Comparing Brain Scans

A provocative new study has produced more evidence that the brains of homosexual men and women tend to differ from those of heterosexual men and women. This image contains a series of brain scans of homosexual and heterosexual men and women, focusing on a part of the brain involved in processing emotions known as the amygdala. The brains of homosexual men appear more similar to those of heterosexual women than heterosexual men while homosexual women appear more similar to heterosexual men than heterosexual women.
