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. 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. 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.

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. 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. 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.

A group of 90 healthy gay and heterosexual adults, men and women, were snned by the Karolska Instute scientists to measure the volume of both sis, or hemispher, of their bra. When the rults were llected, was found that lbians and heterosexual men shared a particular "asymmetry" their hemisphere size, while heterosexual women and gay men had no difference between the size of the different halv of their bra. "In other words, the bra work which term what sexual orientatn actually 'orients' towards is siar between gay men and straight women, and between gay women and straight men.

GAY BRAS STCTURED LIKE THOSE 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. “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.

WHAT THE GAY BRA LOOKS LIKE

“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. An early post-mortem study found that a small regn of the anterr hypothalam was smaller homosexual men than heterosexual men, and no different om heterosexual women.

Overall, the specific bra regns homosexual mal tend to be siar to heterosexual women (more female‐typil), while the same bra regns homosexual women tend to be siar to heterosexual men (more male‐typil). Geic factors that are associated wh variatns some rtil stctur showed oppose effects on rtil volume male vers female homosexuals who reported same-sex sexual behavrs.

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). Participants were reced through universy bullet boards, Lbian, Gay, Bisexual, Transgenr, and Queer or Qutng + (LGBTQ +) anizatns Aachen, Cologne and surroundg areas, and by word-of-mouth remendatn. All participants were asked to dite their sexual orientatn at the time of measurement g a 1 to 4 sle rangg om (1) exclively homosexual, (2) predomantly homosexual, (3) bisexual, or (4) heterosexual.

Altogether, 19 homosexual men and 15 homosexual women intified as exclively homosexual, while two homosexual men and four homosexual women intified as predomantly homosexual.
