Document Summary
Sex differences in the brain parts: planum temporale. Have been studies to look at if the planum temporale is different between genders: results show that women tend to be more likely to show reverse pattern (right bigger than left) Meta-analytical study done on about 13 studies showed there actually weren"t any sex related differences in terms of laterality. One study showed that women usually have areas larger which are involved in language production and comprehension. Size of callosum compared showed that it was larger in men. But the splenium (posterior end) of the callosum in women tended to have a different shape (more bulbous) This meta-analysis says the shape of the splenium doesn"t differ between sexes. Most meta-analytic assessments show that focal regions sex difference studies do not really provide any definitive results. Are sex differences in verbal abilities related to sex differences in degree of brain lateralization of verbal abilities: the results say no.
