Study Says Brains of Gay Men and Women Are Similar
Brain scans provide evidence that sexual orientation is biological
Researchers using brain scans have found new evidence that biology—and not environment—is at the core of sexual orientation. Scientists at the Stockholm Brain Institute in Sweden report in the Proceedings of the National Academy of Sciences USA that gay men and straight women share similar traits—most notably in the size of their brains and the activity of the amygdala—an area of the brain tied to emotion, anxiety and aggression. The same is true for heterosexual men and lesbians.
Study author, neurologist Ivanka Savic–Berglund, says such characteristics would develop in the womb or in early infancy, meaning that psychological or environmental factors played little or no role.
were the brain scans done on infants and then compared with their behavior as adults?

the window for psychobiological change never slams shut. The new neuroscientific findings have upended the deterministic view that brain development is essentially over by age 3. Although the most rapid period of brain growth occurs during early childhood, the brain continues to change throughout adulthood. --
--Teicher and his colleagues used brain scans to compare 15 child victims of severe abuse with 15 healthy volunteers.
The left cortex of the abused group was underdeveloped. Likewise, studies by Dr. Douglas Bremner of Yale and Dr. Murray Stein of the University of California at San Diego have found that the left hippocampus is smaller in abuse victims.--

Abuse also damages the amygdala, an almond-shaped cluster of nuclei located in the brain's emotional control center that enables us to respond quickly to danger--
