    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

    性高潮時我們的大腦堥s竟會發生什麼?科學家對於這個問題一直知之甚少。然而,近期,一段女性高潮時的腦部核磁共振成像首次向世人展示了性高潮時大腦埵釵h少區域受到影響。實際上,這段成像顯示,性高潮時,幾乎所有的大腦區域在都很活躍,這種狀態從與身體關聯的“愉悅中心”開始,逐漸蔓延至整個大腦。

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

    科學家表示,性高潮會影響超過80個大腦區域,而不是僅僅只影響幾個孤立的區域。

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

    這段影像由54歲的性治療師南·維瑟拍攝。當時,她自願坐進核核磁共振掃描儀,通過自慰讓自己達到高潮。

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

    新澤西羅格斯大學的心理學家巴堙P庫米薩勒克表示,希望這項研究將會幫助女性找到難以達到性高潮的原因。

    “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.”

    庫米薩勒克說:“這段核磁共振成像顯示了一名參與者在經歷性高潮時的大腦圖像數據, 不同大腦區域間相應的關係也可以由血液中的氧含量水平得出。氧含量水平呈現于一個光譜中,從暗紅色(最不活躍)到黃色或白色(最活躍)。正如我們看到的那樣,性高潮幾乎‘點亮’了整個大腦,幾乎整個腦部都顯示為黃色,這說明性高潮時絕大部分大腦系統都處於活躍狀態。”

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

    看上去,性高潮時的大腦內部就像是一場煙火表演。

    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.

    這段影像展示了這種活躍狀態是如何在感覺皮層(位於與生殖器有關的特殊區域)產生的,但這種活躍通過與情緒和記憶有關的大腦邊緣系統迅速蔓延。

    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.

    伴隨著性高潮的來臨,下丘腦的活躍值達到頂峰,這一區域會釋放一種叫做催產素(又名“擁抱荷爾蒙”)的化學物質。性高潮後,整個大腦活躍值降低。

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

    科學家希望,通過對這些過程的進一步了解,為那些無法到達性高潮的患者帶去福音。
