揭秘：女性性高潮时大脑如何运转

The first scan revealing what happens inside a woman's brain when she has an orgasm has been developed by scientists. They have discovered that sexual arousal numbs the female nervous system to such an extent that she doesn't feel as much pain - only pleasure.
近日，科学家通过扫描检测到，女性在性高潮时大脑内部有所变化。他们发现，性刺激可以麻痹女性神经系统，使她们感受到的快乐更多，痛苦更少。

Researchers from Rutgers University asked eight women to stimulate themselves while lying under a blanket inside a Magnetic Resonance Imaging (MRI) scanner, a tunnel-like machine often used to detect brain tumors. Most women took less than five minutes to reach an orgasm. During that time, the MRI scanner took images of their brain to show which parts became active.
新泽西罗格斯大学的研究人员要求八位女性躺在装有磁共振扫描仪的毯子下进行自我刺激，大部分女性在五分钟内达到高潮。而在这五分钟内，磁共振扫描仪对其大脑进行拍照，以检查其大脑内部活跃部位。

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. Immediately before they reached the peak, other areas of the brain became affected such as the sensory cortex, which receives “touch” messages.
科学家们发现，在高潮前两分钟，大脑的奖励中枢开始活跃(奖励中枢通常只会经由“食”和“饮”来激活)。而在高潮的前一刻，诸如感觉皮层(负责接收“触觉”信息)这样的其他部位也开始受到影响。

once the orgasm has started other parts of the brain are activated such as those responsible for emotion - the cingulated cortex and the insula. The final part of the brain to be activated is the hypothalamus, the “control” part of the brain which regulates temperature, hunger, thirst and tiredness. At the same time another area responsible for pleasure is activated - the nucleus accumbens - as well as the caudate nucleus, which is responsible for memory.
高潮开始，负责情感的扣带回皮层、脑岛等大脑其他部位被激活。而最后一个活跃起来的是控制人体的温度、饥渴感觉以及困倦感的下丘脑。同时，另外一处负责“愉悦”感的伏隔核，以及负责记忆的尾状核也开始活跃起来。

Now the scientists also want to build up a similar picture for men so they can compare how the sensation affects the male and female brains.
如今科学家们正努力绘制出男性的高潮脑部变化图，以便比较高潮对两性脑部的影响究竟有何不同。
