'Sex chip' will have us wired, Oxford University researcher says

FORGET Viagra scientists are working on an electronic "sex chip" that will be able to stimulate pleasure centres in the brain The Australian reports. The prospect of the chip is emerging from progress in deep brain stimulation in which tiny shocks from implanted electrodes are given to the brain. It has already been used to treat symptoms of Parkinson s disease. In recent months scientists have been focusing on an area of the brain just behind the eyes known as the orbitofrontal cortex. This is associated with feelings of pleasure derived from eating and sex. A research survey conducted by Morten Kringelbach senior fellow at Oxford University s department of psychiatry and reported in the Nature Reviews Neuroscience journal found the orbitofrontal cortex could be a "new stimulation target" to help people suffering from anhedonia an inability to experience pleasure from such activities. Stimulating this area can produce pleasure as intense as "devouring a delicious pastry" he said. His colleague Tipu Aziz a professor of neurosurgery at the John Radcliffe hospital in Oxford predicted a significant breakthrough in the science behind a "sex chip" within 10 years. "There is evidence that this chip will work " Dr Aziz said. "A few years ago a scientist implanted such a device into the brain of a woman with a low sex drive and turned her into a very sexually active woman. She didn t like the sudden change so the wiring in her head was removed."
