Hemispheric specialization varies with EEG brain resting states and phase of menstrual cycle.

Interestingly, post-hoc simple comparisons of each phase of the menstrual cycle also revealed that emotional word advantage was significantly greater in LVF than RVF during the menstruation phase ( F (1, 9) = 7.8611, p = .02), marginally significant during the follicular phase (F(1, 9) = 5.8, p = .04) and not significant during the early, mid- and late luteal phases ( p >.05).
