Do gay men have similar brains to women

Previous studies have examined brain differences between gay and straight people on the basis of their responses to various tasks, such as rating the attractiveness of other people. Overall, these specific brain regions in homosexual males tended to be similar to heterosexual women (more female‐typical), while these same brain regions homosexual women tended to be similar. Gay men, meanwhile, had symmetrical brains like those of straight women.

The team next used PET scans to measure blood flow to the amygdala, part of the brain that governs fear and aggression. For example, the brains of straight men and of gay women share certain common features: both are slightly asymmetric, with the right hemisphere larger than the left, say the Swedish researchers. Brain scans show similarities in shape and connections between gay brains and straight ones from the opposite sex.

The researchers added that the study cannot say whether the differences in brain shape are inherited or due to exposure to hormones such as testosterone in the womb and if they are responsible for sexual orientation.

But he cautions that these findings may vary in different people whose sexual orientation is not that clear-cutwhich his own research shows includes a majority of the population.

The images showed how the amygdala connects to other parts of the brain, giving them clues as to how this might influence behavior. Stream on. The same is true for heterosexual men and lesbians. Some research suggests that the brain activity of homosexual individuals in areas unrelated to sex mirror brain activity in straight individuals of the opposite sex.

Brain scans also showed the same symmetry among lesbians and straight men, the researchers wrote in the Proceedings of the National Academy of Sciences. The differences are likely to have been forged in the womb or in early infancy, says Ivanka Savic, who conducted the study at the Karolinska Institute in Stockholm, Sweden.
