Turn your brain off to orgasm

Women may be able to fool their partners by faking an orgasm but a brain scanner will catch them out every time, according to a report presented to the European Society of Human Reproduction and Embryology. Researchers analyzed the different parts of the male and female brain that are activated and deactivated during sexual stimulation.

When women genuinely achieved an orgasm, areas of the brain involved in fear and emotion were deactivated. Those areas stayed alert however when women were faking it. The researchers also found that the cortex, which is linked with consciousness, is active during a fake orgasm but not during the real thing.
"The deactivation of these very important parts of the brain might be the most important thing necessary to have an orgasm," said Holstege. "It means that if you are fearful or at a very high level of anxiety, then it is very difficult to have sex because you really have to let yourself go," he added.

The researchers found less deactivation in the males in the areas of the brain linked to emotion and fear when they were sexually stimulated.
