Brains Show Differences by Gender, Study Says

Differences between the sexes in the way the brain works may make men more inclined to fight and women to talk, researchers have found.
In a study in the current issue of the journal Science, University of Pennsylvania researchers also reported evidence of sex-linked differences in brain areas controlling verbal skills and those governing spatial abilities such as map reading, or motor control.
"These findings support the possibility that men are more biologically inclined to instrumental means of expression - such as physical aggression - while women are more biologically inclined to symbolic expression," said the study's author, Dr. Ruben Gur.
In an interview, Gur said, ". . . The interesting part is linking well-known behavior to differences in brain function." Gur directs the university's Brain Behavior Laboratory and is a professor of psychology and psychiatry.
The study supports earlier research finding statistical differences in behavior between men and women, and suggests this may be so because of the way the brain works, Gur said.
Although much of the brain's structure and function is thought to be inherited, effects of upbringing and other environmental factors on how the brain works cannot be ruled out, Gur said. …
