高潮是什么样的体验？

以下为视频中的字幕：
The human body is a wonder,
人体就是一个奇迹。
But perhaps the most curious and quintessential aspect of the human experience is the orgasm.
而人类体验中最奇特的也许就是性高潮了。
The body's sexual response is typically broken down in four stages, excitement, plateu of arousal, orgasm, and resolution.
性反应通常分为四个阶段，兴奋、唤起、高潮和消退。
Following arousal, the brain stimulates blood flow to the genitals, your heartbeat and breathing increase, and the central nervous system is fully engaged, sending signals of enjoyment to the brain's reward system.
在性唤起后，血液流向生殖器。你的心跳和呼吸速率增加，中枢神经系统完全兴奋，将兴奋信号发送到大脑的奖赏系统。
These thousands of nerve endings constantly relay pleasure signals to the brain, resulting in an orgasm.
成千上万的神经末梢不停将愉悦信号传递给大脑，形成性高潮。
For men, the orgasm includes rapid contractions of the anal sphincter, the prostate, and the muscles of the penis.
对于男性来说，性高潮包括肛门括约肌、前列腺和阴茎肌肉的快速收缩。
In conjunction with ejaculation, which sees the release of sperm and other seminal fluid, the whole process for men involves around three to ten seconds of intense pleasure.
射精包括精子和其他体液的释放，男性在整个高潮过程中能享受3－10秒的强烈愉悦。
This is followed by a refractory period for minutes to hours in which another orgasm cannot be achieved.
接下来的几分钟到几个小时内是男性的不应期，这期间不能达到下一个性高潮。
Women, on the other hand, do not experience a refractory period, allowing them to experience multiple consecutive orgasms.
但女性是没有不应期的，这使得女性能够连续多次高潮。
On average, these last for around twenty seconds, though sometimes much longer.
平均而言，女性的高潮会持续大概二十秒左右，尽管有时时间长的多。
And consist of rhythmic contractions between the uterus, vagina, anus, and pelvic muscles.
女性高潮包括子宫，阴道，肛门和盆腔肌肉的节律性收缩。
But it's the brain that takes control or rather, lack thereof during orgasm.
但是归根结底是大脑控制高潮，或者大脑的失控带来高潮。
Using functional MRI scans, scientists are able to see brain activity in over 30 discreet regions.
通过功能性核磁共振扫面，研究者在超过三十个大脑区域观察到和高潮有关的活动，
It's flooded with the anticipatory and feel-good chemical dopamine which makes you crave the feeling again.
这些大脑区域涌动着的让你感觉良好、和预期有关的化学物质多巴胺，让你渴望再次经历这种感觉。
This is in tandem with the release of Oxycontin, a hormone that mediates bonding and love between mates.
这与催产素的释放同时发生，催产素是一种调节配偶结合和恋爱的激素。
PET scans show surprisingly that brain activity during an orgasm is the same between men and women.
神奇的是，PET扫描显示男性和女性在性高潮期间的大脑活动是相同的。
In both genders, the lateral orbitofrontal cortex is turned off which controls self-evaluation, reason, and control.
男女都在高潮时抑制了外侧的眶额叶皮质，它负责控制自我评估，推理和自控。
Makes sense, as you often lose control during orgasm.
这很合理，因为你在高潮时往往失去控制。
This shuts down fear and anxiety, which is seen as the most essential aspect leading up to orgasm.
这也“关闭”了恐惧和焦虑，这被认为是导致性高潮最重要的因素。
The relaxation of the Amygdala and hippocampus in women further reduce emotions, producing a trance-like state, while in men, it dampens aggressiveness.
女性杏仁核和海马体的放松又进一步削弱了情绪，催生了一种恍惚状态。而在男性中，它抑制了侵略性。
Many areas of a woman's brain are shut down completely during an orgasm.
在性高潮时，女性大脑许多区域被完全“关闭”。
These effects are less striking in men, likely because of the shorter duration and difficulty with measuring during brain scan.
这些影响在男性中不太显着，可能是因为高潮持续时间过短，使得脑扫描存在困难。
In women, an area called the periaqueductal gray or PAG is activated, stimulating the flight or fight response, while the cortex, which is associated with pain lights up, suggesting that there is a connection between pain and pleasure.
在女性中，称为中脑导水管周围灰质（PAG）的区域被激活，引起“战斗或逃跑”反应；而与疼痛相关的皮层亮起，表明疼痛与快感之间存在关联。
Following this climax and muscle contraction, the body experiences deep relaxation and heart rate slows to a resting pace.
高潮和肌肉收缩之后，身体会深度放松，心率也会放慢到一个休息的速度。
Who knew science could be so sexy?
谁又知道科学是如此性感呢？
