In recent years, it has been pointed out that it is important to consider the menstrual cycle (sex hormones) when examining neurophysiological sex differences. It has been reported that estrogen (especially estradiol: E2) and progesterone (P4) play a major role in the female menstrual cycle and influence human brain function. However, very few studies have examined neurophysiological sex differences in terms of the menstrual cycle. Therefore, the purpose of this study is to investigate the effects of sex differences in menstrual cycle (especially menstrual and ovulatory phases) on late brain activity (after 100 ms after stimulus presentation) in humans, and to clarify sex differences in higher-level brain function. We will also provide evidence that it is important to consider menstrual cycle (sex hormones) and sex differences when examining neurophysiological sex differences.
Safety,Efficacy
In order to investigate the effect of sex difference on late brain activity (after 100 ms of stimulus presentation), we record somatosensory evoked potentials (SEPs) and auditory evoked potentials (AEPs) during simple response and resting conditions using electroencephalogram (EEG) and evaluate the sex difference. In this process, women are measured in two periods: the menstrual period and the ovulatory period. The menstrual period is defined as the period from the second to the fourth day after the onset of menstruation, and the ovulatory period is defined as the period from the second to the fourth day after a positive urine ovulation test. This allows for detailed clarification of sex differences in higher-order brain function. It also provides evidence that it is important to consider the menstrual cycle (sex hormones) and sex differences when examining neurophysiological sex differences.
