n this resting state study, we examined the effect of the menstrual cycle on six major functional brain networks as well as the hippocampus and amygdala, regions which may play an important role in spatial cognition and emotion processing throughout the menstrual cycle. We utilized 160 meta-analysis derived ROIs to parcellate the cortex and cerebellum into six networks: cingulo-opercular, frontoparietal, default mode, sensorimotor, occipital, and cerebellar. It was observed that the inter-regional correlations among some of these networks as well as the hippocampus and amygdala were differentially modulated during phases of the menstrual cycle.
