Fascinating:

Using MRI scans of gay and straight men and women, the researchers found that people who liked women — heterosexual men and homosexual women — had larger right brain hemispheres, while people who liked men — heterosexual women and homosexual men — had symmetrical brains. As seen in the image, MRI and PET scans showed a similar pattern in two specific regions of the brain, the right and left amygdalas, which are thought to control fight-or-flight reactions.
