[The encephalogram in women during pregnancy and in the postpartum period].
The EEG registration during gestation and after delivery in fifteen women was done. The EEG analysis has shown the alpha-rhythm amplitude and frequency fluctuation during pregnancy and maximum of power spectra in third trimester. After delivery, a general decrease in alpha rhythm was observed. In addition, general decay of the brain functional state occurred which was manifested by paroxysmal activity in hyperventilation in some women. The results are discussed from the point of view of the central regulation of hormonal state in women during pregnancy and after deliver.
