Associations of endogenous 17-β-estradiol with theta amplitude and performance in semantic categorization in young women.
Bottom Line: We identified parameters associated or not associated with menstrual cycle phases.Irrespective of the menstrual cycle phase, women (1) responded faster to living items as well as to nouns characterized by many features compared to non-living items and items characterized by few features, (2) showed higher accuracy to non-living items and items having many features, and (3) showed negative correlation between response time (RT) and theta amplitude.RT, accuracy and post-stimulus theta amplitude were not statistically significantly different among early follicular, late follicular or luteal women.

Mentions: Raw EEG was filtered in the theta frequency band and post-stimulus theta amplitude was quantified. Women were segregated in fast and slow responders by a median split. Women responding fast to nouns showed a significantly larger theta amplitude compared to women responding slowly to nouns (Fig. 1). Especially for non-living items, we observed significant correlations between RTs and theta amplitude in early follicular, late follicular and luteal women (Table 3). Furthermore we found significant correlations between accuracy and theta amplitude but only in early follicular and luteal phases for non-living items.
