Quote: Charles Panati. Sexy Origins and Intimate Things (1998): ' Salk Institute researcher Simon LeVay studied forty-one brains and found that part of the hypothalamus was smaller in gay men than in straight men- about only half the size. He also found that a tiny region of the hypothalamus, which is involved in sexual behaviors, was, in gay men, more like that found in women than in heterosexual men. He looked at four different grouping of cells, technically referred to as the interstitial nuclei of the anterior hypothalamus, or INAH. Others had already reported that INAH 2 and 3 were larger in men than in women. He found that the INAH-3 areas of most of the women and the gay men were about the same size. In straight men, this region was on average twice as large - about the size of a grain of sand. The LeVay study was the second to find a difference between the hypothalamuses of gay and straight men. In 1990, a Dutch team discovered that another group of neurons in the same tiny gland was larger in homosexuals than in straight men. Some scientists believe that this structure governs daily rhythms, not sexual behavior.'
