COPENHAGEN
(Reuters) - Women may be able to fool their partners byfaking an orgasm
but a brain scanner will catch them out every time, aconference heard
Monday.

Researchers at the University of Groningen in the
Netherlands have usedscans to show that different areas of the brain
are stimulated duringan orgasm but are not activated when a woman fakes
it.

"Women can imitate orgasm quite well," Gert Holstege told a
fertilitymeeting Monday. "But there is nothing really happening in the
brain."

He and colleagues took brain scans of 13 women and 11
men, aged 19-49who had volunteered for the study, while they were being
sexuallystimulated by their partner and during an orgasm and compared
them toimages of their brains at rest.

"We wanted to know what the brain was doing during orgasm," Holstege said.

When
women genuinely achieved an orgasm, areas of the brain involved infear
and emotion were deactivated. Those areas stayed alert howeverwhen
women were faking it.

The researchers also found that the cortex,
which is linked withconsciousness, is active during a fake orgasm but
not during the realthing.

"The deactivation of these very
important parts of the brain might bethe 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 letyourself go," he added.

The brain scans for men during orgasm were less conclusive, according to Holstege.

But they did show that different parts of the male and female brain are activated and deactivated during sexual stimulation.

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

They are now planning further studies to compared the male and female brains during orgasm.
