12 sessions of EEG activity, one every second day, were recorded at F3, F4, C3, C4, P3, P4, O1 and O2 in 9 women with regular menstrual cycles. The following significant oscillations were observed: 1) absolute power was lower during periovulatory period; 2) absolute power of delta theta and alpha 1 was higher during premenstrual period whereas absolute power of alpha 2, beta 1 and beta 2 was higher during menstruation; 3) relative power of low alpha frequencies was lower and that of high frequencies was higher during premenstrual period; 4) interhemispheric correlation between frontals was higher during ovulation and between occipitals was higher during premenstrual phase; 5) no significant power asymmetries were observed. The present findings suggest higher activation of centro-parietal regions during menstruation and lower activation of frontal regions during premenstrual phase.
对9名月经周期规律的女性，每隔一天记录一次，共记录12次脑电图活动，记录部位为F3、F4、C3、C4、P3、P4、O1和O2。观察到以下显著振荡：1）排卵期绝对功率较低；2）经前期δ波、θ波和α1波的绝对功率较高，而月经期α2波、β1波和β2波的绝对功率较高；3）经前期低α频率的相对功率较低，高频率的相对功率较高；4）排卵期额叶半球间相关性较高，经前期枕叶半球间相关性较高；5）未观察到明显的功率不对称。目前的研究结果表明，月经期间中央顶叶区域激活较高，经前期额叶区域激活较低。
