STUDY SAYS BRAS OF GAY MEN AND WOMEN ARE SIAR

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.

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.

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

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.

BRAS DIFFERENT GAY, STRAIGHT PEOPLE

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.

GAY BRAS STCTURED LIKE THOSE OF THE OPPOSE SEX

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

3D T1-weighted MRI sns were reoriented to the termissural plane, rrected for field tensy homogenei, and spatially normalized onto MNI standard space. A homogeney check intified no outliers, th the GM volum of all 74 participants (21 HoM, 16 HeM, 19 HoW, 18 HeW) were clud subsequent analys: sexual orientatnFirst, whole-bra analys were performed g full factorial signs to pare GMV wh rpect to sexual orientatn (whole sample and per blogil sex, i.
