Gay Brains - A New Study
New research, utilizing brain scans of 90 volunteers, is being described as the "most robust measure" made of differences in brain structure and activity between gay and straight people.
The scans reveal that in gay people, key structures of the brain governing emotion, mood, anxiety and aggressiveness resemble those in straight people of the opposite sex.
U.S. News reports:
MRI and PET scan studies are showing remarkable similarities between the brains of gay men and straight women, and between those of lesbians and straight men.
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.
On the other hand, the brains of gay men and straight women are both symmetrical.
Similar trends emerged when scientists tracked connectivity in the amygdala, the region of the brain involved in emotional learning and in activating the fight-or-flight response. They noted strong similarities between gay men and straight women, and lesbians and straight men.
This significant study adds to the growing evidence pointing to a biological connection with homosexual orientation. For Latter-day Saints, the findings of this new research give us all the more reason to reject the view that homosexuality consists merely of what a person does. It points us toward the understanding, long advanced by gay people themselves, that it's "who you are."
