Discovery - Evolutionarily 'Preserved' Gender Signature In The Primate Brain
Researchers have determined that there are hundreds of biological differences between the sexes when it comes to gene expression in the cerebral cortex of humans and other primates. These findings indicate that some of these differences arose a very long time ago and have been preserved through evolution. These conserved differences constitute a signature of sex differences in the brain. Many more obvious gender differences have been preserved throughout primate evolution; examples include average body size and weight, and genitalia design. This study, believed to be the first of its kind, focuses on gene expression within the cerebral cortex. The cerebral cortex is involved in many of the more complex functions in both humans and other primates, including memory, attentiveness, thought processes and language. read more
