Menstrual Cycle Modulation of Verbal Performance and Hemispheric Asymmetry.

ABSTRACT: Background/Objectives: It has been postulated that sex differences in certain types of verbal abilities arise from sex-dimorphic patterns of hemispheric activation, and that these patterns might be modulated by circulating levels of sex hormones. The aim of this study was to explore the activational effects of sex hormones (throughout the menstrual cycle) on both verbal performance and functional hemispheric asymmetries (qEEG laterality) in three types of verbal tasks: sex-differentiated (verbal fluency and semantic decision) vs. sex-neutral (verbal reasoning) tasks. Methods: A group (n = 32) of healthy young women was tested twice, once during the mid-luteal (high levels of circulating sex hormones) and once during the early follicular (low levels of sex hormones) pha
