- diencephal and neocortical structures. Neocortical representation is formed within frontal and central areas of the hemisphere, that is contralatteral to the placenta replacement. Some electrographical phenomena have been found out and they is experimently prove this ideas. It is supposed, that one of the ways of increasing of efficacy of the IVF methods is the investigation of the mechanisms of central-peripheral integration in women's reproductive system.
