“…This procedure has two advantages: (1) the inter-individual variability in estradiol and progesterone levels covers the whole range in hormone levels (from minimum to maximum); and (2) At first glance, dynamic changes in IHTT across the menstrual cycle are compatible with the hypothesis that sex hormone-mediated variations in FCA can be explained as hormone-modulated variations in the degree of interhemispheric coupling (Hausmann & Güntürkün, 2000). As discussed above, Hausmann and Güntürkün (2000) suggested that the increase in progesterone and/or estradiol (see Hausmann & Bayer, 2010 there is evidence that IHTT is directly related to the structural integrity of the corpus callosum (e.g. Westerhausen et al, 2006;Whitford et al, 2011), the extent to which interhemispheric inhibition and IHTT share the same transcallosal mechanisms needs further consideration.…”

“…However, sex differences in FCAs are not always found (e.g. Sommer, Aleman, Bouma, & Kahn, 2004), partly because sex hormonal factors have been largely ignored (Hausmann, 2010;Hausmann & Bayer, 2010). In fact, considerable evidence has accumulated that suggests that FCAs in women are modulated by fluctuations in gonadal steroid hormones across the menstrual cycle (e.g.…”

“…The original model by Hausmann and Güntürkün (2000) has been revised recently (Hausmann & Bayer, 2010) to take into account some new findings. The revised Hypothesis of Sex Hormone-Modulated Cortical Interaction differs from the original model in three main aspects.…”

“…For example, it has been shown that sex differences in FCAs partly depend on the cycle phase in which female participants were tested (e.g. Hausmann & Güntürkün, 2000;Hausmann, Becker, Gather, Güntürkün, 2002;Weis, Hausmann, Stoffers, Sturm, 2011;Weis, et al, 2008; for review see: Hausmann & Bayer, 2010). Specifically, the majority of these studies suggest that sex differences in hemispheric asymmetries do not exist (or are at least significantly reduced) when women were tested during the menstrual phase.…”

“…While lateralisation is stable in men, it fluctuates within relatively short time periods across the menstrual cycle in women (for a review, see Hausmann & Bayer, 2010). Indeed, a number of neuropsychological studies, across different modalities and cognitive processes, have demonstrated reduced lateralisation during cycle phases associated with high levels of estradiol during the follicular phase (e.g., Holländer et al, 2005;Weis et al, 2008) or high levels of both estradiol and progesterone during the luteal phase (e.g.…”

(2015) suggested that the effect was due to estradiol-related variations in bottom-up aspects of lateralisation. Method:The present study used two well-established left-and right-lateralised dichotic listening tasks (Hugdahl, 1995(Hugdahl, , 2003Grimshaw et al., 2003;, with forced-attention conditions to differentiate between these two ideas. Fifty-two naturally cycling women underwent both tasks, during either the menstrual, follicular or luteal cycle phase. Saliva estradiol and progesterone levels were determined by luminescence immunoassays. Results:The results showed that sex hormones did not affect language lateralisation, which may be due to the larger degree of lateralisation yielded by the task, compared to that shown by Hodgetts et al. (2015). In the emotional prosody task, high levels of estradiol were marginally associated with a reduction in cognitive control; while the language task yielded no cycle effects for either top-down or bottom-up processes. Conclusions:In sum, the current study revealed weak support for the idea that estradiol affects top-down control of lateralisation, as measured with dichotic listening tasks. Given that the task employed in the present study seemed less cognitively demanding than that used previously, it is suggested that estradiol-related inter-and intra-individual variations in lateralisation are small when task demands are low.
