Further tests suggest gay is hard wired in the brain
Sexuality is pre determined by the part of the brain that deals with desire, according to research that is set to stir up the â€œnature or nurtureâ€ debate once again.
According to a report in the Chicago Tribune, the University of Chicago has found that the centre of sexual feelings in the brain, known as the hypothalamus, is distinctly different in gay and straight men.
A study of 8 solely heterosexual and 8 solely homosexual men found that straight men have more activity in their hypothalamus than their gay counterparts, indicating that there is a physical and neurochemical difference between sexualities.
Researchers studied this part of the brain after it was revealed to control sexual feelings and desire in animal studies, the paper reports.
“Whether this neurochemical difference is the cause of, or a consequence of, or something that accompanies this kind of heterosexuality and homosexuality is yet to be determined,” the Universityâ€™s Howard Moltz said.
“But it’s the strongest research I know to suggest that it might be hard-wired.”
Moltz says he is yet to study the difference between lesbians and straight women, but is keen to see if the difference is the same.
Recently, the issue of whether homosexuality is determined before birth has made headlines once again, with studies claiming to prove that there is a physical difference between gay and straight men.
This summer, a London study claimed that straight and gay men have different blinking reactions and that this proves that sexuality is an innate difference.
The University of East London studied the startle response to sudden loud noises, and found that sexuality led to different reactions.
Researchers said this proved that sexual orientation is â€œhard-wiredâ€ into the brain in foetal development.
