研究:性讓女人收心 卻讓男人花心

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.

性愛作爲一門複雜的學問千百年來是人們希望探索的一個隱祕的領域、它既可以使人腎上腺素激發、也可以讓你頭疼不已、或者會爲你製造許許多多的大麻煩、幸運的話它可以讓你在婚姻中幸福美滿。科學家近日對女性在性愛過程中腦部的狀態進行的實驗和分析，他們認爲女性被性愛左右的程度要相對男性高太多太多。據悉，來自新澤西州Rutgers大學的科學家用腦部掃描分析了處與高潮中女性腦部的狀態後發現，在女性大腦中，有30個不同區域被性愛“喚醒”。

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.

科學家將處於高潮前兩分鐘大腦狀態的示意圖與處於高潮後的狀態做對比，發現高潮後的大腦區域中，有負責情感的、觸覺的、開心的、滿意度的還有記憶的區域與之前有相當大的不同，這些區域只有在平時吃飯以及喝水狀況下才處於活躍狀態，專家稱，女性大腦在高潮狀態中負責管理這些情緒的區域都處於“活躍狀態”。

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.

還有一個被“激發”的領域爲“丘腦下部”，這個部位位於大腦腹面、丘腦的下方，是調節內臟活動和內分泌活動的較高級神經中樞所在，具有“控制”的職能，管理人的體溫、飢飽程度以及疲憊程度。科學家還發現處於高潮狀態的女性疼痛感不明顯，神經系統感覺“痛苦”的部位處於麻痹狀態，愉悅感比較多。

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，科學家將男性處於興奮狀態的大腦與女性相比，那一句話：男人是用下半身思考的動物就很能說明問題，一般來說，男人在高潮時大腦中，大腦就會釋放出多巴胺，這種激素會讓男性對性愛上癮，這也就是爲什麼需要治療“性成癮”的男性人數要多於女性人數的原因了。

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.

科學家分析，女性在性愛過程中，多數是“精神上的愉悅”，而對於男性而言起到關鍵性作用的只是物理上的刺激，對於女性而言，性愛是放鬆、緩解疲憊的方式，這種方式會讓女人覺得這個男人就是自己的另一半，而對於男人來說，性愛就是性愛，男人不會產生更多的聯想。
