STUDY SAYS BRAS OF GAY MEN AND WOMEN ARE SIAR
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 ap psychology *
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).

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.
3D T1-weighted MRI sns were reoriented to the termissural plane, rrected for field tensy homogenei, and spatially normalized onto MNI standard space.
