GAY BRAS STCTURED LIKE THOSE OF THE OPPOSE SEX

Some physil attribut of the homosexual bra remble those found the oppose sex. The imag show the amygdala heterosexual men and women (labeled HeM and HeW) and homosexual and women (labeled HoM and HoW)(Image: Natnal Amy of Scienc, PNAS). Bra sns have provid the most pellg evince yet that beg gay or straight is a blogilly fixed tra.

The sns reveal that gay people, key stctur of the bra erng emotn, mood, anxiety and aggrsivens remble those straight people of the oppose sex. “This is the most robt measure so far of cerebral differenc between homosexual and heterosexual subjects, ” she says.

Prev studi have also shown differenc bra archecture and activy between gay and straight people, but most relied on people’s rpons to sexualy driven cu that uld have been learned, such as ratg the attractivens of male or female fac. First they ed MRI sns to fd out the overall volume and shap of bras a group of 90 volunteers nsistg of 25 heterosexuals and 20 homosexuals of each genr. The rults showed that straight men had asymmetric bras, wh the right hemisphere slightly larger – and the gay women also had this asymmetry.

BRAS OF GAY PEOPLE REMBLE THOSE OF STRAIGHT PEOPLE OF OPPOSE SEX

Gay men, meanwhile, had symmetril bras like those of straight women.

They found that the patterns of nnectivy gay men matched those of straight women, and vice versa (see image, above right). In straight women and gay men, the nnectns were maly to regns of the bra that manift fear as tense anxiety.

Gay men have higher rat of prsn too, she says, but ’s difficult to know whether this is down to blogy, homophobia or simply feelgs of beg “different”. “This study monstrat that homosexuals of both sex show strong cross-sex shifts bra symmetry, ” says Qazi Rahman, a leadg rearcher on sexual orientatn at Queen Mary llege, Universy of London, UK.

“Paradoxilly, ’s more rmative to look at thgs that have no direct nnectn wh sexual orientatn, and that’s where this study sr, ” says Simon LeVay, a proment US thor who 1991 reported fdg differenc (pdf) a part of the bra lled the hypothalam between straight and gay men.

ScienceNot Exactly Rocket ScienceThe differenc between heterosexual and homosexual people are as much the subject of fascatg science as they are a source of social bate. A new study adds new weight to this evince by g bra-snng technology to look at the differenc between the bras of gay and straight people. Their imag show that the bras of gay people, certa featur cludg symmetry and nnectns to the bra’s emotnal centre are more closely matched to the bras of straight people om the oppose sex.

SymmetryUsg magic ronance imagg (MRI), Savic and Ldstrom showed that the bra’s two halv are almost exactly the same size straight women and gay men. For example, parts of the bra volved reward and emotn are more strongly activated when straight men and lbian women look at female fac, and when straight women and gay men see male fac. But attractive fac and enticg pheromon are both related to sex, and rpons to them uld be learned over Savic’s and Ldstrom’s new study shows that the differenc extend to fundamental aspects of the bra that aren’t directly lked to sex or behavur, and that are probably fixed om ia that straight men have more asymmetril bras than gay men fs wh prev rearch.
