The functional lateralization of the brain was modulated by the menstrual cycle of women, while the mechanism of which still need to investigate.In this study, we used interhemispheric functional connectivity of the resting-state functional MRI to investigate changes in the symmetrical interhemispheric correlations in women’s different menstrual phases. Our results showed that the brainstem and cerebellum had significantly higher interhemispheric correlations in the early follicular phase than in the mid-luteal phase.
