Associations of endogenous 17-β-estradiol with theta amplitude and performance in semantic categorization in young women.

Brötzner CP, Klimesch W, Kerschbaum HH - Neuroscience (2014)

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.

Illustration of cortical theta oscillations in response to non-living NOF− items. (A) Woman showing the shortest latency in response to a noun (red) and woman showing the longest latency in response to a noun (black). (B) Average of theta oscillations of women with shortest (below median split of RTs) (red) and longest (above the median split) latencies. Line at 0 ms indicates onset of noun presentation. ERP, event-related potential. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)

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.
