A group of 90 gay and heterosexual adults were scanned by Swedish scientists

Did you know that a group of 90 gay and heterosexual adults were scanned by Swedish scientists to measure the volume of both hemispheres of their brain.

BBC published an article in 2008 about a Swedish study which reproted that The brains of gay men and women look like those found in heterosexual people of the opposite sex.

 

The study showed that structurally the brains of gay men were more like heterosexual women, and gay women more like heterosexual men.

A further experiment found that in one particular area of the brain, the amygdala, there were other significant differences.

In heterosexual men and gay women, there were more nerve “connections” in the right side of the amygdala, compared with the left.

The reverse, with more neural connections in the left amygdala, was the case in homosexual men and heterosexual women.

The Karolinska team said that these differences could not be mainly explained by “learned” effects, but needed another mechanism to set them, either before or after birth.
