While all human brains consist of the same material—about 40 percent gray matter and 60 percent white matter—the brain of a man is significantly different from that of a woman From studies conducted using intelligence tests, it has been determined that men use nearly seven times more gray matter than women do, whereas womenuse nine times more white matter than men do The main functions of gray matter seem to lie in the disciplines ofspatial awareness, including map-reading, mathematics and problem-solving, whereas white matter connects the processing centers of the brain and is important in the use of language, emotional thinking and the ability to do more than one thing at once.
Because women use more white brain matter, they tend to be better communicators In fact, the female brain has a greater number of areas associated with communicationthan the male brain does, which explains why women tend to use language as an emotional rapport-building device whereas men use language to exchange information andsolve problems On average, a woman says 7,000 words per day while a man says only 2,000
The two hemispheres of the female brain are also linked more effectively than those of the male brain, and they re more closely connected, which explains how women arebetter able to multi task than men, who generally have to concentrate on one job at a time This greater connectivity in the female brain is also thought to be the reason for socalledwomen’s intuition
These differences are thought to have been brought about by the social roles adopted by men and women in our ancestors’ time Men, for instance, would go out hunting,often tracking their prey for many days, which required problem-solving and navigation, whereas women neededto be more emotionally and linguistically attuned to protect their home and offspring In fact, studies show that women with higher than average levels of the male hormone testosteronetend to be able to read maps more effectively than other women
