Your sexual orientation may be linked to brain configuration

According to Healthzone.ca (part of the website of The Toronto Star), a study has found similarities in MRI scans both between the brains of gay men and straight women and between the brains of lesbians and straight men (“Gayness linked to brain”).

A new Swedish study shows significant similarities between the brains of homosexual men and straight women and between the brains of lesbians and heterosexual men. Some researchers are saying this provides important proof that people are born gay and don’t choose to act that way.

The article adds:

“There are now about three or four studies on gays that point to a different organization in the brain,” says McMaster University neuroscientist Sandra Witelson.
 
“And what I think this means … is that these are differences that can’t be explained by any environmental or learning factors . . .”

The study found key differences in the size and functioning in the left and right hemispheres of homosexuals’ brains, compared with those of their heterosexual counterparts.
