The neuroscientist Simon LeVay trained at Cambridge University and served on the faculty at Harvard Medical School and the Salk Institute for Biological Studies. In 1991, he reported on a difference in the brain structures of gay and straight men. He provides an update on the brain science and considers whether the science of sexuality is relevant to the societal status of sexual minorities.
