At the same time, powerful new brain imaging technology and sophisticated animal studies provided scientists with tools to map human emotions and gender differences.ĭue to this revolutionary technology, we now know that areas for emotional memory and communication are larger in the female brain, perhaps explaining why, on average, women remember fights that men insist never happened, and why women use 20,000 words a day, while men use only 7,000.Īt puberty, there is again an explosion of hormones, according to Brizedine. But in the '90s, the government began requiring that all its studies include women. But it has really been ignored until probably the middle '90s."įor years, brain studies focused primarily on male subjects. Adult men and adult women act differently, too. Of course, little boys and little girls act differently. "And they may just be able to negotiate the sharing better than boys. "The reason little girls may play better together is brain wiring - verbal ability at a younger age," she continued. Boys don't hear the complete tones in the female voice." The girls would hear their mom's voice, turn around, look at their mom's face, and stop. "The boys would just go right for the object and touch it. "The studies that were done with children around 12 months old where their moms went in a room with them and they were told not to touch an object," recounts Dr. While the behavioral effect of all of this remains a mystery, conjectures have been made. From six to nine months, a boy's testicles are flooded with adult levels of testosterone. Incredibly, during the first two years of life a baby girl's ovaries will pump adult levels of estrogen. Recent studies reveal that after birth girls are already better at reading faces and hearing human vocal tones. It is only after a surge of testosterone that boys' brains begin to look male. Brizendine says that after eight weeks in utero all children's brains appear exactly the same: female.
