Orgasm makes women sense only bliss
London, Nov 08 2010: Scientists hope to map what typically happens inside a woman’s brain when she has an orgasm.
Scientists claim to have finally revealed what goes on inside a woman’s brain when she has an orgasm — sexual arousal numbs female nervous system to such an extent that she doesn’t feel as much pain, only pleasure.
Using a scan, an international team, led by Rutgers University, has also found that the orgasm affects up to 30 different parts of the brain including those responsible for emotion, touch, joy, satisfaction and memory.
The scientists hope to be able to map what typically happens inside a woman’s brain when she has an orgasm — this could enable them to pinpoint what is going wrong among those with problems of sexual dysfunction or low libido.
For their research, the scientists asked eight women to stimulate themselves while
lying under a blanket inside an Magnetic Resonance Imaging (MRI) scanner often used to detect brain tumours. Most women took less than five minutes to reach an orgasm while some took as long as 20; the MRI scanner took images of their brain every two seconds.
The scientists found that two minutes before the orgasm, the brain’s reward centers become active, the areas usually activated when eating food and drink.
Soon before they reached the peak, other areas of the brain became affected such as the sensory cortex, which receives “touch” messages from parts of the body and the thalamus, which relays signals to other parts of the body.
Once the orgasm has started other parts of the brain are activated such as those responsible for emotion.
The final part of the brain to be activated is the hypothalamus, which regulates temperature, hunger, thirst and tiredness. — PTI
