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.
