Sometimes it can seem as though boys' and girls' brains are hardwired differently. One reason may be the way their brains are packed into their skulls, suggests a new study. A team of neuroscientists Many famous neuroscientists are from the 20th and 21st century, as neuroscience is a fairly new science. However many anatomists, physiologist, and physicians are considered to be neuroscientists as well. (brain scientists) from the University of California The University of California has a combined student body of more than 191,000 students, over 1,340,000 living alumni, and a combined systemwide and campus endowment of just over $7.3 billion (8th largest in the United States). at Los Angeles Los Angeles (lôs ăn`jələs, lŏs, ăn`jəlēz'), city (1990 pop. 3,485,398), seat of Los Angeles co., S Calif.; inc. 1850. wanted to find out if male and female brains work differently. So they used a special tool to create 3-D images of the brains of 30 males and 30 females. It turns out, certain areas of the female brain have more folds than the same areas in the male brain. "[The extra folds] may contribute to behavior differences in men and women," says lead researcher Eileen Luders. Or, since many females have smaller bodies than males, it might just be nature's way of fitting the same brain mass into a smaller head, she adds. This could help explain why even though males tend to have bigger heads than females, they're not necessarily smarter. Think about it.
