EEG recording was performed in healthy women during various phases of menstrual cycle. Comparative study showed that the power spectrum of EEG a-waves in central and medio-temporal areas significantly decreases during ovulation. In the menstrual phase coherent characteristics of EEG alpha-waves increased in symmetrical occipital and intrahemispheric parieto-occipital areas.

UI MeSH Term Description Entries
D008597 Menstrual Cycle The period from onset of one menstrual bleeding (MENSTRUATION) to the next in an ovulating woman or female primate. The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.
