American researchers found females are the more talkative sex because of a special "language protein" in the brain.

The study,conducted by neuroscientists (神经学家) and psy?chologist from the University of Maryland,concluded that women talked more because they had more of the FoxP2 protein. The research,published in The Journal of Neuroscience,found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previ?ously claimed that ladies speak about 20,000 words a day―over 13,000 more than men. "This study is one of the first to report a sex difference in the expression of a languageassociated protein in humans or animals," said Professor Margaret Mc?Carthy,who led the study. In their study,the researchers attempted to determine what might make male rats more vocal than their female friends.

They separated four-day-old rats from their mothers and then counted the number of times they cried out in the "ultrasonic (超声波的) range", the frequen?cies higher than humans can hear,over five minutes. While both sexes called out hundreds of cries,the males called out twice as often,they found. But when the pups were returned to their mother's cage,she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocal calls showed the male pups had up to twice as much FoxP2 protein as the females. The research?ers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast,males became less talkative.

The researchers then tested samples from ten children,aged between three and five,which showed that females had up to 30 per cent more of the FoxP2 pro?tein than males,in a brain area key to language in humans.

"Based on our observations,we assume higher levels of FoxP2 in girls and higher levels of FoxP2 in male rats is an indication that FoxP2 protein levels are as?sociated with the more communicative sex," said Professor McCarthy.

"Our results imply FoxP2 as a component (成分) of the neurobiological basis of sex differences in vocal communication in mammals."
