Brain sex differences hemispheric specialization and listening in Eastbourne

The lateralization of short-range connectivity was stronger for males than for females rightward lateralizedwhereas lateralization of long-range connectivity was stronger in some regions for females leftward and in others for males rightward.

Studies based on seed regions of interest ROIs distributed uniformly in the brain reported a small but significant gender by laterality interaction effect on the strength of the functional connectivity stronger in males than in females between seed regions Liu et al.

There was no significant correlation between handedness as a continuous variable and net scores on brain sex differences hemispheric specialization and listening in Eastbourne and punishment IGT.

Human Brain Mapping. It was hypothesized that strong right-handedness motor lateralizationaffect or valence-directed task instructions lateralized motivationand a punishment frame of the IGT affect lateralization would facilitate advantageous IGT decision-making, such that the overall more-lateralized male sex would benefit more from lateralized constructs.

Another limitation of the study is that motor lateralization in terms of degree of handedness was not balanced in terms of sex, as noted in the literature: the left-handed population is largely male Oldfield,

Sex differences in the effects of unilateral brain damage on intelligence. Both males and females differentiated between the 4 deck choices of the reward IGT; however, only females benefited from valence-directed task instructions by choosing more from the advantageous decks.

Compared to other cognitive control tasks e. Thus, the valence-directedness of task motivation could generate strong lateralization and might reveal sex-differences. A meta-analysis of volume differences found a higher HCV in males without correcting for total brain size. Benton, A.

The ideas of differences between the male and female brain have circulated since the time of Ancient Greek philosophers around BC. It was hypothesized that strong right-handedness motor lateralization , affect or valence-directed task instructions lateralized motivation , and a punishment frame of the IGT affect lateralization would facilitate advantageous IGT decision-making, such that the overall more-lateralized male sex would benefit more from lateralized constructs.

Future studies should specifically aim at ascertaining right-lateralization of IGT decision-making in healthy adults, and should ensure inclusion of a gender-balanced left- and mixed-handed sample. J Neurosci Res.
