Researchers have found that the male brain is hardwired to seek out sex, even at the expense of a good meal, with specific neurons firing up to over-ride the desire to eat. Intriguingly, women do not have the same neurons, suggesting that sex for females comes secondary to sustenance. Although the neurons have only been found in the brains of nematode worms, scientists at University College London say that it is likely that similar mechanisms are at work in humans. And it is proof that male and female brains are wired differently, a controversial subject, which has been argued by scientists and feminists for decades. Co-author Professor Scott Emmons, from the Departments of Genetics and Neuroscience at Albert Einstein College of Medicine, said: "Though the work is carried out in a small worm, it nevertheless gives us a perspective that helps us appreciate and possibly understand the variety of human sexuality, sexual orientation, and gender identification. This may change how the two sexes perceive the world and their behavioural priorities. The team were surprised to find the new cells because the worms have been studied by extensively in the past and it is the first time they have been spotted.
