科学家们扫描女性性高潮时的脑部变化照片发现，性高潮过程涉及逾30个不同脑区，而
且在达到高潮的每一阶段，脑部活动都会增加，不但影响脑内的回馈线路，负责理想思
考的脑区也会受影响，让痛楚感觉暂时纾减。
美国Rutgers大学脑神经科研人员利用计算机素描，首次拍摄女性在进入和达到性高潮
时的脑部活动情况。研究中，8名女性躺进磁力共振影像扫描机(FMRIS)内，盖上毛毯自
慰，仪器每隔两秒就拍下一张脑扫描照。大部分人能在5分钟内达到高潮，一些人则需
时20分钟。
参加者以举手示意达到高潮，结果发现，部分女性在一个阶段内多次举手，而且仅相隔
数秒，反映女性性高潮时间较长，而且会连续经历多次。女性性高潮大多维持 10至15
秒，亦有其它研究指平均不足20分钟。 研究员下一步计划对男性进行同类的脑部素描
，研究女性性高潮是否比男性持久和更深入。
“The brain becomes very active as someone approaches orgasm,” Komisaruk
explains. He, Wise and the other research associates have found that four
different pairs of nerves — hypogastric, vagus, pudendal and pelvic —
carry information from the woman’s genital area via the spinal cord to her
brain.
As this information registers in the brain, chemical messengers start doing
their work.
Dopamine and oxytocin are let loose — the dopamine stimulates the pleasure
sensations as oxytocin, which is released throughout the bloodstream,
initiates the uterine contractions that often accompany orgasm.
A woman also experiences accelerated heartbeat, blood pressure, flushness,
pupil dilation and sweating — orgasm is a full-body workout. Because there
are so many pathways for sensation, Komisaruk believes a woman has the
capacity to experience a more intense and complex orgasm than a man.
Some women can create the sensation of orgasm from thought alone, without
touch. In slang, the phenomenon is called “thinking off.” Komisaruk and
Wise have studied these women with extreme interest.
“Our mind is much more powerful than we imagine,” says Wise. “If we can
become aroused by thoughts, why not orgasm from them?”
Traci, a 30-year-old woman who has given an orgasm to Komisaruk’s fMRI,
discovered her ability to “think off ” while chatting online. “It just
kind of happened,” she says, “I don’t know how it happened. I think I’m
just really horny.”
Though she has harnessed a skill many women would pay big money for, she
rarely will just pop one out while she’s out and about. “I haven’t really
done it much,” she says, “but you know what? I probably should.”
When she went through the fMRI, she brought herself to orgasm using her
special skill — without touching herself.
