研究:性让女人收心 却让男人花心

Sex is one of our biggest preoccupations — causing thrills, heartache and downright confusion. But until recently, exactly what happens in the brain during sex was something of a mystery to scientists. Now, however, American researchers have uncovered what goes on in a woman’s head during an orgasm. The scientists from Rutgers University, New Jersey, used scans to monitor women’s brains during orgasm and found that different brain parts are activated when various parts of her body are aroused.

性爱作为一门复杂的学问千百年来是人们希望探索的一个隐秘的领域、它既可以使人肾上腺素激发、也可以让你头疼不已、或者会为你制造许许多多的大麻烦、幸运的话它可以让你在婚姻中幸福美满。科学家近日对女性在性爱过程中脑部的状态进行的实验和分析，他们认为女性被性爱左右的程度要相对男性高太多太多。据悉，来自新泽西州Rutgers大学的科学家用脑部扫描分析了处与高潮中女性脑部的状态后发现，在女性大脑中，有30个不同区域被性爱“唤醒”。

They found that up to 30 different parts of the brain are activated, including those responsible for emotion, touch, joy, satisfaction and memory. The scientists found that two minutes before orgasm the brain’s reward centres become active. These are the areas usually activated when eating food and drink. Immediately 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.

科学家将处于高潮前两分钟大脑状态的示意图与处于高潮后的状态做对比，发现高潮后的大脑区域中，有负责情感的、触觉的、开心的、满意度的还有记忆的区域与之前有相当大的不同，这些区域只有在平时吃饭以及喝水状况下才处于活跃状态，专家称，女性大脑在高潮状态中负责管理这些情绪的区域都处于“活跃状态”。

The final part of the brain to be activated is the hypothalamus, the ‘control’ part which regulates temperature, hunger, thirst and tiredness. The scientists also discovered that sexual arousal numbs the female nervous system to such an extent that a woman doesn’t feel as much pain — only pleasure. The team now hopes to map what happens in a man’s brain during orgasm. But what else is happening inside our heads when we slip between the sheets? Here we ask the experts to reveal how sex alters our brain.

还有一个被“激发”的领域为“丘脑下部”，这个部位位于大脑腹面、丘脑的下方，是调节内脏活动和内分泌活动的较高级神经中枢所在，具有“控制”的职能，管理人的体温、饥饱程度以及疲惫程度。科学家还发现处于高潮状态的女性疼痛感不明显，神经系统感觉“痛苦”的部位处于麻痹状态，愉悦感比较多。

Men, on the other hand, instead of getting a surge of bonding hormone receive a surge of simple pleasure. ‘The problem is that when a man has an orgasm, the main hormone released is dopamine — the pleasure hormone. And this surge can be addictive,’ says Dr Ghosh. That’s why so many more men tend to suffer from sex addiction.

然而，科学家将男性处于兴奋状态的大脑与女性相比，那一句话：男人是用下半身思考的动物就很能说明问题，一般来说，男人在高潮时大脑中，大脑就会释放出多巴胺，这种激素会让男性对性爱上瘾，这也就是为什么需要治疗“性成瘾”的男性人数要多于女性人数的原因了。

A lot of sexual health research focuses on what’s happening physically. But experts say that for many people — especially women — the mind plays a key role in achieving orgasm. While male brains tend to focus on the physical stimulation involved in sexual contact, the key to female arousal seems to be deep relaxation and a lack of anxiety.

科学家分析，女性在性爱过程中，多数是“精神上的愉悦”，而对于男性而言起到关键性作用的只是物理上的刺激，对于女性而言，性爱是放松、缓解疲惫的方式，这种方式会让女人觉得这个男人就是自己的另一半，而对于男人来说，性爱就是性爱，男人不会产生更多的联想。
