BRAS DIFFERENT GAY, STRAIGHT PEOPLE

Is there such a thg as a "gay bra"? And, if so, are some people born wh bras that make them more likely to be homosexual? Or do the bras... * gay straight brain differences *

Those are some of the thorny qutns raised by a new study that found strikg differenc between the bras of homosexuals and heterosexuals both men and women. “This rearch is potg to basic differenc the bra between homosexual and heterosexual people that are likely there right om the begng, ” said Sandra Welson, a profsor of psychiatry and behavral nroscienc at McMaster Universy Ontar.

In 1991, bra scientist Simon LeVay reported that the hypothalam, which is volved sexual behavr, tend to be smaller gay men.

STUDY SAYS BRAS OF GAY MEN AND WOMEN ARE SIAR

Other rearchers subsequently showed the bras of gay and straight people appeared likely to rpond differently to sexual imag. The rearchers who nducted the new study prevly reported that the bras of gay and straight men seemed to react differently to spected pheromon — odors thought to be volved sexual aroal. So Savic and her lleague, Per Ldstrom, first ed magic-ronance imagg, or MRI, to pare the symmetry of the bras of 25 straight men and 25 straight women wh those of 20 gay men and 20 gay women.

Gay men tend to have bras that were more like those of straight women than of straight men — the right and left sis were about the same size, the rearchers found. Gay women’s bras tend to be more like those of straight men than of straight women — the right si tend to be slightly larger than the left. Aga they found that gay men tend to be more like straight women, wh a stronger lk between the amygdala and regns volved emotns.

LeVay and other rearchers said the fdgs f wh studi that found gay people tend to have different rats the lengths of their fgers and the equency of imperceptible clickg sounds the ear. “There’s this clter of terrelated fdgs, ” said Richard Lippa, a profsor of psychology at California State Universy, Fullerton, who has found evince that gay men, the hair on the back of the head is more likely to curl unterclockwise than straight men. The fdgs also f wh studi showg gay men tend to choose profsns that typilly attract women, such as teachg and social work and have verbal and other gnive skills that tend to be more like women’s, he said.

“You get a sort of global shift genr tras gay people and straight people that affects not only their sexual orientatn but other thgs as well, ” LeVay said. Scientists at the Stockholm Bra Instute Swen report the Proceedgs of the Natnal Amy of Scienc USA that gay men and straight women share siar tras—most notably the size of their bras and the activy of the amygdala—an area of the bra tied to emotn, anxiety and aggrsn. Prev studi have examed bra differenc between gay and straight people on the basis of their rpons to var tasks, such as ratg the attractivens of other people.

The rearchers ed MRIs to terme the volume and shap of the bras of 90 volunteers—25 straight and 20 gay members of each sex.

They found that the straight men and gay women had asymmetril bras; that is, the cerebm (the largt part of the bra, which is rponsible for thought, sensory procsg, movement and planng) was larger on the right hemisphere of the bra than on the left. They found that gay men and women, the blood flowed to areas volved fear and anxiety, whereas straight men and lbians tend to flow to pockets lked to aggrsn. 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.

WHAT THE GAY BRA LOOKS LIKE

* gay straight brain differences *

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.

GAY BRAS STCTURED LIKE THOSE OF 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.

They also tend to outperform gay men and straight women tts of spatial awarens, where succs pends on a part of the bra – the parietal rtex – which is ually larger men than women.

From prev studi, we know that the nnectns ually lk to different areas the bras of men and women, and sprout om different hemispher -the right men, and the left was the pattern that Savic and Ldstrom saw the straight volunteers om their study, but the homosexuals showed the reverse pattern. For example, the amygdalas of gay men had more mon wh those of straight women – the two halv were well-nnected, they had more nrons projectg om the left half (as opposed to the right straight men) and the nrons nnected to the same parts of the bra that those of straight women nnectns provi some tantalisg hts about how gay and straight people differ their behavur.

GAY MEN, STRAIGHT WOMEN HAVE SIAR BRAS

Certaly, gay men, social stigma is an equally likely explanatn for higher rat of ’s very likely that the relative size of the bra’s two halv are set very early velopment. In animals, homosexualy femal is often attributed to an overabundance of male hormon – androgens – the womb, while male homosexualy rults om a lack of the. For stance, early studi reported an almost two-fold volumetric crease of the suprachiasmatic nucls of the hypothalam16 but twice smaller volum of the third terstial nucls of the anterr hypothalam (INAH-3) homosexual (HoM) relative to heterosexual men (HeM) and no volumetric differenc the INAH-3 between heterosexual women (HeW) and HoM17.

Comparg the regnal rtil thickns and subrtil volum of heterosexual and homosexual mal revealed smaller thalam volum and thner right orboontal and right visual rtic HoM20. In another voxel-based morphometry (VBM) study on sexual orientatn, ls gray matter nsy was observed the ventral cerebellum, the left ventral premotor rtex, and the temporo-basal rtex homosexual relative to heterosexual women22. Furthermore, homosexualy seems to be associated wh ls distct cerebral sexual together, although extant fdgs suggt that human sexual orientatn is associated wh bra morphology, the heterogeneo and limed number of studi preclus a thorough unrstandg of the shared and distct nral signatur of sexual orientatn men and women.

MethodsParticipantsMRI data of 37 men (21 homosexual men = HoM; 16 heterosexual men = HeM) and 37 women (19 homosexual women = HoW; 18 heterosexual women = HeW) entered the analys (see Supplementary Table 1 for sample mographics; N = 74).
