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

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.

GAY BRAS STCTURED LIKE THOSE OF THE OPPOSE SEX

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. 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.

Yet, our knowledge about possible cerebral differenc between homosexual men (HoM), heterosexual men (HeM) and heterosexual women (HeW) are extremely limed. The data suggt both sgular and sex atypil featur and motivate further vtigatns of cerebral midle stctur relatn to male homosexualy.

STUDY SAYS BRAS OF GAY MEN AND WOMEN ARE SIAR

One is whether MRI methodology uld be ed to vtigate whether there are any stctural bra differenc between homo and heterosexual persons. Several early post mortem studi suggt stctural/histologil differenc between homosexual men (HoM) and heterosexual men (HeM) along the cerebral midle.

Reported creased homogeney rtg state bra activy (suggted to reflect lol functnal nnectns) mid ontal lobe and creased homogeney the middle and ferr occipal lobe [1]. While ngently suggtg a ls pronounced or atypil sexual differentiatn of cerebral midle stctur, most of the studi vtigated a sgle stcture, or ed a sgle metric, and none really addrsed the qutn as to whether the tected differenc between homo- and hetero-sexual persons reflected a wispread atypil cerebral sex dimorphism, cludg several different facets of bra stcture, among HeM or rtrictive chang around the cerebral midle. In the prent study, which is part of a larger effort to elucidate the possible nroblogy of sexual orientatn and genr inty, stctural and rtg state functnal MRI have been utilized tanm to vtigate possible cerebral rrelat to male homosexualy.

We specifilly asked ourselv whether the bras of homo and heterosexual men were anatomilly different, and how the differenc were related to the differenc rrpondg measur between HeM and HeW.

HeM and HeW sred 0–1 and HoM sred 5–6 on the Ksey heterosexual/homosexual sle (0 = maximally heterosexual, 6 = maximally homosexual) [10, 37].

The 32-channel il was ed for all the sequenc; The 8-channel il was ed, addn, for acquisn of the 3D T1 imag (see further) as we found signal homogeniety at the ontal and occipal pol when employg the 32-channel il, not prent when g the 8-channel l.

Post hoc analys: Correlatn between Ksey sr and rtil asss whether the differenc Cth between homo and heterosexual men were specifilly lked to sexual orientatn, we rried out post hoc analys cludg all three study groups (HoM, HeM, and HeW), and ttg whether there was any signifint rrelatn between Cth and Ksey sr. Consirg that the three groups differed only wh rpect to their genr and sexual orientatn, is plsible to nsir that the potential nroblogil substrat of male homosexualy may be loted primarily regns around the cerebral midle.

GAY MEN, STRAIGHT WOMEN HAVE SIAR BRAS

None of our homo or heterosexual subjects had such diagnos, and there were no differenc between HoM and HeM wh rpect to Social Rponsivens Sr, which had been obtaed for another study (S1 Supplemental Informatn). While this is the first multimodal MRI study to suggt a lk between cerebral works and male homosexualy, the prent rults do not distguish environmental, geic, and hormonal effects, [the HoM group had normal ttosterone levels, as well as trogen levels (S1 Supplemental Informatn, S1 Table)].

ConclnThe prent observatns suggt that nronal works volved sexual aroal and self-referential procs (loted along the cerebral midle) may be lked to male homosexualy. Associatn of Cerebral Networks Rtg State wh Sexual Preference of Homosexual Men: A Study of Regnal Homogeney and Functnal Connectivy. 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).

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. 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.

BRAS DIFFERENT GAY, STRAIGHT PEOPLE

The rults showed that straight men had asymmetric bras, wh the right hemisphere slightly larger – and the gay women also had this asymmetry. 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. 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.

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.
