Evolutionary difference of brain of male and female.

The difference between male and female brain is age old mystery. Recently CT,MRI and especially PET and fMRI and other brain mapping studies, it was found that the gender differences in brain were far from just expected. As the major difference between male and female is reproductive system,there is expected differences reproductive system in representation in brain.especially in hypothalamus and limbic system. The reviews the differences are beyond that due evolutionary functional role the gender play. The most signifying differences are in language and communication area i.e. Wernick’ and Braca’ areas of brain, Prefrontal lobe, inferior parietal lobules, Straight gyrus,amygdale, pain perception and oxytocin mediated stress responses. Though certain facts generate controversy more research will give better high light understanding the gender differences of brain structure and function.
