    Little is understood about what actually happens to our brains during orgasm - but a video taken an MRI scanner shows for the first time how many regions of the brain are affected. Actually, the video shows that almost every part of the brain 'iilluminates' during the orgasm - starting with pleasure centres associated with the body and spreading through the whole brain

    性高潮时我们的大脑里究竟会发生什么?科学家对于这个问题一直知之甚少。然而,近期,一段女性高潮时的脑部核磁共振成像首次向世人展示了性高潮时大脑里有多少区域受到影响。实际上,这段成像显示,性高潮时,几乎所有的大脑区域在都很活跃,这种状态从与身体关联的“愉悦中心”开始,逐渐蔓延至整个大脑。

    Scientists say that rather than a few, isolated areas of the brain being affected, the orgasm affects more than 80 brain regions.

    科学家表示,性高潮会影响超过80个大脑区域,而不是仅仅只影响几个孤立的区域。

    The scan was taken of Nan Wise, a 54-year-old sex therapist, who volunteered to sit in an MRI scanner while stimulating herself.

    这段影像由54岁的性治疗师南·维瑟拍摄。当时,她自愿坐进核核磁共振扫描仪,通过自慰让自己达到高潮。

    Professor Barry Komisaruk, a psychologist at Rutgers University in New Jersey, hopes that the research will help women who find it difficult to orgasm.

    新泽西罗格斯大学的心理学家巴里·库米萨勒克表示,希望这项研究将会帮助女性找到难以达到性高潮的原因。

    “This themagnetic resonance imaging shows brain data of a participant experiencing an orgasm - and the corresponding relationships seen within these different regions based on oxygen levels in the blood. Oxygen levels are displayed on a spectrum from dark red (lowest activity) to yellow/white (highest). As can be observed, an orgasm leads to almost the entire brain illuminating yellow, indicating that most brain systems become active at orgasm.”

    库米萨勒克说:“这段核磁共振成像显示了一名参与者在经历性高潮时的大脑图像数据, 不同大脑区域间相应的关系也可以由血液中的氧含量水平得出。氧含量水平呈现于一个光谱中,从暗红色(最不活跃)到黄色或白色(最活跃)。正如我们看到的那样,性高潮几乎‘点亮’了整个大脑,几乎整个脑部都显示为黄色,这说明性高潮时绝大部分大脑系统都处于活跃状态。”

    To watch, it's almost like a firework display.

    看上去,性高潮时的大脑内部就像是一场烟火表演。

    The film shows how activity sparks off in the sensory cortex - in the specific area related to the genitals. But it spreads quickly through the limbic system, involved in emotions and memory.

    这段影像展示了这种活跃状态是如何在感觉皮层(位于与生殖器有关的特殊区域)产生的,但这种活跃通过与情绪和记忆有关的大脑边缘系统迅速蔓延。

    As orgasm arrives, activity peaks in the hypothalamus, which releases a chemical called oxytocin ('the cuddle hormone'). After orgasm, the activity throughout the brain dies down.

    伴随着性高潮的来临,下丘脑的活跃值达到顶峰,这一区域会释放一种叫做催产素(又名“拥抱荷尔蒙”)的化学物质。性高潮后,整个大脑活跃值降低。

    It's hoped that further understanding of these processes will help patients who are unable to achieve orgasm.

    科学家希望,通过对这些过程的进一步了解,为那些无法到达性高潮的患者带去福音。
