New research indicates parts of the brain that govern fear and anxiety are switched off when a woman is having an orgasm but remain active if she is faking.
In the first study to map brain function during orgasm, scientists from the Netherlands also found that as a woman climaxes, an area of the brain governing emotional control is largely deactivated.
...For women, the scanner measured brain activity at rest, while they faked an orgasm, while their partners stimulated their clitoris and while they experienced orgasm.
Holstege said he had trouble getting reliable results from the study on men because the scanner needs activities lasting at least two minutes and the men's climaxes didn't last that long. However, the scans did show activation of reward centers in the brain for men, but not for women.
Holstege said his results on women were more clear.
...The most striking results were seen in the parts of the brain that shut down, or deactivated. Deactivation was visible in the amygdala, a part of the brain thought to be involved in the neurobiology of fear and anxiety.
