Sex on the brain

Gene that helps determine gender linked to Parkinson's disease.

Biologists have proof that men do, in fact, have sex on the brain. A crucial sex-determining gene on the male Y chromosome, called Sry, is known to be expressed in the male brain as well as in the testes.

i think that is a very interesting piece of information. Would it potentially be responsible for better motor movements and spatial information, as men seem to have better spatial infomation than women? A lot of inetersting traits could be studied with this information in hand.

Sex on the Brain is a chatty, fairly evenhanded report on a broad range of animal and human studies intended to provide insight into hot-button issues such as aggression, nurturing behavior, infidelity, homosexuality, hormonal drives, and sexual signals. According to one researcher "We inherit the behavior essentially of our past." Morning sickness, for example, which steers some women away from strong tastes and smells, may once have protected babes in utero from toxic items. Infidelity is a way for men to ensure genetic immortality. Interestingly, when we deliberately change sex-role behavior--say men become more nurturing or women more aggressive--our hormones and even our brains respond by changing, too.
